Seed Yielding of Faba Beans (Vicia faba L) Cultivars Grown in Southern Sudan Environment ( Malakal Locality)

Field experiments were conducted in (2004\05 and 2005\06) growing seasons in the Main Campus Farm of Upper Nile University (Malakal), to investigate seed yielding ability of faba bean (Vicia faba L) cultivars, H-93, BB-7 and Sm-L, under the environment of Southern Sudan (Malakal condition). The layout followed was the randomized complete block design with three replications. The 90 plants from these faba bean cultivars were characterized for yield and yield -related components on replicated single plant basis. Significant simple correlations were obtained between seed yield and number of podded nodes, number of pods and number of seeds per plant. Data analysis indicated that total dry matter production, seed weight and number of pods per plant were important in determining yield structure in Malakal. Statistical interpretation showed that number of pods and total dry matter production adequately described yield potential of Malakal grown faba beans. H-93 and BB-7 cultivars had high correlations between primary yield traits and yield reflecting good prospect for substantial yield. Sm-L cultivar was not suitable since its large seed size required longer cooler growing season. Yield and yield related components values were very low because of short winter seasons of Southern Sudan.
