According to farmer interviews, most of farmers were literate, source of knowledge in corn production was extension workers, hiring additional farm labors was high because of lack of family labor, using fertilizer was high, in otherwise hybrid variety use was low. From experimental results of level experiment by comparing 12 varieties, ten fertilizer formulas, seven methods of fertilizer application, and six methods of weed control; indicated that yields of hybrid varieties were higher than suwan 1 Variety, fertilizer formulas affected corn yields significantly, but no significant differences in methods of fertilizer application and weed control.
