Evaluation of Early Maturing Soya Bean (Glycine max.) Genotypes for Pod Shattering Resistance and High Yielder at Western Tigray, Ethiopia

Pod shattering is occurring after the pods reached maturity which can cause considerable yield loss in soya bean crop. The aims of this study were to evaluate the pod shattering resistance and the performance of the agronomic traits of several soybean genotypes. Field experiment was conducted at Humera district during 2018 cropping season using sixteen soya bean genotypes. Treatments were evaluated with RCBD and replicated three times. Pod shattering, number of branches, seed per pod, pod per plant, hundred seed weight and seed yield was shows a significant (P<0.01) variation among genotypes. While; there was not a significant variation among genotypes in terms of the number of days from planting to flowering and maturity. The mean pod shattering was ranged from scale1.25 to 4. Maximum amount of pod shattering was measured in the genotypes PI423959 (4), PI506764 (3.75) and PI417085 (3.25). However, minimum amount of pod shattering was measured in the genotypes of PI417116 (1.25), Desha (1.75) and PI417132 (2). Highest yield was obtained from the genotypes PI714116 (19.29kg/ha) and PI417132 (16.54kg/ha). However, lowest yield was obtained from the genotypes Williams (check) (6.7kg/ha) followed by PI223963 (8.53 kg/ha) and Nova (check) (9.86 kg/ha).
