Split plot design was used in the study on the effect of the rates of irrigation water, nitrogen and straw mulching on yield and quality of supersweet corn seeds. Main plot was used for the rates of irrigation water while subplot was occupied by the rates of nitrogen fertilizer x straw mulching. Maximum yield and quality of supersweet corn seeds are obtained by the application of 80 cm./rai/crop of water and also are obtained by the application of 30 kg.N/rai. Mulching with rice straw at the rate of 800 kg./rai gives a higher phosphorus concentration in seed comparing to the non mulching treatment. The interaction amongst the rates of irrigation is also found to effect seed yields too.
