Abstract

In order to evaluate the effects of different levels of silic spraying and plant DENSITY on quantitative characteristics of hybrid Hyola-42 in RAPESEED (Brassica napus), afield experiment was conducted in field research (Galea sien) in Collage of Agricultural of Varamin, in 2007-2008 cropping season. The experimental design was arranged factorial in a randomized complete block design with three replications and 27 treatments. In this research plant DENSITY was in three levels: 500, 650 and 800 thousands plant per hectar. and Silic spraying concentration were in three levels, consisting non- spraying (control), spraying of silic with 3 6 per thousantds. The results showed grain yields has a straight correlation with yield components. Increase and decrease yield components is reason of changing of total yeild. The highest grain yield was obtained from Silic spraying with 6 per thousand with average yield 3372.3 Kg/ha. This treatment had 28.9 percent increase yield in ratio with control treatment (with 2400 Kg/ha). Also highest of plant height, Number of branch, number of silique per plant, number of grain per silique, 1000 grain weight and biological yeild with 136.1 cm, 4.3, 188.3, 17.3, 3.34 (gr) and 7822.6 Kg/ha was obtained from silic spraying with concentration 6 per thousands. In this research plant DENSITY showed significant differences on characteristics of experiment . The highest grain yield was obtained from DENSITY (800 000 plant per hectar) with average yield 4351.3 Kg/ha. The lowest grain yield was obtained from DENSITY (500 000 plant per hectar) with average yield 2343.3 Kg/ha. The results of extraction effect showed that there were significant defferences among plant DENSITY and Silic spraying on this adject at 5%, 1% levels. The highest plant height, Number of Silique per plant, grain yield and biological yield from treatment DENSITY and Silic spraying (800000plant per hectar and 6 per thousand). at last this result was known DENSITY and silic spraying (800000plant per hectar and 6 per thousand) is recommender for Varamin condition.
