Abstract

This experiment was conducted to study the effect of different IRRIGATION LEVELS on YIELD and water use efficiency (WUE) of four varieties of RAPESEED in Karaj during 2003-2004. The experiment was a randomized split-plots as complete block design with three replications. IRRIGATION LEVELS including, 50, 75, 100 and 125 percentage of water requirement were considered as a main plots and four varieties: Licord, SLM046, Okapi and Reg Cobra as sub plots. The water requirement calculated on the basis of meteorolgicale data using Penman-Monteith method. ANOVA and averages comparison indicated as blow: IRRIGATION LEVELS, varieties and interaction effects were not significant at 5% on plant height. IRRIGATION LEVELS effect was significant at 5% level on branches numbers per plant. The interaction effects were significant in 5% level on seeds number per pod. The IRRIGATION LEVELS and varieties effects were not significant at 5% level on 1000 seed weight. The effect of IRRIGATION LEVELS and varieties on gratin YIELD were significant at 1% level. The irrigation with 75% water reopurement 2727 kg/ha YIELD was maximum and the level of 50% with 1912 kg/ha was minimum respectively. Although, Reg Cobra variety with 2783 kg/ha and Licord variety with 2132 kg/ha were maximum and minimum respectively. The interaction effects were significant at 5% on seed YIELD. The 75% Irrigation level in variety Reg Cobra with 3229 kg/ha and the 50% level in variety Licord was minimum of YIELD. The IRRIGATION LEVELS and variety effects on WUE was significant at 1% level. The 75% level with 1.114 and the 50% level with 0.684 kg/m3 were maximum and minimum respectively.Water use efficiency of level 75% was 62.86% more than level 125% with 99% probability. Reg Cobra variety with 1.064 kg/m3 and Licord variety with 0.826 kg/m3 were maximum and minimum respectively. Water use efficiency of Reg Cobra variety was 28.8% more than of Licord variety.
