Abstract

Nepal's pursuit of sustainable food production and rural livelihoods faces challenges amid evolving environmental pressures. Okra (Abelmoschus esculentus) cultivation, integral to Nepalese agriculture, demands innovative approaches to enhance productivity while minimizing environmental impact. This study investigates the efficacy of varied organic fertilizers on okra growth and development, aiming to identify sustainable alternatives to chemical fertilizers. The research was conducted at the G.P. Koirala College of Agriculture and Research Centre in Sundarharaicha, Morang, Nepal, from June to August 2023. A Randomized Complete Block Design (RCBD) with eight treatments replicated three times was employed, including recommended NPK dosage and various organic sources. Observations on plant height, primary branches, pods per plant, pod length, diameter, weight per pod, and yield per plant were recorded. Statistical analysis revealed significant variations among treatments. The highest yield was obtained with the recommended NPK dosage (108.84 g/plant), closely followed by biofertilizers like 100% mustard cake (103.70 g/plant) and goat manure (104.28 g/plant). The lowest yield was observed in the control group (76.99 g/plant). Notably, NPK fertilizer consistently outperformed organic alternatives in promoting okra growth and yield. However, among organic fertilizers, mustard cake and goat manure emerged as promising alternatives, showcasing comparable results to synthetic fertilizers. These findings underscore the importance of balanced nutrient management in optimizing okra productivity. Future research should explore integrated nutrient management strategies, combining organic and synthetic inputs, to enhance sustainability and resilience in Nepalese agriculture.
