Abstract:
An experiment was conducted during in kharif season (June 2021- Aug 2021) to study the “Effect of Different Levels of NPK And Zinc on Soil Health, Growth and Yield of Baby Corn (Zea mays L) G-5414 Variety” Research farm Dept. of Soil Science and Agriculture Chemistry The experiment was laid out in randomized block design with three levels of NPK (0% NPK, 50% NPK, 100% NPK) and three levels of Zinc (0% Zn, 50% Zn, 100% Zn,) The treatment combinations were replicated three times and were allocated at random in each replication The result show that application of different levels combination of inorganic fertilizer increased growth, yield of maize and improved soil chemical properties, However, some parameter of soil physical properties decreased. It was recoded from the application of NPK and Zinc fertilizer in treatment T9 (100% NPK [ N (150 kg ha-1), P (60 kg ha-1), K (40 kg ha-1)] + 100% Zinc [25kg ha-1]) maximum plant height (165.33 cm), number of leaves (11.43), cob length was (8.86 cm), Bulk density (1.28Mg m -3), Particle density (2.91Mg m-3), % pore space with 47.66%, Organic carbon (%) (0.77%), Electrical conductivity (0.26 ds m -1), Available Nitrogen (315 kg ha-1), available Phosphorous (29.3 kg ha-1), Available Potassium (198.3kg ha-1), Available Zinc (0.91kg ha-1), maximum Benefit Cost ratio(2.43), best from T1(control).
