The yield of a particular crop mainly depends on the biological characters viz., plant height, root nodules per plant, number of trifoliate leaves per plant, number of primary branches per plant, secondary branches per plant, dry matter accumulation (g), etc. which are generally affected by the application of different inorganic and organic fertilizers. Then, it become an important task to evaluate the effects of different combinations of these fertilizers. In the present study, we are trying to test these effects on the said growth parameters under Agri-Horticultural system on black gram (Vigna mungo L. Hepper).The treatments were comprised of two levels of inorganic fertilizers i.e., NPK (20:40:20 and 30:50:30 kg per ha) and three level of organic manure (FYM, Vermicompost and Rhizobium inoculant) in factorial randomized block design (factorial-RBD), with 12 treatment combinations, each replicated three times. The average maximum plant height of black gram was found under the combination of Vermicompost + NPK (30:50:30 kg per ha) at 20, 45 and at harvest which was 19.75, 41.52, and 51.70 cm respectively. The lowest plant height was observed at all the stages of crop growth for the control group. The increment in growth was significant. It was possibly due to the synergistic effects of soil test based NPK, Vermicompost, FYM and Rhizobium inoculant. The combination of FYM, vermicompost, inorganic fertilizers and Rhizobium inoculation had pronounced on soil fertility that resulted in better vegetative growth in plant height, number of branches per plant, number of nodules per plant, straw yield. Thus, we would recommend to use NPK with vermicompost in order to get the optimum growth and yield of black gram in Agri-horticultural system.
