| Abstract | ||
| In order to investigate sowing date and cultivar effect a split –plot design was arranged in randomized complete block with four replication carried out in natural resources research station of kerman research center. Main plots were included four sowing dates (15Mar and 30Mar and 14Apr and 29Apr) and sub plots were included three cultivars (Cv.kerman, arak 2811,Esfahan native). From planting to total growth stages the following parameters (seedling, stems, bottom, flowering, and maturation) were effected with plant date and were reduced with delay in planting. Effect of plant date on plant height, sub branch number, heads per plant, seed weight, dry weigh of plant, seed yield and flowering, oil, and protein yield was significant and all of them reduced with delay in plant. Seed protein percent was increased with delay in planting and also seed oil increased with acceleration in early planting. The results showed that interaction between plant date and cultivar on plant height, sub branch number, heads per plant, seed number per heads, seed weight, biological yield, seed yield, oil yield, protein yield, percent of protein and oil was significant but in harvest index wasn’t significant. The second plant date 30March and CV.kerman are suitable for seed yield and Esfahan native cultivar is suitable for seed oil and recommend for planting and producing in Kerman climate condition. | ||
