Pavlenko H. Formation of soybean yield depending on growing technology elements in Right-bank Forest-steppe

The object is the processes of growth, development and yield formation of soybean varieties of different maturity groups depending on the conditions of mineral nutrition, treatment of seeds with bacterial drug and microfertilizer. The aim of the researches was to determine the patterns of formation of yield and seed quality of soybean varieties of different maturity groups depending on the dose and timing of fertilizer application, treatment of seeds with bacterial drugs and microelements in conditions of Right-Bank Forest-Steppe of Ukraine. The methods used - field; measuring, weighing, laboratory, comparative-calculated; statistical and mathematical. Based on the results obtained it has been improved and implemented into production the technology of soybean varietal growing, which provides 2.8-3.3 tons of seeds per hectare and 11087-14802 UAH of net profit. Implementation of scientific developments was carried out in 2011 in peasant farm enterprise "Nyva" of Bobrovytsia region, Chernihiv Oblast on the area of 15 ha and in 2012 on the area of 20 ha, in 2013 in LLC "Vinnychchyna" of Orativ region, Vinnytsia Oblast on the area of 30 ha.
