Effect of phosphorous levels and different biofertilizers on growth and yield of French bean (Phaseolus vulgaris l.) under Patiala region

Abstract

The field experiment entitled “Effect of phosphorous levels and different biofertilizers on growth and yield of French bean (Phaseolus vulgaris L.) under Patiala region” was carried out at the Campus for Research and Advanced Studies, G.S.S.D.G.S. Khalsa College, Patiala during the Rabi season of 2022-2023.The experiment was laid out in factorial randomized block design with four levels of phosphorous (P1: 40, P2: 60 and P3: 80 kg ha-1) and four different biofertilizers (B1: Rhizobium, B2: Azotobacter, B3: Azospirillium and B4: Biozyme) comprising of twelve treatments and three replications. Maximum number of pods plant-1 (11.64 and 11.83), length of pod (13.32 and 14.08 cm), fresh pod yield plot-1 (5.99 and 6.13 kg) and fresh pod yield (62.41 and 63.90 q ha-1) were obtained with the application of (P2:60 kg phosphorous ha-1 + B1: Rhizobium).The higher gross returns (180993.83 and 185306.78 ₹ ha-1), net returns (126826.83 and 131379.78 ₹ ha-1) and B:C ratio (2.38 and 2.43) were obtained with (P2:60 kg phosphorous ha-1 + B1: Rhizobium) as compared to other treatments.
