Effects of Integrated Nutrient Management and Vermicompost on Genotypes of French Bean in Phenology and Yield under Gangetic Plain

Abstract

The field experiment trial was carried out at the research plot of Krishi Vigyan Kindra-1, Kotwa, Azamgarh, Uttar Pradesh India during the winter season of 2022-23 and 2023-24. The Split Plot Design was laid out for experimental research plot for 20 treatments with three replications of five combinations of fertilizers and vermicompost, T1 (100% NPKS + 0% VC), T2 (75% NPKS + 25% VC), T3 (50% NPKS + 50% VC), T4 (25% NPKS + 75% VC) T5 (0% NPKS + 100% VC), and four genotypes of French bean i.e. Kashi Rajhans, Kashi Sampann, HUR-15, and HUR-137. The study's primary goal was to evaluate the effects of varying fertilizer and vermicompost levels on various French bean genotypes (Phaseolus vulgaris L.).In this investigation, treatment (T2) 75% NPKS through fertilizers + 25% vermicompost, and cultivars Kashi Sampann the results were non-significantly on phenology but growth and yield parameters achieve significantly more plant height (44.44 cm), number of primary branches (4.08), secondary branches (8.12), leaves per plant (51.71), leaf area (2966.17 cm2), leaf area index (4.37), Yield and same important yield attributing variables i.e. pod length (8.51 cm), the weight of one pod (6.49 g), and green pod productivity (yield 169.09 q ha-1), straw yield (32.45 q ha-1), seed index (24.72 gm), were significantly higher than other treatments. Harvest index (41.46 %) and B:C ratio (3.30) of treatment (T2) and cultivar Kashi Sampann showed that French beans might be beneficiary for farmers and soil healthier. Treatment (T2) attributed to better nutrient availability, facilitated by the combination of fertilizers and vermicompost, enhanced soil properties and provided a sustained nutrient release. Kashi Sampann has good potential for adoption as an alternative genotype for the Gangetic Plains region and could be utilized to increase French bean production, according to the results collected.
