To investigated efficacy of skip irrigation and some of plant growth regulator and sunflower extract on maize yield, a field experiment was conducted on field crop department - college of agriculture / was it university at summer season 2013. RCBD design by split plot arrangement was used to study skip irrigation treatment as main plots, with four treatment of growth regulators as subplots represent GA3 (100 ppm), salicylic acid (200ppm), sunflower extract (5% w/v) and control treatment (distil water only). Two spread were repeated on shot plant; first was after month from sowing and second before flowering stage. Result showed decline of maize yield by skip irrigation treatment compared with traditional irrigation by 23% percentage. While improved growth components yield of maize. Sunflower extract, GA3 and salicylic acid were increased yield by 19, 15 and 13% percentage alternatively compared with control. Interaction between irrigation treatment and growth regulator was not significant. However growth regulator component caused equal increased with both irrigation ways, as well as, sunflower extract applied or GA3 amended from crop ability of drought tolerance in skip irrigation treatment, which not significant different in yield from traditional treatment irrigation and that refer to moderated of effect drought on yield. Yield component appeared that yield was come to increased number of grain and weight of grain bases which represent essential yield component. From this result, can be concluded that ability of saving 50% percentage from water irrigation and keeping of maize yield through using of skip irrigation with moderated water stress by growth regulator or sunflower extract sprayed on maize.
