Effect of Chemical Fertilizers, Rhizobium and Phosphate Solubilizing Bacteria on Growth, Yield and Quality of French Bean (Phaseolus vulgaris L.)

Abstract

The investigation was carried out during 2019-20 at HRS, Mondouri, BCKV, Nadia, West Bengal to find out the effect of biofertilizers with different levels of inorganic fertilizers. The experiment was laid out in RBD with three replications. Two biofertilizers (Rhizobium phaseoli and PSB) and four levels (100%, 75%, 50% and 25%) of RDF were included in this experiment along with recommended dose of NPK (100:60:50 kg ha⁻¹). Among different treatments, highest plant height (35.10 cm), number of primary branches plant⁻¹ (4.20), number of pods plant⁻¹ (8.00), length of pod (15.44 cm), total pod yield (12.51 t ha⁻¹), and crude protein content (3.19 %) was recorded when seeds were treated with Rhizobium phaseoli biofertilizer @10 g Kg⁻¹ seeds and soil application of PSB @2.5 Kg ha⁻¹ along with application of 75% RDF.
