Impact of Integrated Nutrient Management on Physico-chemical properties of soil in Pea (Pisum sativum L.) var. GS 10

Abstract

During the rabi season of 2021-2022, a field experiment was conducted at the soil science research farm of the Sam Higginbottom University of Agriculture, Technology and Sciences in Prayagraj, UttarPradesh, India. Three different parameters viz., three levels of NPK, FYM at 0%, 50%, and 100% ha-1, and three levels of rhizobium inoculation at 0%, 25%, and 50% ha-1 were used in the study. The result obtained with treatment T9[I3@100% + F3@ 100% + R3@50%] had a bulk density (1.17 Mg m-3) at 0-15cm and (1.18 Mg m-3) at 15-30 cm, particle density (2.41 Mg m-3) at 0-15cm and (2.42 Mg m-3) at 15-30, pore space (58.26%) at 0-15cm and (58.09%) at 15-30cm, water holding capacity (58.60%) at 0-15cm and (58.13%) at 15-30, pH (7.75) at 0-15cm and (7.75) at 15-30cm, EC (0.47dSm-1) at 0-15cm and (0.48 dSm-1) at 15- 30cm, soil organic Carbon (0.58%) at 0-15cm and (0.49%) at 15-30cm as regards soil available nutrients, available nitrogen (280.86 kg ha-1) at 0-15cm and (286.40) at 15-30cm, available phosphorus (16.56 kg ha-1) at 0-15cm and (17.26 kg ha-1), available potassium (178.13 kg ha- 1) at 0-15cm and (172.80 kg ha-1). The use of FYM and Rhizobium, as well as its blend with complete NPK, significantly improves the growth and overall production of Pea.
