Abstract

The yield and agronomic efficiency of super sweet corn variety were evaluated under six fertilizer combinations (100% inorganic fertilizer, 100% organic fertilizer, 75% inorganic fertilizer + 25% organic fertilizer, 50% inorganic fertilizer + 50% organic fertilizer, 25% inorganic fertilizer + 75% organic fertilizer, control or no fertilizer) during 2011 dry season at University of the Philippines, Los Baños College, Laguna. At flowering and harvest stages, significant differences in grain yield and other yield parameters were observed in some of the agronomic parameters due to varying fertilizer treatments. The application of 75% inorganic + 25% organic fertilizer produced the best response in terms of agronomic parameters while the 50% inorganic + 50% organic fertilizer treatment gave the highest grain yield. It was observed that ear diameter and 100-kernel weight were affected by the foliar fertilizer application, although it did not increased grain yield. Application of organic fertilizer appeared to minimally improved the soil properties relative to the inorganic fertilizer application. Although the effect of the 50% inorganic + 50% organic fertilizer treatment was not reflected in most agronomic parameters, it produced the highest grain yield where could be attributed to high harvest index. Further long-term studies are needed on fertilizer contributions and xii the application of foliar fertilizer particularly under conditions wherein water and other factors are not limiting.
