Optimizing Nutrient Management of Hybrid Glutinous Corn Using Double Row Planting Technology

This study was designed to determine the optimal nutrient management strategy for hybrid glutinous corn cultivated using the double-row planting method. Six treatments mixing organic and inorganic fertilizers with various foliar inputs were studied at Villa Cruz, San Mateo, Isabela, from August 15 to October 25, 2023. The treatments were laid out in a Randomized Complete Block Design with three replications. Among the treatments, the combination of half the recommended rate (½ RR) of inorganic fertilizer, 3 tons per hectare of vermicast, and Power Grow Foliar (T4) showed the most potential. T4 yielded the heaviest corn ears, the highest green corn production at 10.3 tonnes per hectare, and the largest ear diameter, both with and without husk. With a return on investment of 330.96%, it had the highest performance. The findings indicate that incorporating double-row planting with a balanced application of organic and inorganic inputs can substantially enhance the profitability and productivity of hybrid corn production. The study promotes future research to verify the success of this nutrient management approach in several environments and recommends acceptance of it.
