Abstract
This study was conducted to determine the yield and biomass of sweet corn (Zea mays) applied with balanced fertilization and organic fertilizer. The field trials was laid out in RCBD factorial design with 5 treatments and 3 replications. The findings revealed that balanced fertilization plus 75% to 125% of vermicast significantly higher on yield but insignificantly different with biomass. The return of investment showed insignificant difference on both treatments. However, the highest percentage of the highest return of investment is the balanced fertilization strategy plus compost based on the recommended rate of Bureau of Soils and Water Management. Balanced fertilization plus rate of vermicast of 100-125% gave the best and significant performance in sweet corn yield. Through chemical analyses, Vermicast fertilizer have a composition of 2%Nitrogen, 12%P2O5, 2%K2O, 6%Calcium, 9%Magnesium, 0.45%Zinc, 2.5%Sulfur, 0.2%Manganese, 5%Iron, 0.2%Copper, 0.1% Boron, 1%Molybdenum, 1% Chloride, and about 29% organic matter that promotes best growth in Zea mays. Thus, it is concluded that balanced fertilization plus vermicast with a rate of 100-125% is the best fertilization strategy to increase the yield of sweet corn of about 25% as compared to balanced fertilization alone.
