In order to study the effect of uniconazole and cycocle growth regulators on growth, yield and nutrients content of pearl millet in drought stress condition, a field experiment was conducted in 2007-2008 in Agriculture Research Center of Zabol University. The experiment was conducted in split plot base on randomized completely block design with tree replications. Main plots were different levels of drought stress included: full irrigation, withholding irrigation in vegetative growth stage (beginning of rapid stem development), and withholding irrigation in flowering stage. Sub plots were of four levels micronutrients foliar application treatments (foliar application, foliar application of uniconazole, foliar application of cycocle, and foliar application of uniconazole + cycocle). In this experiment plant height, dry matter and grain yield, 1000-seeds weight, harvest index and absorption nutrients (N, P and K) content in forage were measured. The Results indicated that the highest plant height, dry matter and grain yield, 1000-seeds weight and harvest index obtained from S1 treatment. Furthermore the highest nitrogen and phosphorus content achieved from 0S1 treatment. But it hadn’t significant effect on potassium content in forage. Foliar treatments the highest plant height obtained from no foliar treatment and the lowest it achieved from foliar treatments and the most 1000-seeds weight obtained from foliar application with cycocle. In addition to the uppermost dry matter yield, grain yield and nutrients content obtained from foliar application of uniconazole + cycocle. But foliar treatments hadn't significant influence on harvest index of millet.
