Study of some yield characteristics of genotypes of Sudanese millet under different planting dates

A field experiment was carried out in Al-Suwayr district, which is far from the center of Samawa governorate (18 km), In a farmer's field during the spring season of 2022 to study the planting dates for four millet cultivars introduced from Sudan (Ashana, Cardvana, Wedalbasher, Icm77004) The experiment was applied using the split split plots design, according to a Randomized Complete Block Design (R.C.B.D) with three replicates, where the planting dates solved the main panels and the varieties occupied secondary panels, the results of the experiment showed Where the Icm77004 cultivar excelled in weight of one 1000 grains, grain yield, bio-yield and protein content with averages of 7.897 g, 1.565 tons ha1 , 12.297 tons ha-1 and 13.40%, respectively. The first date, March 22, was superior in many characteristics, including grain yield, biological yield, and protein ratio, with averages of 1.466 tons ha-1 and 11.584 percent, respectively. The fourth date, 20 April, was superior in weight of one 1000 grains, with an average of 6.713 g. The interaction between Wedalbasher cultivar on the first date, March 22, grain yield and protein content, with averages of 1.821 tons ha-1 and 11.777%, outperformed the Icm77004 cultivar on the fourth date, April 1, in the trait of the weight of one 1000 grains, with an average of 10.280 g.
