Summary: On the basis of data obtained at the water-measure station
Botovofor 20-year period the regime of the river Drava was analysed.Upon
the analysis of low and large waterflow, their trend ofsubsidence was
ascertained. Subsidence of the waters is theresult of anthropogenic
interventions in the river-basin. Usingthe method of cross-correlation
analysis, the way and the levelofcommunication between ground waters in
Prekodravlje and waters ofthe river Drava was ascertained. The opened
profiles with theinstalled piezometers showed the change of ground water
regime.The signs of gleization are the result of processes occurred
inprevious hydrologicall conditions, so that in recent conditionsthey are
of limited diagnostic significance.

Summary: Irrigation is not much practised in Croatia for the
followingmain reasons: costly equipment, considerable cots of
systemconstruction and inadequate understanding of irrigation benefits.
Namely, it is still taken that irrigaton is a means of droughtprevention
and since, on average, droughts occur every 3-4 years,psychological and
calculational reasons are always found forpostponing investment into
irrigation. This situation stillcontinues. Besides, our crop production is
still characterized bya narrow range of crops grown, considerable use of
chemicals andheavy machinery, discarding of farmyard manure and separation
ofcrop and animal production. Irrigation could not be fitted intosuch
technology. These facts have been long known in thedeveloped countries
where the modern technology of"agriculturewith irrigation " is being
applied. We recommend this approachfor this country as well.

Summary: Developement of agricultural land is one of the limiting
factorsof improvement of productivity in the major part of the territoryof
Croatia. On undeveloped land, the water regime presents thebasic
constraint. Likewise, on the major part of arable land thepotentials for
increased agricultural production are found inimprovement of the water
regime. The paper shows the presentsituation and analyses the problems
related to land developementmeasures, with suggested solutions for the
purpose of furtheragricultural developement of Croatia.

Summary: On experimental fields Oborovo-Rugvica and Ježevo,
theconsequences of absence of required additional measures andinadequate
maintenance are investigated. On alluvial and hypogleysoils after
installation of drains vertical deep subsoiling hasnot been applied, and on
amfigley soils the hydraulic filtermaterijal and the additional agrotehnic
measure - moling - havenot been applied. In the drain trench, above the
drain a "vault"has been formed at the depth between 30 and 65 cm, and the
soilpermeability in the drain trench is low. The paper gives
therecommendations for further approach to regulation of excesswater in
hydromorphic soils.

Summary: On the Experimental field Oborovo in the Sava river valley
theresearch and inspection of the status of the existing drainagesystem
(pipe drains) was carried out in the period from May 15,1991 to december
15, 1992. The research was carried out on thebasis of constant monitoring
of the surface and ground waterregime, soil moisture dynamics and drain
outflow. Duringobservation, a very short period was noticed during which
thepipe drainage was functioning with a very low intensity on asmall number
of observed drains. The lack of more frequent activeperformance of pipe
drains during the observation period ispartly the consecvence of the
specific hydrological situation,and partly of inadequate performance of the
existing drainagesystem.

Summary: The Experimental field Oborovo in Posavina is organized
toresearch optimal crop rotation systems and some aspects ofagricultural
technology. Concerning land resources, experiment isdone on drained vertic
amfigley, no agromeliorated. The plowlayer is silty clay loam. Subsoil is a
silty clay and and siltloam. Researched drained veric amfigley is of high
plasticity,neutral soil reaction and rather low content of available
P2O5and K2O.
The groundwater level during a summer period is mostly below onemeter
depth, thus upward flow rate and contribution ofgroundwater to root zone
are neglected or none. During a hot anddray period (may - september) in the
root zone very oftenprevail low content of available soil water (less then
50%).

Summary: The most frequent type of enviroment pollution in
agriculturalareas is that by nitrogen. Nitrogen is prone to washing out,
dueto weak connection to the colloidal soil particles, and inparticular the
nitrate form pollutes ground water andwatersources. The intention of the
two year trial was todetermine the influence of detailed tile drainage on
nitrogenconcentration in water evacuated from soil in productin areas.
Onthe basis of the results it may be stated that nitrogenconcentration in
drain water is not dependant on the combinationof detailed drainage
measures, and that the values obtained, onaverage, are around
internationally accepted values for clearwater.
Keywords: Nitrogen concentration (nitrate and ammonia form), washing out, detailed drainage, drain water, mineral fertilizing, maise, oats.

