Abstract
The experiment was carried out on an agricultural research farm in Ma’rib Governorate during the 2021-2022 seasons with the aim of studying the effect of four irrigation periods (5, 7, 10, 15 days) and four levels of potassium sulfate fertilizer (50% K2O), 0, 50, 100, and 150 kg/ha., using a randomized complete block design, on the ratio of leaves/stems, number of branches/m2, and green fodder yield (tons/ha) for the sorghum crop Sorghum bicolor L. The results of the research showed the superiority of irrigation periods (7 days) in all the traits studied. The results showed an increase in green fodder yield at irrigation periods (10 days), while irrigation periods (15 days) recorded the lowest value. The results showed significant differences between the potassium fertilization treatments, where the fertilization treatment (100 kg/ha) gave the highest value in the ratio of leaves/stems and the number of branches. And the yield of green fodder. The results showed significant differences as a result of the interaction between potassium fertilizer and irrigation periods. It was found that irrigation periods of 7 days with fertilization treatment (100 kg/ha) were sufficient to cause an increase in the ratio of leaves/stems and green fodder yield, while irrigation periods of 7 days gave With fertilization treatment (150 kg/ha), there was a significant increase in the number of branches..
