Effect of new forms of fertilizers and growth regulators on photosynthetic activities of crops, yield and barley grain quality of feed purpose varieties

Development of new forms of complex fertilizers is a sore issue in many countries of the world. Compared with simple fertilizers, these forms provide a balanced ratio of nutrients for crops, increase economic efficiency due to reduction of application cost. The paper presents data on effect of new complex fertilizer with trace elements for main application in soil, micronutrients (Adobe Copper, complex fertilizers for foliar application (Nutrivant plus, Crystallon), plant growth regulators (Ecosil and Fitovitall), micronutrients with plant growth regulators (Elegum-Copper, MicroStim-Copper L) on the photosynthetic activity of crops, yield and quality of feed purpose barley. Promising variants of fertilizing system using set of agrotechnical techniques in technology of feed purpose barley varieties cultivation are proposed. Effect of various prospective fertilizers, micronutrients, plant growth regulators (both domestic and foreign) on photosynthetic activity of crops, yield and grain quality of feed purpose barley has been determined. Complex effect of the studied preparations on yield and grain quality was determined. Improvement of crop products based on development of efficient resource-saving farming systems and environmentally friendly technologies for production will contribute to formation of efficient and competitive agroindustrial production, ensuring the country’s food security and entry into world food markets.
