Kravchenko V. Optimization of elements of technology of cultivation of spring wheat in southern forest-steppe of right-bank of Ukraine

The results of research about influence of sowing, planting, of predecessors on yield and grain quality of spring wheat in conditions of forest-steppe of right-bank of Ukraine. Features field germination of seeds, growth and development of aboveground parts of plants, the formation of leaf surface, photosynthetic potential of crops, net photosynthesis productivity, dynamics of accumulation of wet and dry mass, forming the main elements of the structure and yield of spring wheat depending on the elements of agricultural technologies. Economic and energy efficiency of cultivation of spring wheat. Learned that in the right-bank of forest-steppe of Ukraine on ashed for 4.0-5.0 t / ha of grain of spring wheat with good baking performance Vitka Type varieties should be sown in the I-II decade of April, the pace of Sowing 4,000,000 units / ha variety type 3 collective - in early April, a seeding rate of 5 million / ha after soybean. In the case of spring wheat sown after maize seed varieties of all types required in early April, a seeding rate of 5 million units / ha.
