Abstract

In order to study the effect of N levels and optimum plant DENSITY on GRAIN YIELD of RAPESEED cultivar PF7045, a field experiment was conducted in 1998-1999at Ramin Agricultural Research and Education Center, University of Shahid Charmran, Ahwaz. The design was a split plot in a completely randomized block bases with 4 replications. Main plots were consisted of 5 levels of N (45, 90, 135, 180and 225 kgN/ha) and subplots of 3 plant densities (50, 70 and 90 plants/m2). Results showed that higher applications of N fertilizer up to 225 kgN/ha increased GRAIN YIELD (2980.9 kg/ha). The higher yield (2796.4 kg/ha) obtained from 90 plants/m2 denstiy. Interactive effect of N and planting DENSITY on GRAIN YIELD was significant. Application of 225 kgN/ha at the highest DENSITY (90 plants/m2) produced 3301.0 kg/ha of grain. These results indicated that response of GRAIN YIELD to different plant DENSITY was due to differences in N application rates. Among yield components, number of pods/m2 and number of kernel per pod showed that the highest sensitivity to both plant DENSITY and N levels. The number of pods/m2 increased with increase in N levels and plant DENSITY while the number of kernels per pod decreased with increase in N levels and plant DENSITY. 1000 kernel weight increased with N levels and decreased with higher plant DENSITY respectively. The highest of oil (45. 09%) was obtained from 45 kgN/ha at plants/m2 DENSITY and the lowest amount oil (40.0%) obtained from application of 135 kgN/ha at 50 plants/m2 DENSITY. These results showed that the effect of N levels on grain oil was more than plant DENSITY.
