Abstract
Efficient weed management is central to improving nutrient use efficiency and sustaining soil fertility in vegetable cropping systems.This study evaluated the impact of various weed control strategies, including black polythene mulch, integrated chemical approaches, and manual weeding, on nutrient uptake by okra (Abelmoschus esculentus) and nutrient depletion by weed flora under field conditions.Results revealed that black polythene mulching significantly reduced weed biomass and nutrient removal by weeds across all stages of crop development (15, 30, 60, and 90 days after sowing).It also enhanced nitrogen (N), phosphorus (P), and potassium (K) uptake by the okra crop, particularly during the critical early growth stages.Among all treatments, black polythene mulch and the weed-free check consistently recorded the lowest nutrient losses and the highest crop nutrient assimilation, while un-weeded control plots exhibited the greatest nutrient depletion, confirming the competitive dominance of weeds under unmanaged conditions.The integration of herbicidal treatments with inter-cultivation further improved nutrient conservation but was marginally less effective than polythene mulch.These findings underscore the efficacy of black polythene mulching not only as a physical weed barrier but also as a nutrient management tool that fosters sustainable okra production.The study advocates for its adoption as part of integrated weed and nutrient management strategies to enhance yield potential and agro-ecological resilience in vegetable-based systems.
