Influence of bio fertilizers and chemical fertilizers on the exo-morphological characters of vigna mungo (linn.) hepper

The influence of bio fertilizers and chemical fertilizers (NPKS) on the exo morphological characters of black gram (Vigna mungo). The soil quality was monitored during the experiment followed by growth and productivity. In a vermicompost 50% there has been a significant improvement in soil qualities in plots treated with vermiwash 10% and chemical fertilizer (NPKS). The growth and yield of black gram was significantly higher in pots treated with vermicompost 50%. The bio fertilizer can be economically and environmentally suitable for the soil environment.
