Effect of Different Levels of Fertilizer Application along with Organic Manure on Maize Yield and Soil Fertility

A field experiment was conducted at at Regional Agricultural Research Station, Maruteru, West Godavari district, Andhra Pradesh during Rabi,2014-15 and 2015-16 to find out integrated nutrient management effect on maize with ten treatments i.e. T1 (Control), T2 (100% RDF), T3 (100% RDF + 25% RDF through FYM and vermicompost), T4 Soil Test Based Fertilizer Recommendation, T5 (125% RDF), T6 (150 % RDF), T7 Farmers Practice in RBD with 3 replications. Maize variety Kaveri Corn-50 was taken for study. The results revealed that the grain yield of maize respond significantly with the different treatment combination. The result showed highest grain yield (85.52 q ha-1) with the application of 150% RDF, which was on par with the125% and 100% Recommended Dose of Fertilizers along with organics. The organic carbon content of the soil and available nutrient status of soil was found to be high in integrated nutrient management treatments and nutrient uptake in grain and stalk was also found to be high with the treatment receiving 150% recommended dose of fertilizers.
