Abstract
The present research is carried out at the Farms of Agricultural Secondary School in AL Salamieh city, Hama Governorate, Syria, during the season 2015 to evaluate the productivity of three sweet corn varieties; one was local variety, Faihaa1; and two Ukrainian varieties; Randevo F1 and Snekofa Karaliva F1 under the effect of different planting dates (1st and 15th April) in order to determine the best variety and the most suitable planting date in spring season. The results showed that the grain yield and yield components of Faihaa1 variety were higher than that of Randevo and Snekofa Karaliva in the first planting date (1st April). The increase of grain yield recorded were (3.38-2.86-ton/ha), and fresh ears yield with husks recorded were (1.88-0.58-ton/ha) respectively. Also, the results showed that there was significant increase in number of ears per plant, number of grains per ear and ear grain weight of Faihaa 1 variety compared to Randevo F1 and Snekofa Karaliva F1. And grain yield and yield components of Faihaa 1 were higher than Randevo F1 and Snekofa Karaliva F1. The highest grain yield was at the beginning of April for all varieties, and the fresh grain yield recorded was (9.01) ton/ha. The fresh grain yield and other productivity characters decreased on mid-April for all varieties. The results showed that there was significant increase in the productivity characters in Faihaa 1when it was planted at the beginning of April.
