Abstract
Cotton is an important filamentous plant used as a raw material in textile production. The yield of cotton depends on the variety of Cotton and environmental conditions, particularly nitrogen fertilizer, which is crucial for growth and increasing silk production. Effective production factors include appropriate fertilizer use and proper management to maximize plant efficiency. Therefore, a study of the effect of nitrogen fertilizer on cotton yield and fiber quality was grown on the Wang Hai soil series. The experimental design was a Randomized Complete Block Design (RCBD) with 4 replications, consisting of 5 treatments: T1 Nitrogen control, while T2-T5 applied nitrogen fertilizer rate at 0.5, 1.0, 1.5, and 2.0 times of soil. The recommended rate was determined based on soil analysis. The results demonstrated that nitrogen fertilizer significantly increased the height, yield, yield components, and quality of cotton fibers in advanced cotton varieties compared to no fertilizer, with statistical significance. Additionally, applying nitrogen fertilizer at 0.5 times of soil at the recommended rate provided the highest economic returns and yield for these advanced cotton varieties. Therefore, to produce economically viable, high-yield advanced cotton varieties, it is advisable to conduct soil analysis before planting and apply nitrogen fertilizer at a rate of 8-8-16 (N-P2O5-K2O) kg/rai.
