Abstract

In order to evaluate the effect of different levels of nitrogen fertilizer and plant DENSITY on competetiveness of RAPESEED with weed, an expriment was carried out in 2008 at Marvdasht, Naghshe Rostam in Fars. The expriment was conducted in factorial arrangement on the base of RCBD with 3 replications. The treatments were a combination of 4 planting densities (50, 80, 110 and 140 plant/m2) and the amount of applied nitrogen fertilizer as the suggested rate, (330 kg/ha), 30% more than the suggested rate (430 kg/ha), and 30% less than the suggested rate (230 kg/ha). The results showed that the grain yield, pod number per plant, the thousand seed weight, total number of weeds and weeds dry weight were affected with DENSITY but just weeds dry weight was affected by nitrogen fertilizer. Results showed that the highest grain yield was obtained in DENSITY of 110 plant/m2 and the use of 330 kg/ha of nitrogen fertilizer, the highest pod number per plant was in DENSITY of 50 plant/m2 and the use of 430 kg/ha of nitrogen fertilizer, the highest thousand seed weight was in DENSITY of 110 plant/m2, the highest number of weeds was in DENSITY of 50 plant/m2 and the highest weeds dry weight obtained was in DENSITY of 50 plant/m2.
