The purpose of the research was to study the effect of planting time on the formation of productivity of Hungarian sainfoin when grown for green forage. Methods are field, laboratory, statistical, correlation and regression relationships. Research results. It is established that under uneven humidity and high temperature regime in the year of sowing, Hungarian sainfoin formed two yields under spring planting date and one yield under summer planting date. In the second and third years of growth, no significant effect of the planting date on the stages of organogenesis of Hungarian sainfoin was found, where the maturity of the herbage was reached simultaneously. Productivity of Hungarian sainfoin was only conditioned by hydrothermal conditions, where the yield of green mass averaged 45.9—49.6 t/ha with crude protein content of 1.58—1.73 t/ha. At the same time, the highest dry matter yield of 10.25 t/ha and crude protein of 1.73 t/ha was provided by agrophytocenosis when sown on April 12. The productivity index of Hungarian sainfoin in the first year of life was determined, where the highest indicator was obtained during the early spring sowing period (29.04) – 7.85 kg/ha of dry matter per 1 hour of light day, whereas for the recommended summer sowing period was 1.13 kg/ha, or 6.9 times lower. The correlation equation between dry matter output, duration of daylight and the sum of precipitation from full shoots to the beginning of flowering in the first year of life is described. It is found that with increase of precipitation by 1 mm the dry matter output increases by 1.53 % and there is a tendency increase with increasing the length of daylight by 1 minute. Conclusions. It has been established that on gray forest soils of the right-bank Forest-Steppe, over two years of intensive use of the grass stand, regardless of hydrothermal conditions, Hungarian saifoin provided a stable forage productivity when sown in spring. Thus, dry matter yield was 9.38—10.25 t/ha with crude protein content of 1.58—1.73 t/ha. In particular, as for summer planting date, July 20 appeared to be the most effective planting date, which provided dry matter yield of 9.78 t/ha with crude protein content of 1.61 t/ha.

Abstract This study highlights the effect of drought and ambient temperature on performance and herbage quality of legume monocultures and grass-legume mixtures. In a field experiment, the total dry matter yield, seasonal pattern of dry matter yield distribution, content of crude protein and crude fibre of monocultures of red clover and alfalfa and grass-legume mixtures were investigated during two consecutive dry years (2011-2012). Alfalfa cultivars Kamila and Tereza grown as monocultures or as mixtures with Festulolium braunii (cultivar Achilles) outperformed the red clover cultivars Fresko and Veles and provided a well-balanced total and seasonal dry matter yield during both years. Across all experimental years, crude protein content was significantly higher at alfalfa monocultures and mixture when compared with clover monocultures (P < 0.05). However, considerable lower content of crude fibre at clover monocultures in comparison with alfalfa ones was found. Responses of nutritive parameters of both legume species to weather variables were different. Crude protein content in red clover was independent of rainfall and temperature. In contrast, the crude fibre content correlated with temperature whereby the alfalfa monocultures showed stronger correlations (P < 0.05) than red clover monocultures.

The research was carried out in the Eastern Mediterranean Agricultural Research Institute-Hacı Ali location with 4 replications according to the randomized block trial design in 2013-2014. 13 public and 1 private sector maize variety were used as material in the trials. According to the results of the analysis, it was determined that the maize varieties examined showed statistically significant differences in plant properties, dry grass and silage quality. Average plant height, number of leaves, leaf ratio, stem diameter, number of cob, stem ratio, cob ratio and green grass yield were 249.9 cm, 12.97 plant/piece, 19.24%, 22.08 mm, 0.93 plant/unit, 38.40% and 4,251.57 kg/da respectively. According to the analysis, it was observed that the average crude protein content, ADF ratio, NDF ratio, crude ash content, digestible dry matter ratio, crude protein yield, dry matter rate, dry matter yield and hay yield were 8.80%, 34.91%, 59.7%, 7.2%, 61.7%, 993.9 kg/ha, 29.4%, 11,640 kg/ha 12,570 kg/ha in dry grass, respectively. For the silage of varieties, the average crude protein content, ADF ratio, NDF ratio, pH, digestible dry matter rate, dry matter ratio, crude protein yield and Fleig score were 8.22%, 29.27%, 50.48%, 3.57, 66.1%, 28.14%, 926 kg/ha and 118.35, respectively. Burak, Sasa 1 and Ada 334 genotypes performed better in terms of green yield per hectare (53,650, 50,290 and 45,630 kg/ha) and dry matter yield (14,710, 12,810 and 12,410 kg/ha). These varieties can be recommended to producers as silage maize varieties under second crop conditions in Çukurova region of Turkey.

In a field experiment the development of dry matter yield and forage quality of the catch crop Vicia sativa L. compared with Trifolium resupinatum L. was investigated and the suitability for cultivation in a mixture with Lolium multiflorum ssp. gaudinii (Parl.) Schinz et Keller was tested. The legumes and mixtures sowed in early July or August, respectively, were harvested at different dates from early September until late October/early November. The sowing date had the greatest impact on dry matter yield, crude protein content and net energy for lactation (= NEL). Vicia sativa yielded more dry matter than Trifolium resupinatum, especially at low temperatures and under short-day conditions. At late sowing Vicia sativa should be preferred to Trifolium resupinatum due to a better stability of yield. Vicia sativa had a&nbsp;higher crude protein content but a lower NEL than Trifolium resupinatum. In a mixture with Lolium multiflorum the differences in energy concentration between late sowed legumes were less distinct. In view of NEL, Trifolium resupinatum is superior at early sowing, whereas late sowed mixtures of Vicia sativa and Lolium multiflorum might enable it to feed fresh forage of acceptable quality until early November and in that way to save it for winter feeding and eliminate expensive sources of crude protein.

