Abstract:
An experiment was conducted during in Zaid season (March 2021-June 2021) in an Inceptisols of Prayagraj, (U.P.) India” to study the entitled “Effect of Organic and Inorganic Source of Nutrients on Physio-Chemical Properties of Soil in Black Gram (VignaMungo L.) The experiment was laid out in randomized block design with three levels of NPK (0% NPK, 50% NPK and 100% NPK) and three levels of FYM (0% FYM, 50% FYM, 100% FYM). The result shows that application of different levels combination of inorganic fertilizers increased growth, yield of black gram and improved soil chemical properties. It was recorded from the application of NPK and FYM fertilizers in treatment T₉ (NPK @ 100% + FYM @ 100%) maximum bulk density 1.228 Mg m^-3 at 0-15 cm and 1.232 Mg m^-3 at 15-30 cm, particle density 2.485 Mg m^-3 at 0-15 cm and 2.489 Mg m^-3 at 15-30 cm, pore space 52.26% at 0-15 cm and 49.81% at 15-30 cm, water holding capacity 43.62% at 0-15 cm and 38.52% at 15-30 cm, pH 7.32 at 0-15 cm and 7.02 at 15-30 cm, electrical conductivity 0.49 dSm^-1 at 0-15 cm and 0.60 dSm^-1 at 15-30 cm, organic carbon 0.58% at 0-15 cm and 0.56% at 15-30 cm, available nitrogen 329.23 kg ha^-1 at 0-15 cm and 326.70 kg ha^-1 at 15-30 cm, available phosphorus 34.86 kg ha^-1 at 0-15 cm and 32.76 kg ha^-1 at 15-30 cm, available potassium 214.54 kg ha^-1 at 0-15 cm and 207.63 kg ha^-1 at 15-30 cm. Plant parameters also increase dose of NPK and FYM with cost benefit ratio is 1: 3.54 best from T₁ [(control) NPK @ 0% + FYM @ 0%] respectively.
