Impact of the main elements of the farming system on barley productivity in the south-west part of the Central region

Relevance Despite the available information on the effectiveness of a number of agricultural crops, there remains a discussion of the impact of the main soil treatment methods and the fertilization system in crop rotation on the yield of egg barley in the region. Therefore, the development of the most optimal combination of basic soil and fertilizer treatment for barley will allow to maximize the potential of plants and obtain high yields. Solving this problem remains an important task of farming. Methods In the long stationary field experience laid down at the Belgorodskiy Agrarian Scientific Center in 1987 in the south-western part of the Central Chernozem zone, the effects of the methods of basic soil treatment and various doses of organic and mineral fertilizers on the productivity of egg barley were studied during four rotations of grain-growing crop rotation. Results For an average of four rotations on absolute control variants due to natural soil fertility, barley yields were 2.45 t/ha. Single (NPK) 50 and double doses (NPK) 100 of mineral fertilizers increased yields by 36.7and49.8%, organic - by22.0 and33.5, respectively, and their interactions - by 49.4 and 70.6%. Deep soil treatment methods had little advantage over minimal treatment. In the production process, the share of soil treatment methods is 0.12%, organic fertilizers - 25.6%, and mineral fertilizers - 71.0%.
