Sunflower has been cultivated many years in Kerman for seeds; in recent years new varieties has been recommended and cultivated in this region; but many farmers believe local varieties have the least risk for planting dates and market. This experiment was conducted to study and compare new cultivars with local varieties in different planting dates, by using split plot design with randomized complete blocks, and 3 replications. 6 sunflower cultivars: Azar-gol (hybrid), Zaria, Armavirosky, Record and 2 local varieties Jupar (1) and Bardsir (2), were planted in the research station of Agric, College; Univ. of Shahid Bahonar, Kerman on April 20th, May 5th, May 20th; and June 5th in 2003 growing season. The effects of planting date on seed yield, oil, protein, seed diameter, harvest index, 1000 seed weight and dry forage yield were determined. Seed yield ranged from 1443 to 2375 Kg/ha. The May 5th and 20th planting dates, resulted highest seed yield. Oil contents ranged from 36.4% to 43.4% to % the three earliest dates resulted in highest oil contents. Oil yields ranged from 572 to 1991 Kg/ha for planting dates; highest oil yield were from may 5th and May 20th. Dry forage yields were determined; Jupar 3 was/12.1 ton/ha; and Azar-gol was 11.6 ton/ha. Local varieties (1) and (2) had highes head diametens, 1000 seed weight and seeds/head. Infertile seeds were not significant in Azar-gol and (1) and (2); but were significant between these cultivars and others. This study showed that May 5th and May 20th are optimum planting dates in Kerman for highest yield and least risk; considering the good performance of 1 and 2; local cultivars; cultivating these recent cultivars will result high yields and are compatible with new varieties in all agronomic aspects.
