In late rainy season, the 40 day treatment yielded the other treatments except the 50 day treatment, giving 5,955 fresh ears per rai which was amount to 920 kilograms per rai of unhusked ears. The 50 day treatment gave 5 600 fresh ears per rai which is equivalent to 804 kilograms per rai of unhusked ears. The control treatment gave the lowest yield of 4,789 fresh ears per rai or 538 kilograms per rai of unhusked ears.
