Influence of cultivation technology on the yield of winter wheat

Abstract

A comprehensive study has been carried out on the influence of technological methods of growing winter wheat on the process of formation of the above-ground mass of plants in the conditions of the forest-steppe of Ukraine. Crop rotation was carried out with two predecessors: black fallow and spring barley at a seeding rate of 3 and 5 million viable seeds/hectare. Evaluation of the intensity of plant development in the initial period of vegetation (measurement of absolutely dry weight of 100 plants 15 and 30 days after the emergence of full seedlings) was recorded in winter wheat plants in black fallow crops. The largest above-ground mass of the plant was formed 30 days after the emergence of full seedlings. A direct correlation was established between the amount of productive moisture in the soil layer of 0-25 cm and the period of emergence of winter wheat seedlings. The highest level of winter wheat yield was obtained for black fallow 3.46 t/ hectare when sown in the second decade of October.
