Abstract:
An experiment was conducted during Kharif season (July – October) 2021 to study the “Effect of organic and inorganic sources of nutrient on soil health and Yield of Baby Corn (Zea Mays. L) Var VL 42” on crop research farm department of Soil Science & Agricultural chemistry. The experiment was laid out in Randomized block Design having three levels of NPK @ 0%, 50%, 100% ha^-1 and three levels of Vermicompost @ 0%, 50%, 100% ha^-1 respectively. The treatment combinations were replicated three times and were allocated at random in each replication. The result shows that the application of different levels combination of Organic and Inorganic fertilizer increased growth, yield of baby corn and improved soil chemical properties, however, some parameter of soil physical properties decreased. It was recorded from the application of NPK and Vermicompost fertilizer in treatment T₉- L₀+ V₀ [@ 100% NPK ha^-1 + @ 100% Vermicompost ha^-1] maximum Bulk density 1.327 Mg m^-3 in 0-15 cm and 1.329 in 15-30 cm, Particle density 2.438 Mg m^-3 in 0-15 cm and 2.439 in 15-30 cm, % pore space 51.31 in 0-15 cm and 50.34 in 15-30 cm, Water holding Capacity 59.10% in 0-15 cm and 59.40 in 15-30 cm, pH 7.69 in 0-15 cm and 7.71 in 15-30 cm, EC dSm^-10.48 in 0-15cm and 0.49 in 15-30 cm, % Organic Carbon 0.297% in 0-15 cm and 0.298% in 15-30 cm, Available N 263.99 Kg ha^-1 in 0-15 cm and 265.98 Kg ha^-1in 15-30 cm, Available P 27.67 in 0-15 cm Kg ha^-1and 26.62 in 15-30 cm, Available K 157.89 kg ha^-1 in 0-15 cm and 155.42 kg ha^-1 in 15-30 cm. It was also revealed that the application of NPK with Vermicompost was excellent source for fertilization than fertilizers. The economy of different treatment concerned, the treatment T₉ (L₂ + V₂) provides highest net profit of Rs. 39377 with cost Benefit Cost ratio (1:1.76).
