Abstract

To investigate NITROGEN STRESS and PLANT DENSITY on agronomic traits of RICE (Tarom variety) in different growing and developing stages, an experiment was carried out in split plot on the basis of Completely Randomized Block Design with three replications in Amole Region in 2008. Main factor was NITROGEN STRESS in three levels (start of tillering, panicle initiation, complete panicle stage and control) and PLANT DENSITY as a sub factor in three levels (80, 120, 160 plant m-2). Results showed that lack of nitrogen use in the start tillering stage caused plant height to decrease and increase panicle number per m2. NITROGEN STRESSes in complete panicle stage caused, a decrease in 1000-grain weight, panicle number m-2 and FOURTH INTERNODES BENDING MOMENT. Plant height, effective tiller per hill and FOURTH INTERNODES BENDING MOMENT were decreased in amount of 6, 9, 46, 3 and 18.7 percent with increased in density until 160 plants per m2 respectively but panicle numbers m-2 was increased 15%. Interactive effects of NITROGEN STRESS with PLANT DENSITY had significant effect on plant height at 5% probability level.
