Sustainable Nutrient Recycling through Non-Leguminous Weed Manures: Residual Effects on Growth of Lablab purpureus L.
Year: 2026
Type: article
Abstract: Sustainable nutrient recycling using locally available bioresources is a key component of green technology and climate-resilient agriculture. Non-leguminous weeds, generally regarded as agricultural waste, can be effectively utilized as organic manures to enhance soil fertility and crop performance. The present study evaluates the residual effects of non-leguminous weed manures on the growth of Lablab purpureus L., an important pulse and fodder crop. Weed biomass was incorporated into the soil prior to sowing, and growth parameters including plant height, number of leaves, leaf area, and fresh and dry biomass were recorded during the cropping period. The results revealed that residual application of weed manures significantly improved vegetative growth and biomass accumulation of Lablab purpureus compared to untreated control plots. Improved soil organic matter and sustained nutrient availability due to gradual decomposition of weed biomass were found to be responsible for enhanced crop growth in the succeeding crop. The findings highlight the potential of non-leguminous weed manures as an eco-friendly nutrient management strategy that promotes sustainable agriculture, reduces reliance on synthetic fertilizers, and contributes to climate resilience
