An Evaluation on Cultivation Process of Soya Bean Varieties for Yield and Shattering Character at Moisture Stress Area in Western Tigray, Ethiopia

Aim of the current study was to evaluate released soya bean varieties for seed yield and shattering properties at moisture stress area under field condition. Field experiment was conducted at Humera district during 2017 cropping season using sixteen released soya bean varieties. Treatments were evaluated with RCBD and replicated three times. Number of days from planting to days of flowering and days of maturity, number of pod per plant, pod shattering and seed yield were showed a significant (P<0.01) variation among varieties. While; Seed per pod, hundred seed weight, seed moisture and number of branch per plant weren.t significant difference among the varieties. All varieties were resistance to pod shattering except AFGAT (18.5%) and tgx-1332644 (27.5%) were moderately resistance and moderately susceptible, respectively. Heights seed yield was recorded from the varieties Awassa-95 (14.92kg/ha) followed by Cocker (14.89kg/ha). Lowest seed yield was recorded on the varieties Belesa-95 (8.01kg/ha) and tgx-1332644 (8.96kg/ha). Association showed that there was a significant positive and negative association of among yield and yield component. The strongest correlations are obtained between date of flowering and branch per plant. In addition, hundred seed weight was positively correlated with both pod per plant, seed per pod and plant height. It was concluded that the high yielder and early-maturing (Hawassa-95 and Cocker) varieties are suitable for the lower rainfall distribution areas to improve the soya bean production and productivity.
