| Optimum canola planting date in the hot dry climate of southern Iran due to crop rotation, weather condition and soil is very limited, So determine the relationship between yield and yield components with planting date is essential. This research was conducted based on split plot experiment on Compeletly randomized block design by four planting date in main plots and four canola variety in sub plots in three replication. Analysis of variance showed that grain yield, yield components and total dry matter were significantly affected by planting date. Planting date of November 15 was superior characteristics. All under studies Varieties, also in terms of yield and yield components and other traits had significant. Totaly, Hybrid Hyola 401 because of more of leaf area index (3.51), total dry matter (1248.91 g.m-2) and the highest grain yield (2610 Kg.ha-1) in mid-November sowing date in the first priority and if not possible, open pollinated variety of R.G.S 003 on November 6 is recommended. |
