The article presents the results of the laboratory investigation of the influence of high temperatures on water regime of red currant in Institute of Fruit Selection. It shows the dependence of water loss by leaves on the phenophase of plant development. High water loss by leaves occurs during the phase of ripening berries (July). Low water loss is noted during the active growth of shoots (June). Red currant genotypes: «Valentinovka», «Bayna» have a high percent of water loss in June and July. Genotypes «Shedraya», «Gollandskay krasnay», «Orlovchanka», «Dar Orla», «Selyanochka», «Osipovskay», «Belka» and «Jonker van Tets» have a low percent of loss water. The loss of water at the temperature shock is the important protective mechanism from over heat and death of plants. The results of the investigation of a degree of water restoration by red currant leaves in the periods of berry ripening and active growth of shoots are given. The most part of genotypes of red currant leaves have a high percent (>50%) of water restoration. Genotypes «Selyanochka» ,«Orlovchanka», «Dana», «Shedraya», «Belka» have a more 100% of water restoration. On the ground of the obtained results the following genotypes: «Belka», «Selyanochka», «Gollandskay krasnay», «Shedraya», «Orlovchanka», «Dar Orla», «Osipovskay» and «Jonker van Tets» are mostly heat resistant.

Наведено результати досліджень впливу строків сівби та глибини загортання насіння на фотосинтетичну продуктивність посівів сорго цукрового сорту Силосне 42 в умовах центральної частини Лісостепу України. Зокрема, наведено дані стосовно площі асиміляційної поверхні листків рослин, фотосинтетичного потенціалу, чистої продуктивності фотосинтезу, а також дані двофакторного дисперсійного аналізу. Встановлено, що у разі сівби сорго цукрового в другій декаді травня (третій строк сівби) на глибину загортання насіння 4–6 см рослини розвивались краще, і за цих умов отримано максимальні значення показників фотосинтетичної продуктивності порівняно з іншими варіантами досліджень. Тому ми рекомендуємо третій строк сівби та глибину загортання насіння 4–6 см для вирощування цієї культури в зазначеній зоні

It is determined that crop cultivation systems (continuous culture and its interruption by crop rotation links with different fertilizer backgrounds) influence the productivity and economic efficiency    of tomato and cucumber cultivation under rainfed   conditions in Right-Bank of Forest-Steppe zone in  Ukraine. Reported calculations show the increased level of profitability of the continuous crop growing in case  of interruption by annual crop rotation link against the background of mineral nutrition, but additional organic fertilizers allow to get more profit per unit area.

Results of studying morphoagrobiological characteristics and properties of new high-protein variety of soft winter wheat Natalka are presented. It is determined that this variety successfully combines high natural productivity potential with genetically inherited the highest grain quality and positive reaction of protein accumulation. It can be classified as superstrong wheats by qualitative  properties. It belongs to intensive varieties, has higher winter and drought hardiness. This variety is characterized by wide agroecological plasticity. To realize genetic potential of productivity and qualitative properties variety sowings should be placed after the best forecrops with high soil fertility creation, implementation of intensive technologies and sowing at the end of optimal time for appropriate agroclimatic zones.

Elements of energy-saving technology of table beet seed production (variety type of Bordeau) in the Eastern Forest-Steppe of Ukraine were improved, they include method of irrigation (drip irrigation, HB 70–65%), fertilizing (locally N 15 P 30 K 60 + N 15 ), fertigation (stage of 3–4 true leaves, bundle ripeness, the beginning of stooling and flowering), the use of standard mother roots 61–100 mm in diameter along with mother rootsstecklings 41–60 mm in diameter that increase average yields according to the size up to 1,89 t/ha. It is found that the application of micronutrient mixture of Zn + B + Mo in one term and mixture of Zn + B in two terms was the most effective.

Scientifically validated items of growing technology disclosed for cos lettuce marketable products in the conditions of Forest-Steppe of Ukraine. Impact of environmental factors onto growth and development of Lactuca sativa var. longifolia L. plants. Sowing terms established for the seed of cos lettuce at field-seeded growing. Development parameters are quoted for plant productivity indices and marketable product indices for cos lettuce of national and foreign breeding. According to VCU characteristics a  typical model has been designed for the cos lettuce indices of suitability for dissemination in Ukraine.

Results of studying morphoagrobiological characteristics and properties of a new variety ofsoftwinterwheat Nyva Kyivschyny are presented. It is determined that it has high genetic productivity potential, belongs to intensive variety type of universal use, is characterized by high winter and drought hardiness. This variety realizes its natural potential in a greater degree in case of growing after the best forecrop, at high soil fertility, with intensive agrotechnologies implementation and sowing at the end of the optimal time for appropriate agroclimatic zones.

Yield of modern varieties of valuable fodder crop lucerne is quite low - 0.2 - 0.3 t / ha. The reason - lack of cross-pollination due to the lack of insect pollinators. Under these conditions, the highest seed production plants are prone to selfpollinate. The results of the study of 26 new selffertile samples of alfalfa own selection. It was shown that 15 samples for seed yield higher than standard - grade Jaroslavna. The herbage yield of only four samples was lower than in the standard. The dry matter content of all samples was high - 22,1-25,5 %. The results obtained are allowed to select in hotbed of pre-strain testing samples with high levels of self-fertility, seed yield 0,24-0,29 t/ha, herbage for three mowing - 63,2-67,7 t/ha, high dry matters content, which will be used in future breeding process
