The combined irrigation of sweet pepper

Abstract

The advantages of drip irrigation of many agricultural crops are well known, but it does not allow to regulate the phytoclimate in the “environment-plant” system, which is especially important for the conditions of the hot and dry climate of the Republic of Dagestan. Currently, the efficiency of fine sprinkling on the background of drip irrigation was insufficiently studied, as questions remain the combined effect of irrigation on crop productivity in real climatic conditions on the effectiveness of combination with other agronomic techniques, etc. Experimental studies were conducted on the experimental field of the Department of Agriculture, Soil Science and Land Reclamation in the educational and experimental farm of the Dagestan State Agrarian University. The main purpose of the research was to determine the parameters of the combined irrigation technology, its effect on the microclimate of the irrigated field and the phytoclimate of plants, as well as the productivity of sweet pepper. As the result of experimental studies, it was found that the use of a combined irrigation system (drip irrigation + fine sprinkling) when cultivating sweet pepper allows to obtain an additional 9.4 t/ha of marketable products by optimizing the growing conditions.