Summary: On the experimental melioration field Jelenščak which is
situated in the middle of river Sava,the influence of different systems of
drainage for regulation of excessive water on pseudogley-gley soil has been
investigated,for the purpose of safe,economical and ecologically acceptable
crop production.It has been established that different of
drainage(different distances of pipe drainage:15 m,20 m,25 m and30 m,with
gravel and withouth it, with subsoiling plus liming and without these
measures) on the experimental melioration field, act efficiently in the
regulation of the excessive surface and ground water at the acceptable
depth for growing crops.Moreover,the satisfactory average annual intensity
of discharging water of 1.5 mm/day has been established.The average annual
rinse(for all variances) of NO3-N and NH4-N nitrogen is 37.4 kg/ha NO3-N
and 3.52 kg/ha NH4-N.The height of yield of maize has been traced and
established.The average yield was 80 dt/ha of dry corn at the rate of 55.7
dt/ha to 93.4 dt/ha.By means of statistical analyses of variance(according
to split-split plot method),applyng F-test the justified difference in
height of yield has been decided among the variances.With the t-test the
justified difference for every examined fact is shown.
Keywords: Drainage systems of heavy soils, distance of pipe drainage, hydraulik filter ,subsoiling and liming in land drainage.

Summary: The objective of this laborotory-type study was to
demonstrate the influence of contet and mineralogical properties of clay
fraction on potassium and ammonium adsorpption/desorption processes in
solute-soil system.Samples of three soils were selected with regard to
different textural andmineralogical characteristics.The investigation of
solution-exchange phase equilibra in soils and cation exchange was base of
Gapon selectivity equation.
The fast supplement of interlaver in smectites was resulted in low vale of
AR Ko in vertisol. The same parametar in fluvisol suggest to significant
retainability of added potassium in soil solution As compared with those
results, vertic and pseudogley soils indicate higher values for ARoNH4, as
effect of higher intial ammonium status in solution. Alluvial soil
demonstrate similar AR values for each of two cations in
equlibrium.Pseudogley soil, along with quarz the dominant clay mineral and
considerable mica, shows increased potassium exchange selectivity as
compared with vertisol.

Summary: Irrigation in Croatia slightly applied. Nevertheless, the
necessities for the irrigation are obvious, especially on islands. Due to
insufficiency of precipitations in summer, there is the lack of 200 to 400
mm of water, which is dependant on location and growing crop. There is the
shortage of water suitable quality for irrigation. Therefore, it is
recommanded the building of water acumulation, covered with plasic sheet.
In islands conditions, there is adventage of application of localized
irrigation(drop irrigation, microsprinclers). In contemporaly irrigated
agriculture it is important to be skilled in water dosage, carried out on a
ecological principles.

Summary: During the two - year investigation works conducted in 1991
and 1992 at the Jelenščak Reclamation Test Field, Kutina, the
concentrations of NO3-N and NH4-N were monitored in drainage waters of
different pipe drainage systems, with pipe distances of 15m, 20 m, 25 m and
30 m, with the hydraulic filter material - gravel - or without it. The
investigations were performed in pseudogley and gley soils. In 1992, the
corn was cultivated, fertilized the total of 202 kg/ha of nitrogen, and in
1992 the oat was cultivated and fertilized with the total of 50 kg/ha of
nitrogen. The drainage water samples were analyzed for each year and all
pipe drainage system alternative four times. The results have proven that
the average concentration of NO3_N in 1991 ranged from the average minimum
value of 13.0 mg/l to the average maximum concentration of 16.3 mg/l. In
1992, the average concentration of NO3-N ranged from the average minimum
value of 11,0 mg/l to the average maximum value of 13.1 mg/l. The average
concentration of NH4-N in 1991 ranged from the average minimum value of
1.12 mg/l to the average maximum of 1.54 mg/l. In 1992, the determined
average minimum value was 0.53 mg/l to the average maximum concentration of
0.70 mg/l. The results were statistically analyzed and it was determined
that there were no significant differences between the alternative tests
with respect to the concentrations of the mineral forms of nitorgen (NO3-N
and NH4-N) washed out from the soil.

