Abstract:
An experiment was conducted during Rabi season (Nov. 2021 – Feb. 2022) to study the “Effect of Organic and Inorganic Sources of Nutrients on Physico-Chemical Properties of Soil in Garden Pea (Pisum sativum L.) Var. GK-10”. On central research farm of Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj. The experiment was laid out in randomized block design with three levels of NPK (0% NPK, 50% NPK and 100% NPK), and three level of FYM (0% FYM, 50% FYM and 100% FYM). The excavated soil sample from experimental site before conducting research operation, mentioned that, soil is of sandy loam texture with neutral to alkaline in reaction and significantly highest in treatment. The treatment combinations were replicated three times and were allocated at random in each replication. The result shows that application of different levels combination of inorganic fertilizers increased growth, yield of garden pea 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 1.265 Mg m^-3 at 0-15 cm and 1.267 Mg m^-3 at 15-30 cm, particle density 2.522 Mg m^-3 at 0-15 cm and 1.527 Mg m^-3 at 15-30 cm,% pore space 54.78% at 0-15 cm and 52.68% at 15-30 cm, water holding capacity 44.75% at 0-15 cm and 43.82% at 15-30 cm, pH 6.85 at 0-15 cm and 7.08 at 15-30 cm, EC 0.469 dSm-1 at 0-15 cm and 0.476 dSm-1 at 15-30 cm, organic carbon 0.564% at 0-15 cm and 0.568% at 15-30 cm, available nitrogen 311.56 kg ha^-1 at 0-15 cm and 304.55 kg ha^-1 at 15-30 cm, available phosphorus 37.70 kg ha^-1 at 0-15 cm and 34.28 kg ha^-1 at 15-30 cm, available potassium 221.42 kg ha^-1 at 0-15 cm and 211.67 kg ha^-1 at 15-30 cm with cost benefit ratio is 1: 2.27 best from T₁ [(control) NPK @ 0% + FYM @ 0%].
