Abstract:
During the summer of 2021-2022, a study at the Organic Farming Research and Training Centre examined the effects of organic manure and biofertilizers on the growth and yield of Indian spinach. The experiment revealed significant effects using a Factorial Randomized Block Design with three bio-fertilizers (Azotobacter, PSB, Azospirillum) and two organic manure FYM levels. Azotobacter had the shortest germination period (5.26 days), while Azospirillum had the best growth characteristics. The 100% RDN via FYM treatment outperformed in all growth and yield parameters. Azospirillum had higher yield characteristics such as fresh weight of leaves (21.91 g) and total yield per hectare (20.38 t). Azospirillum had the highest available nitrogen according to soil analysis. Economic analysis revealed that Azospirillum and the 100% RDN through FYM treatment resulted in higher returns and benefit-cost ratios. In conclusion, Azospirillum bio-fertilizer and 100% RDN through organic manure FYM exhibited superiority in the growth and yield of Indian spinach compared to other treatments.