Summary: The research conducted at the Vransko jezero lake (Biograd)
for several years was intended to contribute to defining of the Vransko
jezero water regime, and to present the collected data on salt
concentration and origin so that they can be used when the solutions for
utilization of this water are looked for. The research results have proven
that the water level in the lake depends on the rainfall regime, and that
it can fall even below the zero level. In some rresearch periods the sea
level was higher than the lake water level which, due to the differential
hydrostatic pressure and specific hydrogeological condicitions, resulted in
ingress of the sea water into the lake. However, the water levels are not
monitored, as was statistically confirmed. The salt concentration in the
lake fluctuated even to five times, and its maximum value was reached in
the second half of 1990, when the lake water level was the lowest. The salt
concentration is in direct relation with the lake water level, which has
been statistically proven. The salt concentrations in the Main Canal are
considerably lower than in the Vransko Jezero lake, and they are both
related to the rainfall regime.
Keywords: The Vransko Jezero lake water, water regime, salt concentration.

Summary: Imotsko polje (ca 4500 ha) has the highest potential for
agricultural production in the broader area of Makarska. Seven basic
pedosystemic units were determined in the fild area by hydropedological
investigation carried out in 1990. On the basis of detailed analyses of
soil properties, as well as climatic, hydrological and geomorfological
conditions, limiting factors were defined for a practicable plant
production. Some major constrains are excessive soil moisture in the autumn
- winter period, water deficit during summer months, a shallow ploughlayer
poor in nutrients as well as a steep terrain slope in some places.
Regarding the constraints, ameliorative solutions are proposed, with
relevant standards for particular measures. The ultimate ovjective is
improvement of edaphic conditions to enable a stable and more successful
plant production in Imotsko polje based on acceptable ecological
principles.

Summary: In the agroecological conditions of Podravina, in summer
1992 and 1993, the investigations were carried out regarding the effects of
irrigation on the components of yields of millet, maize and dwarf French
bean as secondary crops. The results obtained show that irrigation affected
favourably both the vegetative and the generative stage of crop
development. Due to irrigation, the yield of millet was 5.4 times higher in
1992 and 1.6 times higher in 1993 than the yields in nonirrigated areas.
With irrigation, the yield of French bean was 4.5 times higher in 1992 and
2.4 times higher in 1993. All this speaks in favour of introducing of
secondary crops in order to achieve better land utilization, and additional
irrigation makes this production secure, which leads to more rational use
of the entire agroecological potential in the region of Podravina (Drava
river valley).

Summary: In the area of Prekodravlje (Croatia), studies of the
ground water dynamics in humofluvisol were carried out during the four-year
period. The results obtained indicate the existence of communication
between water level readings in individual piezometers. The defined ground
water dynamics does not correspond to the morphological signs of
hydromorphism of humofluvisol, from which it may be concluded that the
ground water regime has changed. With respect to the determined depth of
ground water, heterogenous profile stratigrphy, depth to the
geological-lithological substratum in the humofluvisol area, and to the
height of capillary rising, it should be pointed out that this does not
have any influence on reacharging of the agrological profile. The changes
in the ground water regime in Prekodravlje excludes its contribution to the
water balance which may, from the agronomic point of view, results in
droughts.

Summary: Well developed arable areas are the basic prerequirement of
successful crop production. Relative to the needs, there is little properly
developed land in this country. Therefore, the fast growing agricultural
production calls for urgent and detailed land amelioration mesures, the
ultimate aim which are high and quality yields. Since there is considerable
diversity in the geographical position, climatic characteristics, relief
and pedological conditions in Croatia, there is need for both drainage and
irrigation. Hydromorphic soils (hipogley, amfigley and pseudogley, as well
as certain alluvial-semigley soils) require regulation of surplus water,
whereas automorphic soils have to be irrigated. Open trenches have been
built on 33.5% of areas under amelioration, they need to by supplemented on
29%, while on 37.5% there are none at all and have to be built. Only 19.6%
of arable land has been provided with underground drainage ( pipe
drainage), while drain pipes have still to be laid on as many as 660.820
ha. In Croatia irrigations is applied to only 0,29% of arable land. There
are, however, number of reasons for irrigation:climatic features, permanent
growth of populationand reduction of arable land. Croatia has 680.000 ha
that have favourable hydropedological, topographic and hydrographic
conditions for irrigation. Private holdings are small here (averige size
2.9 ha, average plot 0.3 ha), so they should be enlarged by carrying out
land consolidation also on the remaining 79% of arable land. The
development of agriculture in Croatia requires more drainage for surplus
water regulation, irrigation to make up for water deficiency and measures
for improvement of agricultural areas and particular plots.

