Efficiency of the main application of fertilizers and top dressing of eggplant under drip irrigation on ordinary chernozems of the Rostov region

Relevance. Fertigation is the application of fertilizers, in which nutrients are dissolved in water for irrigation. This method is relevant when growing eggplant in the Rostov region, allowing effective use of fertilizers, since nutrients enter directly into the roots of plants, which eliminates their loss to evaporation or weathering. During fertigation, there is no need to carry out separate procedures for fertilization and irrigation, operations are combined into one, which reduces time and costs. The Rostov region is characterized by variable climatic conditions, including drought and strong winds. Fertigation ensures uniform and constant nutrition of plants, allowing them to better adapt to weather conditions, and can help increase yields by optimizing plant growth and development conditions. Material and methodology. In the conditions of the Rostov region, on ordinary heavy loamy chernozems, studies were conducted on the cultivation of eggplant on different backgrounds of the main application of mineral fertilizers in calculated doses before planting and using root fertilizing with complex fertilizers with trace elements with irrigation (fertigation), as well as leaf fertilizing with organomineral fertilizer Arksoil during the growing season.
