Effect of Different Bio-Fertilizers Applied as Supplemental Foliar Spray on the Growth and Yield ff Corn

Different bio-fertilizers like Fermented Plant Juice (FPJ), Indigenous Micro-Organisms (IMO) and Effective Microorganisms Activated Solution (EMAS) was prepared and applied as foliar spray to evaluate its effects on the growth and yield of corn at Conner, Apayao condition. Initial application was at 25 days after planting (DAP) and re-application after 7 days for 5 consecutive weeks. The different bio-fertilizers differed significantly in final plant height, ear height, number of leaves, ear length, ear diameter, weight of 1,000 seeds, yield per quadrant and computed yield. On the other hand, there was no significant difference on the number of rows per ear, shelling recovery and drying recovery. EMAS produced the tallest plant, highest ear height, the most number of leaves, longest ear length, biggest ear diameter, heaviest weight of 1,000 seeds, and highest weight per quadrant and computed yield. Furthermore, EMAS and IMO registered the highest ROCE while control was almost similar with the vermi tea and FPJ had the lowest.
