Summary:
Twenty-seven alfalfa cultivars, among which fourteen Croatian,
eight Serbian, one Macedonian, one Hungarian and three French,were
tested at test fields of the Osijek Agricultural Institute from
1987 to 1990. During four years of the investigation, the highest
digestible crude protein yield was obtained with the cvs.Slavonka
(13380 kg/ha) and Stela (13240 kg/ha), whereas the highest dry
matter yield was obtained with the cv. Debarska (733 dt/ha).

Summary:
This paper examined the effects that the type of alfalfa
variety and the climatic conditions had on the seed yield of
alfalfa. The investigation was carried out at test fields of the
Osijek Agricultural Institute from 1987 to1990.
The seed was produced from the second regrowth in 1988, 1989 and
1990 growing seasons. The first regrowth was used for the
production of voluminous fodder.
Averaged over three years, the highest yield was obtainedwith
the Osijek alfalfa variety Stela (962 kg/ha). Foreign alfalfa
varieties which were imported without the OECD Certificateattained
lower yields compared to the best domestically grown varieties.The
seed yield was strongly affected by the climatic conditions inthe
period from the flowering to the harvest. When considering the
growing seasons with low amounts of rainfall (51.1, 102.4 mm)
during the period from flowering to the harvest it can beconcluded
that the yields were considerably higher than those obtained in
growing seasons characterized by higher amounts of rainfall
(167.9 mm).

Summary:
Yield of kernels of field pea varieties used for theproduction
of voluminous fodder as well as of the varieties used for the
production of protein kernels were investigated at the Osijek
Agricultural Institute 1987-1989.
Among the varieties used for the production of voluminous fodder,
the highest yield was obtained with the varieties Miranda, Sirius
and Amino (results obtained during the two-year investigation),
whereas among the varieties used for the kernel production, the
highest yield was obtained with the Maxi, Jurak, Finale and Opal
(results obtained from the three-year investigation). During the
one-year investigation, the varieties Tyrkis, Dukat, Bohatyr and
Smaragd gave yields ranging from 39.4 to 40.8 dt/ha.

Summary:
The areas under alfalfa and red clover in Croatia occupy7.57
% of the total arable land. In this way, these crops are the most
frequently grown ones among the fodder crops.
The hay yield is unjustifiably low, so that 30 to 40 % ofthe
potential of the varieties is utilized.
There are good conditions for the production of alfalfa and
red clover seed in Croatia, yet, the production does not meet the
needs.
According to the dry matter yield and the protein
digestibility, domestic alfalfa varieties are as good as the best
European varieties.

Summary: Large socially-owned agricultural plants in Eastern Croatia
havebeen in possession of 43,6 % of total arable land. As for theprivate
farms, 31,8 % farms occupy an area smaller than 1 ha(data obtained in
1981), whereas 2,6 % farms own the area largerthan 10 ha. As for the crops
sown, cereals have been prevailing.The portion of fodder crops is low. The
yield of voluminousfodder and hay is low, too, because the most recent
technologicalachievements have not been applied on the one hand and there
areinsuffficient supplements and equipment on the other. The numberof
livestock units/ha is on the decrease. According to the dataof 1990, it
amounted to 0,39 /ha. Due to the war circumstances,the number of animals
has been reduced by 48,0 to 61,9 %.
Even small farms can provide for their existence by developinganimal
production. This is based on the statement that on a farmoccupying 4,4 ha
and growing one livestock unit/ha, aftersettling the costs, proceeds of
3500 DM /year can be obtained.However, the measures of the economic policy
must be encouragingto the farmers.

