The objective of this study is, therefore, to evaluate the effects of row spacing and seed rate on yield and yield components of linseed. Materials and Methods: A field experiment was carried out to evaluate the effects of seed rate and row spacing on the yield and yield components of linseed, during 2017/2018 cropping season at Dabat district of Northwestern Ethiopia. KULUMSA1 (CHILALO) was used as test crop. Factorial combinations of three-row spacing, (20, 25 and 30 cm) and three seed rates, (40, 45 and 50 kg) were laid out in RCBD with 3 replications. Data regarding different parameters were recorded. Results: The main effect of seed rate was highly significant for days maturity, thousand seed weight and harvest index. Moreover, it was significant for days to flower and number of capsules per plant. The main effect of row spacing was significant for days to maturity. The interaction of seed rate and row spacing were highly significance for a number of primary branches per plant and seed yield. Highest seed yield (1771 kg ha1) was obtained at seed rate of 40 kg ha1 with 25 cm of row spacing Therefore, seed rate of 40 kg ha1 with 25 cm of row spacing are recommended to increase yield and yield components. Conclusion: In conclusion, the effect of seed rate and row spacing affects the important yield components of linseed.]]>Fanta, E.G.,20052005Wijnands, J.H.M., J. Biersteker and R.