Summary: Crop water requirements are an important in designing of
irrigation system. There are several methods and approaches to determining
of crop water requirements and irrigation requirements. In this paper, the
computer programe"Cropwat" has been used. The objective of the paper is to
define water shortages, on the exemple of maize, which be coverd by
irrigation in the average climatic conditions on the territory of the
Republic of Croatia which is a prerequisite to attaining of full production
potencial of this crop. On the basis of the ten years mean climatic values
such as the monthly air temperature, relative air humidity, sunshine
duration and wind speed, the average annual reference evapotranspiration
has been determined according to the Penman method. The ETo values range
from 872 mm in Gospić i to 1730 mm in Dubrovnik. Keeping in mind the
development stage of maize, the crop evapotranspiration has been figured
out, as well as the average rainfall regime and the water deficit on 27
locations in Croatia. Irrigation requirements in the vegetation period are
the lowest in Karlovac (145 mm) and the highest in Hvar (591 mm). Based on
the results, and respecting the natural geographic features, by the
interpolation method maps have been worked out showing the average
reference evapotranspiration and water shortage in maize farming.
Keywords: Model, reference, evapotranspiration, crop evapotranspiration, irrigation, maiz.

Summary: The trial was set up on the experimental plot "Jelenščak",
Kutina located in the Lonjsko polje region, and involved investigation of
the influence of different pipe draing spacings, combined with
supplementary agromeliorative measures, on the water regime regulation in
hydromeliorated pseudogley-gley soil production. Four different spacings
between drain pipes (15, 20, 25 and 30 m), each with built-in hydraulic
filter material (gravel and without it (backfiling) with vertical deep
loosening + liming and without these measures, manifested good efficiency
with regard to regulation of surface and subsurface stagnating water at the
cropping depth. A saticfactory average drainage discharge, amounting to
215.5 mm or 25.7% of total precipitation, was recorded for all drain pipe
spacings. The length og the average drainage discharge period was 105 days;
it was shortest (85 days) in the case of the 15 m spacing with built-in
filter material and subsoiling and the longest(133 days) in the case of the
30, spacing without filter material and without subsoiling. The mean
drainage discharge intensity was 2.1 mm/day for all spacings. There soil
moisture phases (at a depth of 0-30 cm) were recorded at all spacings; the
ecologically favourable wet phase was the longest (very long) for all
spacings while the ecologically adverse dry was the shortest (long). Yields
of spring oats (Flemings regent variety) were monitored in the trial. The
highest yield of 44.6 dt/ha was determined at the drain pipe spacing of 15
m and the lowest, 35.2 dt/ha, at the drain pipe spacing of 30 m with no
filter material and no subsoiling. A statistically significant difference
in yields was obtained by statistical data processing (the split-split-plot
method). The drain pipe spacing of 15 m, with built-in filter material and
vertical deep loosening was significantly the best.

Summary: The principal task of hydrotechnical land amelioration is
carrying out of measures and works in order to establish and maintain water
and air regime in soil, in accordance with the requirements of modern
farming and optimum development of crops. Out of the total of 1,789.000
hectares of amelioration area, hydromelioration systems of surface drainage
have been completed on 33,5% and partly on further 29,0%, while subsoil
drainage systems have been installed on 19,6 % of the total requirements.
The areas sown in 1990 were on 73,3% of amelioration area in Croatia. A
particular problem occurs on 296.510 hectares of hydromeliorated areas
which are temporally occupied by enemy Serbian paramilitary troups, due to
high damages on hydromelioration works and facilities. Without the required
degree of completion of hydromelioration facilities and systems, and
without proper maintenance, there is no possibility to apply modern
agricultural technology in the process of production of agricultural crops,
which is the basic pre-condition for development of Croatian water
management.
Keywords: Hydrotehnical, land amelioration, water and air regime, soil, surface drainage, damages, hydromelioration facilities.

