Influence of seed rate and row spacing on seed multiplication factor and yield of durum wheat in Ethiopia

Optimum seeding rate and row spacing are important for uniform crop establishment harvest of quality seed. Field experiment was conducted at three locations in 2014 2015 to study the influence seed on multiplication factor yield durum wheat. Triplicate split plot design used. The highest found a 125 kg ha−1 with 10 cm but not significant rates 100 spacing, 75 20 2014, 150 Debre Zeit. At Chefe Donsa, (4.75 ton) harvested ha−1. Minjar, affected by rate. Seed higher 50 ratio (97.3) observed 30 cm. decreased increasing all testing locations. Sowing seeds per hectare gave optimum over With limited availability nucleus seed, is appropriate upsurge ratio.
