The fertilization rate of 150-120-140 is found best for Fina, 120-130-140 for Isola, 120-140-160 for Conchita and 120-140-140 for Cosima. With the application of 834 big kerosene cans of chicken dung/ha however, Conchita and Cosima could be fertilized with decreased rates of 120-130-140 and 120-130-0, respectively. The use of chicken dung also increases the yield from 21.0 to 21.84 from 23.03 to 26.17 tons/hectare (t/ha) for Conchita and Cosima, respectively. This increases the profit despite the increases in input cost