Fluazifop-P, applied in the spring or fall and pronamide, applied in the fall only, reduced quackgrass infestation in established alfalfa and increased the dry matter yield of alfalfa. Herbicides did not improve alfalfa in vitro digestibility or crude protein content. Average residues of fluazifop-P in alfalfa treated with rates of 0.25 or 0.5 kg ai ha–1, were 0.1 mg kg–1when harvested 280 d after application, and 0.06 mg kg–1when harvested 295 d after application. Average residues in alfalfa harvested 41 and 55 d after application were 0.13 mg kg–1and 0.1 mg kg–1, respectively, with a 0.25 kg ha–1treatment and 0.19 mg kg–1and 0.05 mg kg–1, respectively, with a 0.5 kg ha–1treatment.

In the soil and climatic conditions of the Right Bank Forest-Steppe, regardless of the action of abiotic and biotic factors during the growing season, high adaptability of alfalfa was established for different geographical origins, namely the natural zone of the Forest-Steppe, Polissya, Steppe Ukraine and Serbia. It was found that under the weather conditions of 2016 year alfalfa varieties reacted differently to changes in temperature and moisture during the growing season. It is important to note the effectiveness of phosphorus-potassium fertilizers applied directly to alfalfa coverless method of sowing. In the year of sowing, alfalfa formed a powerful herbage and provided two slopes with a yield of green mass at the level of 20,13-29,80 t/ha with a dry matter yield of 4,80-6,69 t/ha. For the second year of vegetation, alfalfa was carried out according to the regimes, which considered the phases of growth and development (budding, beginning of flowering and flowering). In the first mode of cutting management (all slopes in the budding phase) it is advisable to identify three varieties of Unitro, Nasoloda and Rosana, which provided a gross dry matter of 10,41-10,48 and 2,29-2,31 t/ha of crude protein. The productivity of alfalfa increased with late term cutting - at the beginning of flowering and a combination of slopes (3rd mode). The dry matter yield was 11,40-12,62 and 2,35-2,51 t/ha of crude protein (second regime) and the indicators increased under the third regime, especially dry matter 13,58-15,80 t/ha and decreased to 2,37-2,41 t/ha of crude protein. The increase in dry matter of the second mode increased by 9,5-23,1% and crude protein by 2,6-20,5%, and in the third mode of use of alfalfa it was 2,3-11,2%, compared to the mode of mowing the grass in the budding phase. During the third year of vegetation under favorable agroecological conditions for growth and development of alfalfa plants, the studied varieties provided four slopes regardless of the mode of use of grass with a dry matter yield of 15,43-20,58 and 3,21-4,02 t/ha of crude protein. During the second and third years of vegetation from the studied modes of use of alfalfa grass for fodder purposes, the highest yield of crude protein 5,27-6,53 t/ha varieties provided for the alienation of crops at the beginning of the flowering phase, which was on average 6,0-7,1% higher than when mowing all slopes in the budding phase and a combination of slopes in the phases of growth and development (3rd mode). Thus, in the conditions of the Forest-Steppe of the right bank on gray forest soils alfalfa, regardless of geographical origin, adapted to growing conditions and provided stable productivity indicators regardless of the regime of grass use with observance of elements of cultivation technology.

Forage Crops

The management of non-leguminous annual forage crops can affect dry matter (D.M.) yields, chemical composition, and nutritive (feeding) values largely because of the stage of maturity at which the crop is harvested. After studies for selecting high-yield forage oat varieties for a highaltitude tropical climate (Haile, 1976), it was considered necessary to look into the management of forage oats so that the time of harvesting for maximum forage and crude protein yield could be established.

Cutting Height

The interactions of three dates of initial cutting followed by one or two subsequent cuttings, three heights of cutting, and four fertilizer treatments on the dry matter yield, crude protein content, and crude protein yield of intermediate wheatgrass (Agropyron intermedium (Host.) Beauv.) were studied on irrigated land for 2 yr. Cutting on 15 June during the shot blade stage resulted in severe summer killing. Variation in height of cutting and N fertilizer levels resulted in differences in annual yields. On the basis of the 2-yr mean yield, however, these differences were masked by interaction of these factors with years. Crude protein content of the forage at cut 1 decreased with the deferment of the first cut, was not influenced by height of cutting, but increased with increases in N fertilizer. The yield of crude protein increased with increasing levels of N fertilizer and showed significant interactions for year × date of initial cutting × fertilizer and years × date of initial cutting × height of cutting. Split applications of N fertilizer showed no advantage over a single spring application in either year.

Yield And Quality

Maize is the very important silage source in the world. Timely harvesting ensure high maize forage yield and quality. Therefore, the study focused on the effects of four harvesting times (starting at the 12 August every 7 days) on yield and qualitative parameters of forage green mass of maize hybrid ZP 677. The experiment was set in Vojvodina Province, Serbia, during the 2013 and 2014 growing seasons. Plant height, stem diameter, number of leaves per plant, ear percentage, forage yield, dry matter content and crude protein content were higher, while stem percentage was lower in 2014 with favorable climatic condition. Forage yield, crude protein content, ADF and NDF decreased, while dry matter content significantly increased with delay in harvesting. The maize hybrid should be harvested when the milk line is three-quarter of the way down the grain that is in the third decade of August.
