Abstract

To study the impacts of NITROGEN DIVISION and time of consumption on the agricultural traits of RAPESEED (OKAPI variety )an experiment was conducted in the factorial design mold based on complete random blocks with two factors and four replications in the farming year of 90-91 in shibloo- Poldasht. The experiment was carried out in three divisive stages of NITROGEN (a1 =50%+50%, a2 = 25%+ 75%, a3+ 75%+25%) and three stages of NITROGEN consumption (b1 = stem growth + flowering, b2 + stem growth + clustering, b3 = clustering + flowering) as the first and second stages. Based on the obtained results, the impact of the time of NITROGEN consumption were significant on the number of cluster, grain yield, oil and harvest index. It was so that in the treatment of NITROGEN consumption as 75 percent in stem growth stage, 25% in flowering stage, the traits of the length of cluster, the number of grains in cluster, the harvest index, grain and OIL YIELD showed the highest amounts, and also the highest grain yield, 3990k.g. per hectare was obtained in this treatment. The least grain treatment, 2790k.g. per hectare was attained in the treatment of NITROGEN consumption in 25% stem growth and 75% of flowering stages. Regarding the results of this assessment of the highest amount of NITROGEN in stem growth and its least consumption in flowering stage can have significant impact on the economy of NITROGEN consumption and reduction of the hazards of erosion.