Summary: Most drainage systems in the narrow basin of the Sava River
Valley (ca 33,000 ha) area set up on vertic amphigley soils. Due to the
specific hydropedology and amelioration problems of this soil type, part
of the drainage systems involves combined detailed drainage (pipe drainage
with built-in contact material with or without application of
agromeliorative measures -soil moling). On a considerable part of the
mentioned areas, however, the traditional pipe drainage system was
implemented (pipe drainage without contact filter and without moling).
Investigations carried out on a number of typical locations in the Sava
Valley (Oborovo, Ivanić Grad, Nova Gradiška and Slavonski Brod) were aimed
at determining the extent of the functionality of the pipe drainage
installed on vertic amphigley in this region. Thus, a long wet phase (more
than 100 days) during the year was recorded in the rhizosphere layer on all
locations. During the prevalence of specific hydrological conditions (wet
soil phase), a low intensity od drainage discharge (0.1 - 0.3 l/s/ha) was
recorded on all locations. Deterioration of major physical soil properties
in the drain trench zone, especially in the subsoil horizon at a depth of
30-60 cm, was also determined for all locations. For instance, the
following was recorded in the drain trench zone relative to the natural
soil on the sides: reduction of total soil porosity (up to 5 vol.%) air
capacity (3 -5 %), vertical hydraulic conductivity (amounting to 10 cm/day
on all locations), penetration resistance (compaction). Marked variation
was observed in the yields of crops grown, as well as highly inadequate
(poor) maintenance of the existing drainage systems. On the basis of the
investigations carried out, we have arrived at the conclusion that the
functioning of pipe drainage on the locations at Oborovo (traditional pipe
drainage system) and at Nova Gradiška (pipe drainage with contact filter
and without moling) can be described as inadequante (poor), and as highly
inadequante (very poor) on the Ivanić Grad and Slavonski Brod locations
(traditional pipe drainage system). Consequently, the research results
point to the general conclusion that the majority of the drainage systems
on vertic amphigley in the Sava Valley are of poor to very poor efficiency.
Keywords: Drainage, functioning of drainage, vertic amphigley, filter material, drain trench, poor efficiency.

Summary: Efficiency of shallow drainage within the combined detailed
drainage system set up on vertic amphigley was investigated on the
experimental drainage field at Lug in the period of 1991/92. Shallow
drainage was done at an average depth of 65 cm, at a spacing of 20 m, with
contact material (natural gravel) backfilling above the drain trench up to
the plough layer (about 25 cm from soil surface). No supplementary
agrotehnical measure of moling was applied. The investigations were of
stationary type and were focused on the monitoring and determination of
water regime and actual soil moisture dynamics, drainage discharge
intensity (drainage hydromodule) and the yields of crops grown. It was
determined during the two year trial that the major influence on the soil
moistening regime, that is on the level of subsurface stagnant water and
groundwater, was that of precipitation and potential evapotranspiration. In
1991, for instance, the subsurface stagnant water level stayed below 50 cm
from soil surface for 10 months, while its shallower level was recorded
only during January and May. No longer presence og groundwater in the
traditional sence of the word, was recorded in the upper solum within 100
cm of soil depth. Based on permanent measurement of the actual soil
moisture, it was established that the soil moisture in the rhizospere laywe
(0-60 cm) was in 14,5% of the measured cases higher than the soil water
holding capacity and in 85,5% of the cases within the range of optimal soil
moisture. The highest degree of linear relation between soil moisture of
r=0.864 was obtained within the first and second soil layers (0-30 cm and
30-60 cm deep, respectively). In 1991, a drainage discharge coefficient of
0,233 was determined, which indicates that 23,3% of total annual
precipitation was drained by the existing drainage system. Maximum drainage
discharge rates of 5.5 l/s/ha, or 47.6 mm, were recorded. During a period
of five days (November 21-26, 1991), 80 mm, or 75%, of the total
precipitation that fell (105 mm) was drained by the system. The regression
equation obtained: y = 10.781 +0.6461 of precipitation allows the
conclusion that each additional mm of precipitation in the wet soil phase
will lead to an increase of drainage discharge by 0.65 mm. In the period of
1991/92, the achieved yield of oil rape, var. Jet Neuf, amounted to 3.4
t/ha. The obtained investigation results point to the conclusion that the
shallow drainage variant within the combined detailed drainage system on
the Lug location is marked by good efficiency and is, therefore,
recommended as an efficient solution for the draining of vertic amphigley
in this country.
Keywords: Shallow drainage, vertic amphigley, water regime, soil moisture, hydromodule (intensity), wet soil phase good efficiency.

