Application of eight irrigations (seedling, 6 leaf, knee-high, before tasseling, 50% tasseling, 50% silking, grain formation and grain filling stages) where no stress was occurred significantly increased dry matter distribution. Data related to dry matter partitioning in stem, leaves and cobs at 25, 50, 75 and at harvest stage of crop. In general, irrespective of the treatments, crop attained maximum leaf dry weight at flowering stage. This decreased progressively up to harvest stage. While, stem dry weight showed increasing trend up to tasseling and silking stage and than declined slightly towards harvest stage of the crop. Obviously, cobs dry weight increased linearly from flowering up to harvest stage.
