Effect of Integrated Nutrient Management on Soil Fertility and Productivity in Maize

Abstract

A field study was carried out at Vanavarayar Institute of Agriculture, Manakkadavu, during November 2012-January 2013 to study the effect of INM on soil fertility and productivity on maize (Zea mays). Six different treatments with three replications each were carried out in the plot in RBD design.INM practice including vermicompost and recommended dose of NPK showed its best results with respect to leaf area and plant height as compared to other treatments.INM practice including vermicompost and recommended dose of NPK showed its best results with respect to yield parameters like number of grains per cob, 100 seed weight and yield(4112 kg ha-1).Weight of the cob was recorded maximum in INM
