ABSTRACT

Soybeans (Glycine max Merrill) genotypes G1(1904 E) and G2 (1905 E) were planted on five sowing dates: S1(2 June), S2(9 June), S3(16 June), S4(23 June), and S5(30 June) for two seasons ( 2009/10-2010/11). The experiments were conducted in split plot design, in semi-desert region in Sudan. In season 2009/10 the result showed that S4 (23 -June) and S5 (30-June) obtained the lowest values of yield components. The results of season 2010/11 showed significant differences for number of pods/plant, number of seeds/pods and highly significant difference was obtained in weight of pods/plant, weight of seeds/plant, 100seed weight, yield and harvest index. The S3 (16-June) mid June, obtained the highest values and S5 (30- June) gave the lowest values of the above parameters. There were no significant differences between two genotypes of all parameters of yield and yield components except weight of seeds/plant, yields and harvest index. Genotype G1 (1904 E) showed the highest values. The interaction of different sowing dates and two genotypes of soybean were showed no clear differences. In conclusion, the sowing date in mid June is the best sowing date, and sowing date in late June must be avoided due to reduction in yield and yield components.
