Effect of liquid biofertilizer, plant geometry and phosphorous levels on growth and yield of greengram (Vigna radiata L.)

Abstract

An experiment was conducted at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P.) during zaid season of 2017 and 2018 to studies the “Effect of liquid biofertilizer, plant geometry and phosphorous levels on growth and yield of greengram (Vigna radiata L)”. the experiment laid out in RBD (factorial) with 24 treatment and each replicated in thrice viz. four levels of liquid biofertilizer B1 untreated, B2-Rhizobium inoculation, B3- Phosphate solubilizing bacteria inoculation, B4- Rhizobium + Phosphate solubilizing bacteria inoculation Respectively. Plantgeometry,g1- row spacing 30cm ×15cm,g2 - row spacing 45cm×15cm and three levels of phosphorous, P1-40kg/ha, P2-60kg/ha, P3-80kg/ha. The pooled result of two year of experiment reveled that significantly higher values of plant height (65.94cm, 63.37cm and 63.80cm), plant dry weight (13.85g, 13.86g and 13.22g), number of nodules (13.93, 13.19 and 13.55), numbers of branches/plant (7.89,7.46 and 7.48), leaf area (142.20cm2, 125.38cm2 and 137.12cm2), number of pods/plant (31.39, 31.8 and 30.40), number of grains/pod (9.62, 8.92 and 9.24), test weight (32.16g, 30.51g and 31.39g),grain yield (13.29q/ha, 12.90q/ha and 13.61q/ha) and stover yield (23.66q/ha, 23.39q/ha and 23.30q/ha) was recorded due to biofertilizer, plat geometry and phosphorous levels respectively.