Summary:
Development of cattle-raising and sheep-farming demands an
intensive breeding of natural and artificial meadows, i.e. an
increase in the productivity and fodder quality by applying
ameliorative measures and mineral fertilization in particular.
This paper presents floral ecological, phytocoenological and
qualitative features of flora at the Agricultural Enterprise
Orahovica, fertilized and non-fertilized for one year in 1993,
respectively. Within the mixture of vegetation units of
associations, alliances and orders, the most frequent ones were
found to be the faciations of the forthcoming association
Arrhenatheretum elatioris alopecurosum and A. e. moenchiosum,both
belonging to the alliance Arrhenatherion Br. - Bl. 1925, theorder
Arrhenatheretalia Pawl. 1926, and the classMolinio-Arrhenatheretea
Tx.1937. The remaining regressive stages of associations (Bromo-
Cynosuretum, Serratulo-Plantaginetum), links (Trifolion
pallidi,Molinion,Deschampsion) and orders (Trifolio-Hordetalia,
Molinietalia,Deschampsietalia) of this class were rather
infrequent, having cover values of the characteristic species.
Flora (108 species) consisted of 81 strains, 30 families, 24
orders and classes of Liliatae and Magnoliatae. On the meadow
studied, the perenial species chemicryptophyts andEuropean-Asian-
sub-Mediterranean floral element were dominant. With regard tothe
agroecological soil conditions, the plant species have shown that
it had moisture ranging from medium one to moist, that it was
slightly acid and was medium poor to medium rich regarding the
nutrients.
The portion of unfavourable weed species (77,78 - 84,26%) of
the meadow brought about low green fodder and hay quality. This
indicates an insufficient application of ameliorative measures,
such as ground levelling, drainage and fertilization.

Summary: By special adjustments before and harvest, it is possible
to reduce the alfalfa seed losses in haeder and straw shaker to less than 1
%. With the increased speed of drum rotations, the seed losses at magnetic
separator are considerably ncrased, too. Seed purity, visible and invisible
seed injuries afect the level of seed losses. The highest germinability was
obtained with 750 drum rotations/minute. Germinability of seed depends on
the hard seed, the visible injuries, the seed purity and seed losses on the
magnetic separator a great deal. The visible and invisible seed injuries
ranged from 0,97 to 2,03 % and from 0,93 to 1,83 %, respectively.

Summary: Seed quality is an important factor in relation to the
arable land production,in particular for alfalfa and other leguminoses of
small-sized kernels.With the expansion of the production of alfalfa
seed,the presence of Cuscuta spp. becomes even more evident.In the region
of Slavonija and Baranja,its presence was recorded on apprroximately 40 %
plots under alfalfa,whereas in Istria,on the reddish soils,it was found on
about 80 % plots.In the production of alfalfa seed,Cuscuta spp. is a
quarantine weed species andtherefore as to be controlled both mechanically
and using herbicide preparations.This investigation included the
application of four herbicide preparations (Kerb 50,Cidokor,Pivot 100 E and
Aretit flussig) before the vegetation,after cutting the first growth in two
different quantities at the location of Osijek and Poreč (1988 and
1989).The results of tests in Osijek have shown that areas treated with the
Kerb 50 preparation (in mean over two years) had the lowest portion of
Cuscuta spp. seed (2,35%) whereas on the non-treated area its portion was
found to be 9,29 %.The applications of other herbicide preparations have
led to poorer results.The test carried out in the region of Poreč,the
region characterized by a different climatic environment,have shown
consedirably poorer efficiency of the preparations as compared to the
region of Osijek.The best result was achieved with the application of Kerb
50.The portion of the Cuscuta spp. seed was,however,53,63 %.Its portion
recorded on the non-treated area,averaged over two years,was 78,61 %.Other
herbicide preparations attained poorer results in the region of Poreč,as
well.

Summary: This paper presents the data on alfalfa seed losses during
processing,as well as on the seed quality after processing.The
investigation included seven seed lots classified according to the area of
its origin,the overall quantity amounting to 58.683 kg.The portion of seed
before processing ranged from 0,15 to 6,04 %.Depending on the origin,the
number of weed species ranged from 5 to 17.Among the weed seed that hardly
separates from alfalfa seed we have found:Cuscuta spp.,Rumex spp.,Plantago
lanceolata,Amaranthus retroflexus,Myosotis arvensis,Polygonum
lapathifolium,Setaria spp. and Sorghum spp..The machines for the
processingwere:air-screen cleaner and magnetic separator.During
processing,20,4% of alfalfa seed in mean was separated as useless
(air-screen cleaner-14,69%,magnetic separator-5,71%) and 10.211
kg,respectively,corresponding to the market value of approximately 40.000
DEM.The quantity of useless alfalfa seed was most affected by the presence
of weed seed that hardly separates from alfalfa (r=0,735),as well as by
percentage share of weed in the seed before processing (r=0,683).The
portion of ueseless alfalfa seed on the grading machine was affected by the
seed quantity (r=0,704) and the number of weed species the hardly separate
from alfalfa seed (r=0,523),whereas for the magnetic separator,it was
affected by the presence of weed seed that hardly separates from the seed
of alfalfa (r=0,723) and by the overall potion of weeds in the natural seed
(r=0,476).

