IMPROVING THE YIELD OF HYBRID CORN USING BIOPRIME NANOFERTILIZER UNDER ECHAGUE, ISABELA CONDITION

Abstract

The study was confined to Dalibubon, Jones, Isabela from June 5 to September 20, 2022, to evaluate the effect of Bioprime nanotechnology on increasing the productivity of hybrid corn in Isabela. The different treatments used were varying levels of inorganic fertilizer and Bioprime NPK nanofertilizer (T1 – 140-20-30 kg NPK ha¬-1, T2 – 70-10-15 kg NPK ha¬-1 + 5g Bioprime seed treatment, 10g soil treatment and 5g foliar spray at 25 DAP, T3 – 70-10-15 kg NPK ha¬-1 + 5g Bioprime seed treatment, 10g soil treatment and 5g foliar spray at 25 and 35 DAP, T4 – 105-15-22.5 kg NPK ha¬-1 + 5g Bioprime seed treatment & 10g soil treatment and 5g foliar spray at 25 and 35 DAP, T5 – 140-20-30 kg NPK ha¬-1 + 5g Bioprime seed treatment, 10g soil treatment and 5g foliar spray at 25 DAP, T6 – 70-10-15 kg NPK ha¬-1 + 10g Bioprime soil treatment and 5g foliar spray at 25 DAP) laid-out in a randomized complete block design (RCBD), with three replications.

Findings suggest insignificant results in terms of height and stem of plants at 30, 60, and 90 DAP, number of roots at 30 DAP and harvest, ear length, ear diameter, ear weight per plant and 15m2 sampling area, grain weight and moisture, weight of 100 kernels, weight and length of roots. Highest shelling recovery was found in T5 with 77.51%. Overall, reduced utilization of inorganic fertilizer along with a system of application of Bioprime nanofertilizer for growing hybrid yellow corn exhibits promising potential in terms of increasing yield as well as economic returns. More specifically, a reduction of inorganic fertilizer at 25% supplemented with 25 g Bioprime nanofertilizer and a reduction of inorganic fertilizer at 50% applied with 15 g Bioprime nanofertilizer are recommended in hybrid yellow corn production.
