Evaluation of Green Gram (Vigna radiata L. var PDM 139) Cultivated and Harvested Soils Supplemented with Nano Urea, Rhizobium and Farm Yard Manure

A study was conducted to investigate the “Evaluation of varying levels of Nano urea, FYM, and rhizobium on soil properties and yield characteristics of green gram (Vigna radiata. L) var. PDM 139” at the research farm of soil science and agricultural chemistry. The experiment followed a randomized block design (RBD) with three replications. Treatment T9 (NU at 100% + RZ at 100% + FYM at 100%) showed a slight decrease in pH (6.96 PH), bulk density (1.27 mg m-3), particle density (2.46 mg m-3), there was a significant increase in pore space (48.90%), water holding capacity (46.51%), EC (0.20 ds m-3), organic carbon (0.58%), available nitrogen (320 kg ha-1), phosphorus (21.4 kg ha-1), potassium (195.12 kg ha-1), and plant growth. Among all the treatment joint use of T9 (NU at 100% + RZ at 100% + FYM at 100%) showed the most significant impact on green gram growth through healthy soil.
