A field experiment was conducted in Padang Besar, Perlis, Malaysia from 15/2/2014 and 15/2/2015 two seasons. In each year, the experiments have been implemented in order to study the effect of three levels of irrigation water (25% (no stress), 50% (moderate deficit), 75% (water deficit) of field capacity), and five concentrations of GA3(0, 50, 100, 200, 300 ppm) and five concentrations of proline (0, 100, 200, 300, 400 ppm) on the yield and productivity of maize.The results showed a significant influence of sprayed GA3on the maize leaves, where excellence sprayed 300ppm GA3 with a high rate of all the study characteristics with sprayed 300ppm of gibberellic acid except cobs per plant. The results of the interaction between GA3and water deficit showed the clear influence of water deficit in reducing all characteristics of study where excelled the interactions (300ppm GA3 and 25% from field capacity) with a high rate of majority study characteristics, but these increases were not sufficient. Concluded from the results of the study great positive impact of sprayed proline on the all of the growth characteristics, it characterizes the concentration of 400ppm with the highest rate of majority study characteristics. The study results showed into increased the rate of protein, chlorophyll content, and oil, with sprayed 400ppm of proline.
