Soil health Index demands organic fertilizer usage may be imperative couple with chemical fertilizers. Mungbean (Vigna radiata) yield and nutrients content were studied during kharif 2019 through coal and plant based humic acid (HA) application at NARC. The plots were arranged in randomized complete block design (RCBD). Results indicated that application of HA couple with chemical fertilizers significantly improved mungbean yield and nutrients content. HA at 15 kg ha-1 along with 50 kg ha-1 DAP recorded the highest grain yield (0.79 t ha-1) that is 14.4% more than the control (0.69 t ha-1) receiving 100% DAP application alone. The highest concentration of P (0.34 %), K (3.7%) and N (3.65%) in whole shoot mungbean were observed in the treatment where HA was applied at 15kg ha-1 along with 50 kg ha-1DAP. Residual organic matter improved by 0.06%. Based on findings of this study it can be suggested that HA couple with inorganic fertilizer application have significant effect on grain yield and nutrients content of N and P. It showed that HA mayenhanced NO3 and P availability through chelation and reduce soil P fixation.
