Response of phosphorous levels, liquid biofertilizer and spacing on yield and yield attributes of green gram (Vigna radiata L.)

Abstract

An experiment was conducted at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P.) during zaid season of 2018 to studies the “Response of phosphorous levels, liquid biofertilizer and spacing on yield and yield attributes of green gram (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-Rhizobiun inoculation, B3- Phosphate solubilizing bacteria inoculation, B4- Rhizobium +Phosphate solubilizing bacteria inoculation Respectively. Plant geometry, 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 result of one year of experiment revealed that significantly higher values of plant height (66.64cm, 65.05cm and 62.97cm), plant dry weight (14.94g, 15.61g and 14.36g), number of nodules (13.86, 13.09 and 13.43), numbers of branches/plant (7.86, 7.43 and 7.59), leaf area (134.19cm2, 140.20cm2 and 128.29cm2), number of pods/plant (30.59, 32.00 and 29.30), number of grains/pod (9.70, 8.98 and 9.28), test weight (32.27g, 30.44g and 31.18g) and grain yield (13.15q/ha, 12.99q/ha and 13.60q/ha) was recorded due to biofertilizer, plat geometry and phosphorous levels respectively.
