Abstract:
A field experiment was conducted during kharif season of 2021 at experimental field of the Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology & Sciences, Prayagraj, and Uttar Pradesh, India. The soil of experimental field is Sandy loam in texture, nearly neutral in soil reaction (pH 7.4). To determine the “Effect of Organic manures and Inorganic fertilizers on the growth and yield of Black gram (Vigna mungo L.)”. The treatments consisted of Vermicompost, Neem cake, FYM and NPK viz., Vermicompost 1t/ha, Neem cake 2t/ha, FYM 4t/ha and NPK whose effect is observed on Black gram. The Experiment was laid out in Randomized Block Design with Ten treatments Replicated thrice. The results obtained that the T₄ with the application of Vermicompost 1t/ha + RDF (100%) – 20:40:20 NPK kg/ha was recorded significantly maximum plant height (44.75 cm), number of root nodules per plant (18.89), number of branches per plant (8.33), plant dry weight (11.15 g/plant), pods per plant (36.33), seeds per pod (7.00), test weight (37.14 g), grain yield (1294 kg/ha).The results obtained with the treatment of T₃ with the Appilication of Vermicompost 1 t/ha + RDF (75%)- 15:30:15 NPK kg /ha was recorded significantly maximum crop growth rate (11.07 g/m2/day) and relative growth rate (0.04 g/g/day).The results obtained with the treatment of T₄ Vericompost1t/ha + RDF (100%) – 20:40:20 NPK kg/ha recorded significantly maximum gross return (81522 INR/ha), net return (54362 INR/ha) and B:C ratio (2.00) The results obtained with the treatment of T₁₀ (Neem cake 2t/ha + RDF (100%)- 20:40:20 recorded gross return (53160 INR/ha).
