The objects of the study were hybrids: F1 Moy general, F1 Pafos and F1 Pompeo with the complex application of mineral fertilizers, water-soluble fertilizer, Solution and treatment of seeds and crops with the Energia-M growth regulator for the planned yield of 50, 70, 90 t / ha. The purpose of the study is to develop a set of elements of the technology for the cultivation of sweet peppers, which, while maintaining the calculated water (75-75-75% of HB - a constant irrigation regime and 70-80-75% HB – a differentiated irrigation regime) and nutrient regimes, obtain the planned yield of up to 90 tons / ha of high quality vegetable products. In accordance with the purpose and objectives of the work, our experiments were laid in the subzone of light chestnut soils in 2011-2016 (Gorodishchensky district of the Volgograd region, IP «Zaitsev V.A.»). The productivity of sweet peppers depended on the introduction of optimal mineral nutrition and irrigation regime. The most adapted hybrid is the F1 Pompeo. In the variant N235P140K130 + Rastvorin + Energy-M, the increase was about 34 t / ha (planning 50 t / ha), in the variant N300P180K165 + Rastvorin + Energy-M - about 21 t / ha (planning 90 t / ha). The proposed combination of yield factors allows saving water resources and partially replacing mineral fertilizers with more profitable and safe water-soluble fertilizers. A high economic effect was obtained from the production methods we proposed in the conditions of the Lower Volga region on the F1 Pompeo sweet pepper hybrid (N300P180K165 + Rastvorin + Energy-M) with differentiation of the irrigation regime (return on production costs - 6.8 rubles).
Key words: irrigation regime, mineral fertilizers, water-soluble mineral fertilizer, sweet pepper, increased productivity, environmentally friendly products
