Effect of Drip Irrigation and Mineral–Micronutrient Fertigation on Yield and Agrobiological Indicators in Cucumber Cultivation
Abstract
This study evaluated the agrobiological efficiency of mineral and micronutrient fertigation in cucumber cultivation under drip irrigation conditions. The experiments investigated the effects of applying NPK fertilizers at different application rates and growth stages, as well as their combination with micronutrient fertilizers, on the growth, development, and yield of cucumber. The results demonstrated that the distribution of mineral fertilizers according to phenological growth stages and their combined application with micronutrients improved nutrient uptake by the plants. The highest agrobiological and economic efficiency was achieved in the treatment where the scientifically recommended NPK rate was applied in combination with micronutrient fertilizers. It was also established that even with a partial reduction in the rate of mineral fertilizers, high yield and production efficiency could be maintained through the use of micronutrients. The findings provide a scientific basis for improving resource-efficient, environmentally sustainable, and highly effective fertigation systems for cucumber cultivation.
