Performance of Blackgram as Influenced by Water Soluble Fertilizers and PGPR under Rainfed Situation

Lower production potential of blackgram grown under rainfed situation due to lack of proper nutrition during critical crop growth stages. So, investigation was carried out with an objective to study the effect of water-soluble fertilizers and PGPR on performance of blackgram during Kharif-2019, a field study was carried out at University of Agricultural and Horticultural Sciences, Shivamogga which comes under Southern Transition Zone of Karnataka. Experimental design was laid out in randomized complete block design with thirteen treatments and replicated thrice. Treatments include combination of 19:19:19, monopotassium phosphate @ different dosage foliar spray with and without PGPR treatment along with package of practices. Water soluble fertilizers viz., 19:19:19 (N: P: K) and mono potassium phosphate (0:52:34) were used in treatment combinations along with PGPR. The Results revealed that, foliar application of 19:19:19 and mono potassium phosphate @ 1 per cent each at 30 and 45 days after sowing + PGPR along with a package of practice recorded significantly higher plant height, number of branches per plant, leaf and stem dry weight, crude protein (26.54 %), seed yield (1167 kg ha-1) and haulm yield (2019 kg ha-1) over package of practice treatment and also positive correlation was found between growth and yield parameters with seed yield and haulm yield.
