Effect of row spacing on light interception, grain yield and growth indices of rapeseed (Brassica napus L.) cultivars as second crop following rice
Abstract:   (3778 Views)
Effect of row spacing on grain yield and variation in growth indices of rapeseed (Brassica napus L.) cultivars as second crop following rice was investigated in a paddy fields at Rice Research Institute of Iran (Rasht), in 2003-2004 and 2004-2005 growing seasons. The experiment was conducted as a split plot in randomized complete block design with four replications. The main plots consisted of four rapeseed cultivars: Hyola308, RGS003, PF7045/91(Sarigol) and Hyola401 and the sub-plots were three row spacing: 20, 25 and 30 cm at constant plant densities (40 plant/m2). Results showed that PF7045/91 (Sarigol) ranked the first in relative growth rate (4.29 g/g.10GDD), crop growth rate (9.25g/m2.10GDD), leaf area index (1.89) and net assimilation rate (15.89 g/m2.10GDD), grains yield(2043 kg/ha) and oil content (34.19%) was significantly different with the other cultivars. Hyola308 ranked the last among cultivars. Row spacing of 20 cm ranked the first in relative growth rate (4.28 g/g.10GDD), crop growth rate (6.98 g/m2.10GDD), leaf area index (1.706), net assimilation rate (10.25 g/m2.10GDD), grains yield (1777 kg/ha) and oil content (33.35%) and were significantly different from other row spacings in LAI and NAR indices. Results also showed that PF7045/91 (Sarigol) ranked the first in light interception (LI%) and Hyola308 ranked the last (75.5% and 61.5%, respectively). Row spacing of 20 cm ranked the first in light interception (68.5%). Therefore, PF7045/91 (Sarigol) ranked the first in relative growth rate, crop growth rate, leaf area index, and net assimilation rate, grains yield, oil content and light interception. Row spacing of 20 cm also ranked the first for these traits.
