Summary: By reason of drawing a parallel between working quality of
engines with regenerated injectors and original ones, we tested, on
elektric brake, the parameters of engines with built in regenerated
injectors vs. original ones. We tested and developed a technology of
regeneration and defined a cost of the treatment. We found out that the
parameters of engines supplied with regenerated injectors do not differ
essentially from those with orginal ones, so, the quality was acceptable
and the cost made only 7 % from the price of original parts.
Keywords: injector, engine, regeneration, technology of regeneration, cost, engine brakes.

Summary: We tested tje exploitional reliability of regenerated
tractor parts, in particular engine heads. For that purpose we worked out a
special regeneration technology for engine heads that, we presumed, would
give best results. We regenerated 47 heads of fluid cooled 6-cylindrical
engines. The research was performed, continuously, during two working
seasons (900-1100 working hours during the season). The testing with
penetrating medium showed, method, no fissures.
By permanent observation of 47 regenerated engine heads
(inspection of working orders) we found out that four tractor engines
became troubled by reason of reappearance of fissures. The cost of a
regenerated part is 4,14 % in relation to a new one.
According to the results of the
research we drew a conclusionthat the result "good", during the
exploitation, will be attained in 83,5-99,5 % of the basic group, with 95 %
reliability. By testing the fail participation plausibility
hypothesis we found out that regenerated engine heads meet the requierments
in 95 % at the significance level of 5 %.
Keywords: enginehead, regeneration, cold welding, fissures, price, reliability,plausibility.

Summary: Conventional types of tillage on wheat production expends
most fuel, human and machine labour per area unit. The level of grain yield
has not been reduced significantly by the reduced tillage application but
the production value increasing is possible per tone yield. One should know
that while supplying farms with equipment for traditional agricultural
techniques. Further research is needed for the soil fertility improivement
by reduced tillage application, especially by the variant D and for crop
increasing yield in crop rotation.
Keywords: wheat, soil tillage, energy input, Croatia.

Summary: Days of the harvest period in the eastern part of Croatia
do not affect grain losses while combining (r=0,27). Grain losses on the
header range between 0,13 and 3,13 %, on thresher betweeen 0,14 and 2,42 %
of the yield. In 56 % of cases, grain loss was above 1 % of the yield. In
the central part of Croatia, harvest days affect grain loss (r=0,97).
Header loss was from 0,10-1,50 % and thresher loss from 0,03-3,12 %.Grain
losses over 1 % were seen in 45,7 % of the cases. The moving speed of the
combine on the researched areas from 1-1,2 m/s were not the casuse foe
grain loss (r=0,32).
Keywords: Croatia, grain loss, wheat.

Summary: The hypothesis that wheat grain yield could be increased by
20 % ormore by the system of stable tracks was justified by this trial, in
which yields were 20,62 % higher as a result og correct fertilisation, crop
protection and the abovementioned operations. The margin rows influence was
significantly expressed by wheat grain yield increase at the stable tracks
variant because of the mean grain yield of 9,69 t/ha was realised in
varistion from 8,39 to 12,01 t/ha.

Summary: We tested the reliability of single,characteristic motor
parts and the driving mechanism og John Deere tractors of type 4440 on PIK
"BELJE".Based upon results obtained we defined the reliability of tractors
with regard top tested regenerated elements.Tractor samples were obsered as
a system in which all regenerated elements were associated into units by an
ordinal connection.We made a reliability calculation on the observed
samples (undergroupp tractros) and its application probability to the main
group,or,other John Deere tractors.The results of the research show the
reliability of tractor samples at P=0,7366, or 73,66%.The reliability
observed during three exploatational seasons of tractors was at 95%,and the
exploitational probability 65-82% for the quality group "good".

Summary: Satisfactory sowing quality through surface and depth was
not realised for any of the trial variants. From the standpoint of energy
and some other aspects, reduced tillage is an improvement over single
tillage operations, but not for sowing quality. Satisfactory sowing
quality, especially with reduced tillage systems, is not feasible without
good sowing machines and soil preparation equiment. Reduced tillage could
be applied under circumstances of high education, tehnical skills and the
existence of good quality equiment.

Summary: In work was presented influence of drops number and drops
dimensions on coverness of wheat leaf area in three regimes of speeds: 2.0,
2.5 and 3.7 m/s. Results of derived regression analyse turns out an qvadrat
dependence between number of drops and covernes of leaf area in all speeds.
Betwen dimensions of drops in volume-area diameter and coverness of leaf
area regression turns on potentional dependance in all active speeds.
Keywords: number of drops, drops dimension, leaf area coverness

Summary: It was investigation content of availability water in
profil of soil during vegetation by gravimetrical method. Established was a
content of water in soil and soil capacity for water in corn densities of
80000, 60000, and 48000 plants/ha. For metioned soil was used down border
of plasticity Wp=38.5 mm. During vegetation period, in someagrotehnical
phases (operationes of preparation of sowing and two cultivation) was
measured a content of availability water in relation of down border of
plasticity. Values of content of availability water in recived from samples
of soil in natural condition, served for calibration of values is received
from samples of soil in destroyed condition. Established was a very high
correlation (r=0.958**, Y=-0.8274+1.1592X+-0.0061X2). Content of
availability, water in soil (mm) was the largest in the lower density, but
between densites of 60000 and 80000 plants/ha wasn't significant
diferences.
Keywords: content of availability water, soil capacity for water, down border of plasticity, preparation soil for sowing, plant density

Summary: In this work is presented abaut influence of different
tillage on the distribution seeds quality by surface and depth. The
researches werw carried out during 1993 in three variant of tillage-two
time with the disck harow, tillage conventional and planting+harowing. Soil
surfacing, efects of into great expense and the transverzal sssd
distribution and seed disposition by depth was analysed. Results is showed
unsatisfactory quality of sowing in all tillage variants. Reduced tillage
is satisfactory by energetic aspetcs, work productivty and seed before it
is to late in relation on the tillage conventional.
Keywords: variants of soil tillage, two times with the disc, harow tillage conventional, plant+harowing seed disposition, surface and depth

Summary: Mower-conditioner Hesston 6400 is combine machine amd
contain two operationes (mowing and conditioning). This machine posses
steely profile cylinders, which was green mass pressured (Moisture green
mass-18%) with short time of drying (Tešić and Veselinov 1990, Tešić and
Veljić 1990). The reserrches were carried out during 1993 0n areas of
agricultural economy "Sopot" in Vinkovci. Humidity in total green mass of
lucerne was monitored as well as partially in stem and leaf during two
days. It was variationes four different of linear-pressure and tree of
green mass flow (combine Mower conditioner with the comparation-tractor
Torpedo 46 kW+Mower "IMT-516"). With the increasing of linear-pressure
lucerne humidity was significantly few during two days, specially 01.VIII.
Green mass flow size is no to set a condition of significantly a reducing
of lucerne humidity, except 01.VIII Humidity reducing with higher flow mass
size was significantly in humidity was significant lower. Stem and leaf
humidity during two days was represented with correlation coefficient for
31.VII (r=0.992**, by square regression Y=-356.358+11.4005X+-0.0777X2) and
01.VIII (r=0.852**, by linear equation of regression Y=-79.0195+2.2273X).

Summary: Good combine preparation has considerable influence on
decreasing the number of breakdowns and better utilisation of working time
at the harvest. In the second investigated year, the number of malfunctions
was considerably lower than in the first. Damage number during the harvest
of both of the investigated years was approximately the same but the
repairing hold-up time was considerably lower in the second. Most instances
involved the combine reaper and threshing machine, especially on older
combines. During the harvest, the amount of time required for repairs
generally decreased.
