Agrotechnology of sweet pepper cultivation in the zone of light-chestnut soils in Caspian Sea region during irrigation
They have been identified the varieties and hybrids of sweet pepper, most promising for soil and climatic conditions in the north of the Astrakhan region, that have high adaptive capabilities and significant potential yields in creating an optimal level of mineral nutrition and water consumption. In the field two-factor experiment, there were conducted phenological observations, taking into account water consumption and biological yields and were determined crop structure, the weight of the commodity fruit and the marketability. Based on the results of production costs and biological yields, it was determined the economic efficiency of the use of mineral fertilizers in the cultivation of sweet peppers during drip irrigation in the zone of light chestnut soils of the Caspian Sea region.
