Increasing the production of environmentally friendly high-quality vegetable products

Abstract

Abstract For the first time in the zone of chestnut soils, complex scientific studies of resource-saving methods for increasing the productivity of vegetable crops in an acutely arid climate by regulating physiological and biological processes during drip irrigation were conducted and a system for applying these methods was developed. Research in the experiment was carried out according to generally accepted methods. As research has shown, irrigation and the use of mineral fertilizers and a growth regulator to a certain extent affected the content of dry matter, vitamin C and raw fiber in the fruits of sweet pepper and other indicators. The maximum amount of dry matter was observed on the variant N300P180K165 + Rastvorin + Energy-M on the Pompeo F1 hybrid – 7.98 and 8.06%, respectively, according to irrigation modes. Indicators such as vitamin C, fiber and sugar content in fruits increased with the improvement of the nutritional and water regimes of sweet pepper growth. As the result of the variety study of vegetable crops of domestic and foreign selection, the best was the Pompeo F1 sweet pepper hybrid, which surpasses the standard variety of the Podarok of Moldova by 30.10 t/ha, on average for irrigation modes.
