Effect of irrigation regimes, fertilizer quantity, and bush number conservation on cotton yield

Optimizing cotton yield is crucial for enhancing agricultural productivity, particularly in regions facing resource constraints. This study investigates the combined effects of different irrigation regimes, varying fertilizer quantities, and bush number conservation on cotton (Gossypium spp.) yield. Field experiments were conducted to assess how these variables influence key agronomic traits such as plant height, boll number, and overall yield. Three irrigation regimes (low, moderate, and high), three levels of fertilizer application (low, medium, and high), and bush number conservation strategies were evaluated. The results demonstrate that both irrigation and fertilizer levels significantly impact cotton yield, with moderate irrigation and optimal fertilizer application producing the highest yield, bush number conservation was found to improve resource utilization and increase yield per hectare. These findings provide practical insights for farmers aiming to maximize cotton productivity while conserving water and soil nutrients.
