THE PRODUCTIVITY OF CHICKPEA VARIETIES WHEN USING FERTILIZERS AND GROWTH STIMULANTS IN THE DRY STEPPE ZONE OF THE MIDDLE VOLGA REGION
The research results for 2016-2018 are presented. with an assessment of indicators of the structure of the crop, fodder merits, profitability. It has been established that the yield of chickpea is determined by the number of plants per meter, the number of beans per plant, as well as the weight of 1000 seeds. The largest seeds are formed by the Volzhanin variety with the application of fertilizers N<sub>12</sub>P<sub>52</sub> - 317.2-326.3 g. It was found that increasing the dose of fertilizers provides a significant increase in yield of 0.15 t/ha. The Volzhanin variety differs in the maximum yield on the background of the application of fertilizers N<sub>12</sub> P<sub>52</sub> with a yield of 2.04 t/ha and 2.00 t/ha when the crops are treated with Megamix Profi stimulants and a mixture of Aminokat + Raikat Development, respectively. It has been determined that the applied preparations Matrix Growth, Megamix Profi, Aminokat + Raikat Development contribute to the improvement of feed merits, the accumulation of digestible protein increases, and the yield of feed, feed protein units and metabolic energy increases. The Volzhanin variety with the accumulation of digestible protein 0.34 and 0.32 t/ha, feed units 2.43 and 2.40 t/ha, exchange energy 25.19 and 24.81 GJ/ha against the background of the use of fertilizers N<sub>12</sub>P<sub>52</sub> and treatment of crops, respectively, with Megamix Profi and Aminokat + Raikat Development. It has been established that the cultivation of chickpea varieties Privo 1, Volzhanin, Volgogradskiy 10 is economically feasible with a profitability of 38.4% to 112.6%. Sowing of chickpea Volzhanin is distinguished by the best profitability
