Effect of Photosynthetic Bacteria, Vermiwash and Phosphorus Solubilizing Bacteria on Growth, Yield and Quality of French Bean (Phaseolus vulgaris L.)

Abstract

The present investigation was carried out with title ‘Effect of Photosynthetic bacteria, Vermiwash and Phosphorus Solubilizing Bacteria on growth, Yield and Quality of French bean (Phaseolus vulgaris L.)’ at the Central Research Farm, Department of Horticulture, Naini Agricultural Institute, Sam Higginbottom University of Agriculture Technology and Sciences, Prayagraj, Uttar Pradesh during the 2021-22 with a view to identify the effects of different combinations of biofertilizers and organic nutrition and its role in growth, yield and quality of French bean variety Lakshmi. The experiment was laid in Randomized block design with 7 treatments and 3 replications with different combination in Biofertilizers and application of organic nutrition. Under this experiment, overall, 7 treatment was taken T1 (Photosynthetic Bacteria @ 30 ml/ m2 (PSB-1)), T2 (Vermiwash @ 40 ml/ m2 (VW)), T3 (Phosphate Solubilizing Bacteria (30 ml/ m2) (PSB-2)), T4 (PSB-1 + VW (40 each ml/ m2)), T5 (PSB-1 + PSB-2 (30 ml/ m2)), T6 (PSB-2 + VW (40 ml/ m2)) and T0 (Control). From the above experimental finding it was concluded that the treatment T5 (PSB-1 + PSB-2 (30 ml/ m2) was found to be best in the terms of growth parameters like plant (240.51 cm), plant spread (1984.64 cm2), earliness parameters like days to first flowering (54.33 days), days to 50% flowering (64.67 days), days to first pod setting (59.78 days) and days to first pod picking (67.47 days). T5 (PSB-1 + PSB-2 (30 ml/ m2) was also found best in terms of yield parameters like number of pods per plant (132.33 pods), pod length (13.73 cm), pod width (10.11 mm), individual pod weight (7.99 g), yield per plant (1.04 kg/plant) and yield per hectare (12.53 t/ha) of French bean. Therefore, Treatment combination of biofertilizers T5 (PSB-1 + PSB-2 (30 ml/ m2) can be suggested for better yield achievement in French bean.
