Effect of some agronomic practices on sunflower production 2-planting date and planting distances on yield and its component of some sunflower cultivars



Effect of some agronomic practices on sunflower production 2-planting date and planting distances on yield and its component of some sunflower cultivars



Annals of Agricultural Science, Moshtohor 30(1): 109-126



In field experiments at Abo-Sweir, Ismailia in 1986 and 1987 sunflowers Maiak, H7116 and H7780 (1986) and H7107 (1987) were sown at densities of 23 333, 29 167, 38 888 or 58 333 plants/feddan. Sowing dates in 1986 were May, July, Aug., or Nov., and in 1987 Apr., June or July. In 1986 seed yields were greatest with May sowing, H7116 giving 1603 kg/feddan, H7780 giving 1595 kg and Maiak giving 1717 kg.
