Abstract:
A field experiment was conducted during Rabi season of 2021 at Crop Research Farm (CRF), Department of Agronomy, SHUATS, Prayagraj (U.P) to investigate the effect of biofertilizers and micronutrients (Zn & B) on growth and yield of Chickpea. The treatments consist of biofertilizers (viz., Rhizobium, Phosphate Solubilizing bacteria and Rhizobium + Phosphate Solubilizing bacteria) and micronutrients (Zinc 0.5%, Boron 0.5%, and Zinc 0.5% + Boron 0.5%), whose effect is observed on chickpea (var. RVG 202). The experiment was laid out in randomized block design with ten treatments replicated thrice. The treatment with application of Rhizobium(10g/kg) + Phosphate Solubilizing bacteria(10g/kg) + Zinc(0.5%) + Boron(0.5%) recorded significantly higher plant height (50.21cm), number of branches per plant (20.20), plant dry weight (26.89 g), number of pods per plant (34.26), number of seeds per pod (2.26), seed yield (3.01 t/ha), Stover yield (5.70 t/ha) and test weight (234.96g), compared to other treatment combinations. Maximum Gross return (150544.28 INR/ha), Net return (99400.12 INR/ha) and B: C ratio (2.94) were recorded in treatment with the application of Rhizobium (10g/kg) + Phosphate solubilizing bacteria (PSB) (10g/kg) + zinc (0.5%) + Boron (0.5%) as well.
