Influence of Farmyard Manure and Bio-Fertilizers on Growth and Yield of Green Gram

Abstract

A study was conducted with the objective to evaluate the influence of Farmyard Manure and  bio-fertilizers on growth and yield of green gram. The field experiment was conducted during Zaid season 2023 at Crop Research Farm, Department of Agronomy, Sam Higginbottom University of Agriculture, Technology And Sciences, Prayagraj, Uttar Pradesh, India. The soil of the experimental field was sandy loam in texture, slightly alkaline in soil reaction (pH 8), low level of organic carbon (0.28%), available N (219 kg/ha), P (11.6 kg/ha) and K (217.2 kg/ha). The experiment was conducted in Randomized Block Design consisting of 9 treatments with 3 different levels of FYM 05t/ha, 10t/ha, 15t/ha and different biofertilizers Rhizobium 20g/kg seeds, PSB 20g/kg seedsand Trichoderma 4g/kg seeds with three replications and the treatments were allocated randomly in each replication. The results showed that treatment 7 with the application of FYM 15 tonnes/ha + Rhizobium 20g/kg seeds recorded significantly higher plant height (51.32cm), higher plant nodules (30.20), higher plant dry weight (13.69g), maximum crop growth rate (12.53g/m2 /day), maximum number of pods/plant (19.47), higher seed yield (1513 kg/ha) compared to other treatments. The maximum gross returns (117257.00NR/ha) and maximum net returns (78577.50 INR/ha), whereas highest benefit ratio (2.86) was recorded in treatment 1 with the application of FYM 15 tonnes/ha + Rhizobium 20g/kg seedsas compared to other treatments.
