Growth and yield of blackgram as influenced by water soluble fertilizers and plant growth promoting rhizomicrobial consortia under rainfed condition in southern transition zone of Karnataka

Abstract

A field experiment was carried out during Kharif-2019 at College of Agriculture, University of Agricultural and Horticultural Sciences, Shivamogga, to study the influence of water soluble fertilizers and liquid plant growth promoting rhizomicrobial consortia on black gram (Vigna mungo L.) under rainfed condition in Southern Transition Zone of Karnataka. Experimental design adopted was RCBD with three replications and thirteen treatments consisting of different combinations of water soluble fertilizers viz.,19:19:19 (N: P: K) and Mono potassium phosphate (0:52:34) sprayed at 30 and 45 days after sowing with or without liquid plant growth promoting rhizomicrobial consortia application along with the package of practice. The Results revealed that, foliar application of 19:19:19 (N: P: K) and Mono potassium phosphate (0:52:34) @ 1 per cent each at 30 and 45 days after sowing + PGPR along with a package of practice recorded significantly higher plant height (67.16 cm), number of branches plant-1 (10.63), number of leaves plant-1 (16.95), leaf area (5.57 dm2 plant-1), total dry matter production (15.84 g plant-1), number of pods plant-1 (25.20), pod length (7.92 cm), number of seeds pod-1 (6.53), seed yield (1167.62 kg ha-1) and haulm yield (2019.37 kg ha-1) over package of practice.
