Abstract

In order to study of DROUGHT STRESS in different growth stages on YIELD AND YIELD COMPONENTS of CORN hybrid S.C.704 in different PLANT DENSITY, this research was conducted in Ahvaz, during the summer 2008, in split-plot using RCBD with three replications. Water holding were applied in main plot in four levels (water holding at eight leaves stage, twelve leaves stage, tasseling growth stages and optimum irrigation was as the control). PLANT DENSITY were as three sub plots in three levels (7.5, 8.5, 9.5 plant per square meter). Results showed that grain yield, biological yield and harvest index affected by water holding and plant population. Grain yield and harvest index was more affected in water holding in tasseling stage compare with other treatments. Maximum grain yield (890 gr/m2 ) was belonged to control water treatment with 75000 plant productions while minimum grain yield was obtained in tasseling stage with production 95000 plants with change in density of 75000 to 95000. Grain yield and harvest index decreased in response to plant population from 75000 to 95000 plants per hectare, while biological yield increased to PLANT DENSITY increment. In interaction treatment S4D2 yielded the highest grain yield (934 gr/m2 ) while the lowest grain yield was belonged to S3D3 with 152 gr/m2.