Summary: Alfalfa in Croatia is sown from 3,85 to 4,35 % of arable
land according to year. Lands sown with alfalfa will not be increased in
the next period.Alfalfa yields are expected to increase per land
unit.Fertilization of home varieties in the production is poorly used
(about 40 %).Selection of varieties, application of proper techniques of
production and menagement, and use of genetic possibility should increase
at 65 to 70 %.The Republic of Croatia satisfies by 50 % its needs for
alfalfa seeds and is supposed to be autosufficient in the next 3-4 years.

Summary: Seed production of alfalfa has a long tradition in the
Republic of Croatia.In addition to the large experience,good
agri-ecological conditions and a wide range of the high-qualiti varieties
sown,the domestic production has not yet met the current needs at the
market and the seed quantities required are imported.One of the limiting
factor relating to the seed production is a large portion of weed species
in alfalfa fields,particulary of Cuscuta spp.,being a quarantine weed that
hardly separates from alfalfa seed during processing.To solve the
problem,we established field trials following the rendomized block-design
in four replications on two localities in two years.The trials were
established at the field of the Osijek Agricultural Institute on an Eutric
cambisol with 1,7 % vegetable mould,pH ranging from the neutral to poorly
acid reaction,a moderate active phosphorus and potassium content,as well as
on the field of the Agricultural Enterprise "Agrolaguna" Poreč,being the
red soil type with 0,87 % vegetable mould,a moderately acid reaction and
little active phosphorus and a slight portion of potassium content.The
efficiency of four herbicide preparations (Kerb 50,Cidokor,Pivot
100E,Aretit flussig) on the chemical control of Cuscuta spp. in alfalfa
fields in the fourth and fifth year was tested in two times of application
(Before groving period and after the first cut) and two different levels of
the preparations were applied.The objective was to compare the results with
the control plot.The herbicide preparations have attained various
efficiency coefficient with regard to the seed yield of Cuscuta spp. across
the years of the investigation,localities and times of applications.The
herbicide preparation Kerb 50 had the highest efficiency coefficient
(57,91% on average),whereas the lowest one was found after the application
of Pivot 100E (7,39% on average).In Osijek,the efficiency coefficient on
the preparation Kerb 50 was 78,85% with the average infestation with
Cuscuta spp. of 8,18%.The same data obtained in Poreč were 36,97% with the
average infestation by Cuscuta spp. of 73,47%.The time of herbicide
application had considerable effect on the efficiency coefficients
obtained.All preparations tested had higher coefficients when applied after
the first cut of alfalfa plants.The herbicide preparation Kerb 50,
considerable the most efficient one,had the efficiency coefficient after
the first and the second time of application amounting to 40,04% and
74,63%,respectively.The quantities of preparations applied did not affect
the level of efficiency coefficient obtained.The seed yield of alfalfa
ranged in years from 507,1 kg/ha on average (Osijek 1988) to 22,4 kg/ha
(Poreč 1988).The seedyields obtained were affected by climatic
conditions,the portion of Ciscuta spp. as well as the entire weed
flora.During the investigation,31 weed species from 2 classes,12 orders and
16 families were found.The following species of Cuscuta spp. were found and
determined on both localities:Cuscuta trifolii Bab. and Cuscuta campestris
Yuncker.According to the spectrum of life forms,the largest group found
belonged to the therophytes (58,06%),followed by chemychriptophytes
(35,48%).The geophytes were found to be freqent least.
