Optimal combination of canopy management and planting density for yield enhancement in late-sown cotton

BACKGROUND: Cotton growers often face reduced yield and fiber quality after wheat harvest due to the shortened growing season. The delay in wheat harvest is due to a number of reasons, such as labor unavailability, weather, and machinery constraints. The optimal combination of canopy management and planting density may help in mitigating these problems in late-sown cotton. METHODS: ) and six canopy management techniques, pruning, manual topping, chemical topping, and their combinations. RESULTS: Cotton growth, yield, and fiber quality were greatly influenced by these techniques. Chemical topping plus pruning increased sympodial branches up to 38%, and seed cotton yield at higher planting density. In contrast, manual topping plus pruning outperformed other methods in improving fiber uniformity and strength. CONCLUSIONS: The results showed that a combination of chemical topping plus pruning enhances seed cotton yield, whereas manual topping integration with pruning improved fiber quality. Finding suggests the importance of selecting an optimal combination according to production needs under a cotton wheat cropping system in late sown conditions.
