Yield Performance of Hybrid Glutinous Corn As Influenced By Third Generation Nutrition Bio-Fertilizer

Abstract

The study was conducted to determine the performance of two corn varieties and Third Generation Nutrition Bio-fertilizer interaction and to determine the return of investment of the different treatment combinations. The study was conducted at the experimental area of the Institute of Agricultural Technology, Isabela State University, Cauayan City Isabela. There were two factors used as treatments in the study. Main-plot (variety) using to corn varieties and sub-plot (fertilizer) F₁-Farmers practice (100 kg 14-14-14, 100 kg 16-20-0, & 100 kg urea ha^-1, F₂- 50 kg 14-14-14, 50 kg 16-20-0, & 50 kg urea ha^-1, +75 kg Aishawariya , 1000 ml New Suryamin, 500 ml Wonder , and 500 ml Megacal ha^-1, F₃- 70 kg 14-14-14, 70 kg 16-20-0, & 70 kg urea ha^-1, +37.5 kg Aishawariya , 500 ml New Suryamin, 250 ml Wonder , and 250 ml Megacal ha^-1, and F₄- 150 kg Aishawariya , 2000 ml New Suryamin, 1000 ml Wonder , and 1000 ml Megacal ha^-1). The experiment was laid out following the split plot design. The two corn varieties had insignificant differences on plant height. The ear height, ear weights with and without husk, ear length, ear diameter and corn ear yield per sampling area obtained from the two varieties were comparable with each other. The plants applied with 70 kg 14-14-14, 70 kg 16-20-0, & 70 kg Urea ha^-1, +37.5 kg Aishawariya, 500 ml New Suryamin, 250 ml Wonde , and 250 ml Megacal ha^-1 produced the tallest plants , ear weights with and without husk, ear length and ear diameter.  The different treatment combinations produed comparable heights at 30 days after planting but significant differences among the treatment combination were observed at 60 days after planting. The combined effect of 70 kg 14-14-14, 70 kg 16-20-0, & 70 kg Urea ha^-1, +37.5 kg Aishawariya, 500 ml New Suryamin, 250 ml Wonde , and 250 ml Megacal ha^-1 is recommended for glutinous corn because it obtained the highest yield and return on investment.
