Effect of different levels of fertilizers and organic matter on soil Physico chemical properties, growth and yield of baby corn (Zea mays L. G 5414 Variety
Organic and inorganic nutrients are important for crop productivity and soil health. Present study investigated the Effect of different levels of fertilizers and organic matter on soil physico chemical properties, Growth and yield of Baby Corn (zea mays L) G 5414 Variety. Field experiment was conducted at Department of Soil Science and Agricultural Chemistry, Naini Agricultural Institute, Prayagraj 211007, during kharif 2019 on loamy sand soil. The experiment consisted of 9 treatment viz. T0 Control (No Treatment) T1 NPK 100% Organics 0% T2 NPK0% vermicompost 100% 10 t ha 1, T3 NPK 0% Poultry manure 100% 10 t ha 1,T4 NPK 75% Vermicompost 25% 82:39:20kg ha1+2.5 t ha 1, T5 NPK 75% Poultry manure 25% 82:39:20 kg ha 1 +2.5:1tha 1, T6 NPK 50% Vermicompost 50% 55:26:13 kg ha 1+5t ha 1 and T7 NPK50% Poultry manure 50%55:36:13 kg ha 1 5t ha1T8 NPK 50% Organics 25% 55:26:13 kg ha 1+2.5:1t ha 1. Conclusively, integration of inorganic fertilizers with organic manures can be used with optimum rates to improve crop productivity on sustainable basis. The results showed that progressive increase in level of N P K and organic fertilizer used from different sources in the experiment, the treatment combination(NPK 50% Organics 25% significantly increased the physical and chemical analysis parameters i.e. (Bulk density (Mg m 3) Particle density (Mg m 3) Pore space of solid space, Specific gravity, Water retaining capacity Soil pH (1:2) EC (dSm 1) Organic carbon Available Nitrogen (Kg ha 1) Available Phosphorus (Kg ha 1) and Available Potassium (Kg ha 1)of soil.
