An experiment was conducted on “Effect of different level of N P K and Biochar on Soil Physico-chemical properties and Yield Attribute of Black gram (Vignamungo L.) Var. KPU 07-08” during Rabi season 2019-20 at the Research farm Department of Soil Science and Agricultural Chemistry, Naini Agriculture Institute, SHUATS, Prayagraj. The design applied was 3x3 randomized block design having three factors with three levels of NPK @ 0, 50, and 100 % ha-1, three levels of Biochar @ 0, 50 and 100% ha-1 respectively. The result obtained with treatment T8- [N P K @ 100 % + Biochar @ 100%] that showed the highest yield regarding, gave the best results with respect to plant height 60.10 cm, number of leaves plant-1 34.00, No. of pod plant-1 38.77, it gave highest yield 13.05 q ha-1Biochar in combination resulted in a slight increase in soil pH 7.25, Electrical conductivity 0.28 dSm-1. In post-harvest soil of NPK fertilizers observations were resulted in significant increase in Organic carbon 0.79 %, Particle density 2.64Mg m-3, Bulk density 1.10 Mg m-3,Pore space 58.33 % and available N 340.23 kgha-1, P 35.85 kg ha-1, K 206.64 kg ha-1, significant increase in case of Nitrogen (kg ha-1), Phosphorus (kg ha-1), Potassium (kg ha-1) was found to be significant among other treatments in Black gram cultivation and soil quality improvement. It was also revealed that the application of N P K with Biochar was excellent source for fertilization than fertilizers.
