Abstract
The results of the 2016–2017 studies are presented. Indicators of the crop structure, productivity and fodder values of chickpea varieties (Privo 1, Volgogradsky 10, Volzhanin) are determined. Different methods of crops treatment with growth stimulants Growth matrix, Megamix Profi, Aminokat + Raikat Development are described. The multifactorial experiment included two options of mineral nutrition (without and with fertilizers N12P52 (factor A); three varieties of chickpeas: “Privo 1”, “Volzhanin”, “Volgogradsky 10” (factor B); two options of vegetation treatment: without and with treatment using Growth Matrix, Megamix Profi, Aminokat + Raikat Development (factor C). The studies have shown that all treatment options f increased productivity of chickpeas and crops quality. The maximum yield was obtained by applying N12P52 for Volzhanin variety treated with Megamix Profi and Aminokat + Raikat Development (2.19 t/ha and 2.16 t/ha with a dry matter of 1.97-1.95 t/ha, digestible protein of 0.36-0.33 t/ ha and an exchange energy yield of 27.10-26.90 GJ/ha, respectively).
Highlights
The problem of insufficient amount of vegetable protein in feed is crucial
Its proteins are balanced by the amino acid composition
The research objectives are as follows: - to assess productivity of different varieties of chickpeas depending on the use of Growth Matrix, Megamix Profi, Aminokat, Raikat Development at different levels of mineral nutrition; - to assess the crops structure and the nutritional value of chickpeas
Summary
The problem of insufficient amount of vegetable protein in feed is crucial. This problem can be solved by obtaining protein from legumes. They have a high feed value and improve the use of animal feed of other lowprotein crops [1,2,3,4]. Among all the leguminous crops, chickpeas are the most drought- and heat-resistant due to a high content of bound water in leaf tissues, their xeromorphic structure, pubescence, and the presence of organic acids [5]. Its proteins are balanced by the amino acid composition. They are the best by the number of basic essential amino acids (methionine and tryptophan)
