Abstract

A field experiment was conducted to evaluate the effect of NITROGEN and cycocel (2-chloroethyl trimethyl ammonium chloride), CCC application on yield and yield components of two oilseed rape cultivars (cv. Talaye and Likord). The study was conducted under Badjgah (52° 46’ N, 28° 50’ E) agroclimatic conditions at the college of Agriculture, Shiraz University, Shiraz, Iran during 2004-5. The design of the experiment was a split-split plot with four replicates. There were two cultivars (Talaye and Likord) in main plots, four NITROGEN levels (0, 50, 100, 200kg/ha) in sub-plots and three GROWTH RETARDANT rates (0, 1.4, 2.8 CCC L/ha) in sub-sub plots. The results showed that the highest seed yield in Talaye and Likord was achieved when 200 kg N/ha was used. Increase in NITROGEN application was associated with increased dry matter produced, and number of siliques/plant. Number of seeds per silique, and mean seed weight were among the most stable components of yield and did not show any significant changes. Likord oil and protein percentage was highest at 100 kg N/ha and is recommended to be followed up in future investigations. Application of cycocel at 2.8 L/ha enhanced the number of siliques/plant, seed yield and dry matter produced. In addition, cycocel application at 200 kg N/ha increased the seed yield/m2. Cycocel application at the rate of 2.8 L/ha and 200 kg N/ha in both cultivars might be recommended for similar agroclimatic conditions.
