Productivity and indicators of quality of soybean seeds under different elements of cultivation technology on the irrigated lands of the south of Ukraine

In the conditions of the south of Ukraine on the irrigated lands was studied the effect of different irrigation regimes, methods of primary tillage and dates of phosphogypsum application on productivity and quality of soybean grain. The application of ameliorant to the soil surface in the autumn after the primary tillage and to the thawed soil in spring with water-saving irrigation regime regardless of the tillage method contributed to the formation of soybean yield, yield of oil and protein per area unit at the level of the recommended technology of its cultivation.
