Effect of water-soluble fertilizers and plant growth promoting rhizomicrobial consortia on nutrient content, uptake and soil chemical properties in blackgram

The field experiment was conducted with an objective to study the effect of water-soluble fertilizers and PGPR on yield and nutrient uptake of blackgram under rainfed condition during 2019 at University of Agricultural and Horticultural Sciences, Shivamogga. Kharif - Initial soil nutrient status showed that available nitrogen (242.22 kg ha^-1), high phosphorus (75.08 kg P₂O₅ ha^-1) and medium potassium (135.63 kg K₂O ha^-1) was low. There were thirteen treatments consisting of different combinations of 19:19:19 and monopotassium phosphate (0:52:34) with or without liquid plant growth promoting rhizomicrobial consortia application. Treatments significantly influenced by foliar fertilization and plant growth promoting rhizomicrobial consortia application. The foliar application of 19:19:19 (N: P: K) and monopotassium phosphate (0:52:34) @ 1 per cent each at 30 and 45 days after sowing + PGPR along with a package of practice treatment recorded significantly higher nitrogen, phosphorous, potassium content (3.52, 0.42 and 2.10 %, respectively in seed) and uptake (69.49, 9.26 and 64.08 kg ha^-1, respectively) and also observed higher soil available N, P and K at 60 DAS and at harvest stage, respectively in the same treatment over package of practice.
