Integrated Nutrient Management Impact Evaluation on French Bean (Phaseolus vulgaris L.) Progression and Productivity Gangetic Plain, Uttar Pradesh, India

Abstract

A field experiment was conducted to study the INM effect on different genotypes of French bean at the research plot of Krishi Vigyan Kindra-1, Kotwa, Azamgarh district, Uttar Pradesh, India during the two continual Rabi season of 2022-23 and 2023-24. Treatments were a combination of five different levels of fertilizers and vermicompost viz. 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) to fulfil the requirement of the recommended dose of fertilizers. Four genotypes of French bean i.e. Kashi Rajhans, Kashi Sampann, HUR-137, and HUR-15. Growth parameters data were recorded and analyzed at weekly intervals. Treatment (T2) and genotype Kashi Sampann observed a significant maximum plant height, number of primary branches, number of secondary branches, number of leaves per plant, leaf area index. Yield attribute i.e. maximum length of the pod the weight of green one pod, grains number per pod, the grain weight per pod, seed yield per plant, seed yield (23.04 q ha) and (22.58 q ha) straw yield (32.45 q ha) and (31.21 q ha), seed index. Maximum harvest index was achieved by T2 and genotype Kashi sampann. However, the maximum B:C ratio was achieved by T2 and genotype Kashi sampan. This shows T2 is more economically benefit to farmers than other treatments and genotype Kashi Sampann. Treatment (T2) attributed to better nutrient availability, improved soil properties and provided sustained nutrient release. It might be concluded that Kashi Sampann has better potential for by means of it as an alternate cultivar/ genotype for the zone of Gangetic plains and could be applied to enhance French bean productivity and production.
