Influence of inorganic fertilizers on cotton crop yield in saline soil
The crop yield of each cotton variety depends on its biological properties and on external factors, such as water regime and the amount of mineral nutrition. In 2016, experiments were conducted with a promising cotton variety Bukhara-102 zoned on takyr soils located in the territory of the Kashkadarya experimental station in the Kashkadarya region of the Research Institute of breeding, seed and agricultural technology of cotton growinf. Three variants of sites with different degrees of salinization were determined: non-saline, low and medium saline. To activate the development process, various combinations of mineral nutrition and the time of their introduction were used. The best option among all studied was found to be mineral fertilizers with the standard N-160, P-100 and K-70 kg/ha. Received the highest economic efficiency.
