Abstract

The experiment was conducted at agricultural research station of Gonbad during 2001 - 2002. The experiment was a factorial split arranged in a randomized complete block design (RCBD) with 3 replications. Three IRRIGATION treatments (1- without IRRIGATION, 2- IRRIGATION at flowering stage and 3- IRRIGATION at flowering and seed filling stages) and two varieties (Sarigol and Hyola 401) were as main plots in a factorial arrangement. Three NITROGEN treatments (1- without NITROGEN applying, 2- NITROGEN applying without foliar application and 3- NITROGEN applying with foliar application) were subplots. The effect of IRRIGATION was significant at 1% level on the number of days from emergence to physiological maturity and 1000-grain weight level and on grain yield and oil at 5% level. IRRIGATION at flowering and seed filling stages increased grain yield, significantly, whereas there was no significant difference between non-irrigation and IRRIGATION at flowering stage treatments in grain yield. The effect of IRRIGATION, NITROGEN and VARIETY did not significant on oil percentage. Plant height, 1000-grain weight, grain yield and oil of Hyola 401 Hybrid were more than those of Sarigol VARIETY. The effect of NITROGEN was significant at 1% level on the pre winter growth, the number of days from emergence to flowering, Plant height, 1000-grain weight, grain yield and oil. The number of pod per plant and the number of grains per pod were affected by NITROGEN application. Soil NITROGEN application increased grain yield, significantly, while the effect of foliar NITROGEN application on grain yield was not significant.