Summary: The aim of the three-year field trial (1992, 1993 and
1994), carried out at the farme "Podravsko gospodarstvo"-Koprivnica, was to
determine the effect of irrigation on the yield of maize grown as secondary
crop. The trial involved four crops (millet, maize, string bean and
soybean) grown in the conditions with and without irrigation. The results
achieved point to the favourable influence of irrigation both on the
vegetative and generative crop development. In the conditions with
irrigation, millet yields were up to 5.4 times higher and those of silage
maize mass 1.14 to 3.1 times higher, depending on the hybrid and the trial
year. String bean rendered 4.5 times higher yields under irrigation. Of the
two soybean cultivars tested, RS 4033 achieved a 3.4 higher yield on the
irrigated plot, while AURA did not reach pysiological maturity. Considering
the obtained yields in terms of climatic conditions of a particular trial
year, it is noteworthy than even in the more than averagely humid years the
yields were significantly higher in the conditions involving irrigation.
Significant yield variations were recorded only on unirrigated plots in the
course of all three trial years. The results obtained point to the
conclusion that planting of secondary crops does not lead to a better
utilization of agricultural areas and ensures better production but
supplementary irrigation also enables efficient use of all agroecological
potentials in the Drava River Valley.

Summary: In the amelioration trial field "Jelenščak"- Kutina, in the
area of Lonjsko Polje (polder No 8), the research was carried was out in
order to test various system of detailed drainage, regulating excess water
in pseudogley-gley soil, for the purpose of achieving safer and mora
profitable agricultural production. It has been proved different drain
spacing (15, 20, 25 and 30 m, respectively) with and without filter
material (gravel), and with and without deep vertical subsoiling and
liming, show good effects regarding regulation of excess subsurface water
to the depth of 0.5 m, affecting crop production. On all alternatives of
detailed drainage, all three stages of soil humidity have been determined,
to the depth of the arable layer (0-30 cm). The ecologically favourable
humid stage of soil lasted very long in all alternatives. In 1990, drain
discharges were 107.2mm, or 14.2 percent of total rainfall to 116,8 mm(
15.4 percent), in 1992 from 249,8 (27.7 percent) to 278.9 (31 percent). In
1992, the drain discharge ranged from 202,1 mm (24,2 percent) to 239,8 mm
(28,6 percent). The duration of drain discharge was, in 1990, 69 to 97
days, in 1991, from 152to 201 days, and in 1992, 85 to 133 days. The mean
drain discharge intensity was 1.1 - 1.6 mm/day in 1990, 1.3 - 1.8 mm/day in
1991, and 1,7 - 2,7 mm/day in 1992. The yields monitored included wheat
(variety Marija), maize (hybrid c 492) and oat (variety Flemings regent).
In 1990, the yield of wheat was from 49.05 dt/ha to 59.54 dt/ha; in 1991,
the yield of maize was from 55.66 to 93.36 dt/ha, and in 1992. the yield of
oat was 35.24 to 44.56 dt/ha. The variance analysis showed that
statistically best alternatives were the drain spacings of 15 and 20 m (in
some results, also 25 m) with filter material-gravel and vertical deep
subsoiling and liming and these alternatives should be given the priority
in regulation of exess water in this area.
Keywords: Detailed drainage systems, pseudogley- gley, filter (contact) material-gravel, vertical deep subsoiling, liming, stagnant surface water, ecologically favourable humid stage in soil, drain discharge quantity, drain discharge duration mean drain discharge intensity crop yield.

