Abstract
The experiment was conducted at the research farm of Soil Science and Agricultural Chemistry to investigate the response of nutrients, biofertilizers, and biochar on soil properties under cultivation of pea crop (Pisum sativum L.) var. Kashi Mukti. Pea (Pisum sativum L.) is an important rabi leguminous crop found in the Indian subcontinent. It is mostly grown as a winter crop in the fields of northern India and as a summer vegetable on the slopes. The experimental design used was a randomized block design (RBD) with three replications Pea was taken for study with recommended doses of fertilizers (N, P2O5 and K2O @ 20, 60 and 40 kg ha-1) was applied with Rhizobium and Biochar. The bulk density (Mg m-3) and particle density (Mg m-3) of the soil were found to be maximum in treatment T1 (NPK @ 0% + Rhizobium @ 0% + Biochar @ 0%), on the other hand, treatment T9 (NPK @ 100% + Rhizobium @ 100% + Biochar @ 100%) exhibited the highest values for pore space (%), water holding capacity (%), pH (1:2) w/v, electrical conductivity (dS m-1), organic carbon (%), available nitrogen (kg ha-1), available phosphorus (kg ha-1) and available potassium (kg ha-1). In conclusion, the experiment demonstrated that the application of NPK fertilizers, rhizobium, and biochar had a significant impact on the soil health under pea cultivation.
