Efficiency of peas Premier cultivation depending on applied mineral fertilizers and sowing rates

Purpose: to study the efficiency of cultivation variety Premier peas on ordinary chernozem, depending mineral fertilizers and seed sowing rates. Materials methods. The experience was laid fields Department Agriculture Crop Production Federal Rostov Agricultural Research Centre. objects research are elements pea productivity, yield protein content in grain, applied seeding rate. Statistical analysis data, records observations were carried out according method B. A. Dospekhov. Results. rate influences el-ements productivity. An increase 1.2 million seeds/ha leads a signifi-cant reduction number formed beans, seeds bean, decrease grain weight. Fertilizers did not have significant effect introduction phosphorus potash peas. combined application nitrogen, potassium sig-nificant when sown 1.0 seeds/ha. Nitrogen do impact helps grain. maximum obtained N₆₀ variant, amounting 24.8 %. responsiveness introduced depends At optimal seeds/ha, highest payback variant with 20 kg a. i. potassium, 7.7 kg/kg Conclusions. best results which pro-vides an opportunity get conditional net income high profitability pro-duction. 41.7 thousand rubles/ha observed option P₄₀K₄₀, while production 139.39 %, cost 12.5 rubles/t.