Title: EFFECTS OF AGRICULTURAL AREA DEVELOPMENT ON THE FARME
"PODRAVSKO GOSPODARSTVO" KOPRIVNICA
Faculty: Agronomski u Zagrebu
Date of defense: 01/24/95
Language: hrvatski
Number of pages: 87
Summary: The paper presents the results of tests carried out on six
locations of the farm"Podravsko Gospodarstvo" with the of determining their
efficiency for improvement of crop production by comparing their status
before and after the application of agricultural land development measures.
Analyses of the conditions prior to the detailed land development revealed
an unregulated water -air regime as well as complete unfunctionality of the
existing drainage system. Indicators of land development efficiency were
analyzed in terms of the trench and path networks, shape and size of
production plots as well as the yields of crops grown. The achieved
investigation results allow the conclusion that, after the detailed
agricultural land development, the length of trenches and paths was
decreased while the arable areas increased. The number of production plots
was reduced and the average plot size increased. All of this resulted in a
considerable rise of wheat and maize yields.
Keywords: Agricultural area, crop production, water-air regime of the soil, indicators of development efficiency, trench and path network shape and size of production plots,yield.

Title: SELECTION OF THE DETAILED DRAINAGE SYSTEM FOR HYDROMORPHIC
SOILS IN THE VIROVITICA REGION
Faculty: Agronomski u Zagrebu
Author: STRIČEVIĆ IVO
Language: hrvatski
Number of pages: 141
Summary: Hydropedological problems of the Virovitica region (over
10,000 ha) were addressed with the emphasis on the occurrence of surplus
waters and the possibilities of their solution trough adequate detailed
drainage systems. Based on the hydropedological investigations conducted
for the needs of detailed drainage, the pedosystemic units determined were
divided into four amelioration zones of similar moistening problems and
similar physical and chemical properties, each with an adequate system of
detailed drainage. The third amelioration zone covers 38% of the areas
under study with predominantly marshy gley hypogley soils and, to a much
smaller extent, marshy gley amphigley soils (ratio 19:1). The fourth
amelioration zone comprises peat soils, which account for 4% of the areas
under study.
Keywords: Detailed drainage systems; alluvial, semigley, marshy gley hypogley and amphigley soils, peat soils, surplus water; systematic pipedrainage; deep loosening; mechanical filter; combined pipe drainage; mole drainage; hydraulic filter; open trench network.

Title: DETERMINATION OF BIOCLIMATIC COEFICIENTS FOR TOMATO
Faculty: Agronomski u Zagrebu
Author: KLAČIĆ ŽELJKO
Date of defense: 07/18/95
Language: hrvatski
Number of pages: 81
Summary: The trial was carried out on the experimental areas of the
Faculty of Agriculture Zagreb during the growing seasons of 1993 and 1994.
The research goal was to determine the decade values of bioclimatic
coefficients for tomato (var. Monte Carlo) grown in a sheltered space (High
tunnel) and in the open. Crop irrigation was conducted by the dripping
method. Water consumption for evapotranspiration was determined by the
method of water balancing on trail plots, in the soil layer of 0-30 cm, in
which tomato roots are developed. Values of bioclimatic coefficients,
determined on the basis of air temperature, relative air humidity and the
deficit of air saturation with water vapour for each decade in each growing
season were compared with the average decade bioclimatic coefficients. No
significant differences between the daily water consumption calculated on
the basic of the relevant (seasonal) bioclimatic coefficients and water
consumption calculated by means of the average bioclimatic coefficients
were determined for either of the trial variants by using of the three
methods of bioclimatic coefficient calculation. Accordingly, the average
values of bioclimatic coefficients can be used to calculate the daily water
requirements of tomato.
Keywords: Tomato, evapotranspiration, bioclimatic coefficients.

Type of work: Poster na 15th International Congress on Irrigation and Drainage,Hague, 1993.
Language: engleski
Summary: During the aggression on Croatia by Serbian military
formationsaided by the Yugoslav Federal Army in 1991 and 1992, great
damagewas caused to flood control works and hydroamelioration systemsand
structures in Croatia. A part of the problems in the contextof war is that
296.510 hectars of ameliorated land have beenoccupied by the enemy,
rendering impossibile sowing ofagricultural crops in 1991 and 1992, as well
as in spring 1993.The financial requirements for reconstruction of the
above wardamages is estimated to DEM 75,854,000.
