Physiological Analysis of the Growth and Development of Canola (Brassica napus L.) Under Different Chemical Fertilizers Application

Esmaeil Yasari and A.M. Patwardhan
A split-plot experimental design with nine treatments and a non-fertilizer application control plot in 4 replications was carried out during the 2004-2005 growing season, at the Baiecola Agricultural Research Station in the Mazandaran province of Iran. Canola (Brassica napus L.) was grown as a second crop in rotation after wheat and its seed yield, growth parameters (CGR, LAI, RGR and NAR), dry matter accumulation and HI was examined. N P K fertilizers together with S and Zn, singly or in combination were applied, before the sowing and after examining the soil requirement. The maximum yield (3141.250 kg h-1) and TDM (6498 kg h-1) and seed oil content (45.83%) were obtained at T10 (NPK Zn), coinciding with 203 pods/plant and 120.53 cm plant height. The application of NPKS at T9 resulted in the maximum seed protein (24.25%). Maximum LAI was recorded during 83 to 111 DAS period for all the treatments coinciding with the highest LAI value at T10 (4.8) which was followed up by the T9 and T8 having 4.61 and 4.56, respectively. The maximum value of CGR resulted at flowering (112-133 DAS) in which the T10, T9 and T8 showed the maximum value of CGR having 16.313, 15.770 and 15.373 (g m-2 day-1), respectively. The optimum LAI of canola plantation for the area in the study year was 4.26 which obtained at T10 during flowering. The RGR and NAR also were affected by the treatments, though not so much effective for RGR, the maximum NAR resulted at T9 quite resemble to those of T8 and T10 during the flowering stage.
