Abstract
Significantly higher yield of rice was obtained from the standard tillage plots during the wet season planting. No marked differences on the yield, however, was observed among the different tillage methods in the dry season. The time of nitrogen application did not affect significantly the yield of C4-63 in both seasons. In general, the tillage methods had little effect on the yield components studied. The application of 80 kg N/ha during the wet season and 120 kg N/ha in the dry season applied at planting time resulted in significantly more tillers per hill until panicle initiation.
The total cost of tillage and transplanting of the rotovated plots, pre-plant sprayed with 0.4 kg/ha paraquat plus 0.75 kg/ha MCPA was the lowest among the tillage treatments for both seasons. The unplowed plots. Sprayed pre-planting with 0.6 kg/ha plus 0.75 kg/ha MCPA gave the highest total cost.
