Abstract

Early to late June on the red and light soils of the central, southeastern and northwestern zones, and early to mid July on black clay soils of the regions are the optimum sowing dates for linseed. Similarly, for Brassica the optimum dates were three weeks before the commencement of a steady rain for the central and lower altitude (below 2500 m) areas of the southern and southeastern zones and late May for the higher altitude (above 2500 m) areas of the southeastern zone. For linseed, a seed rate of 25 kg/ha had a slight advantage on red and light soils and 20 per cent more on black clay soils. For Brassica, 6-10 kg/ha seed rate was found optimum depending on weather conditions, lower rates being appropriate when shortage of rain during the critical growth period is anticipated. Equally good seed yields of both linseed and Brassica were obtained from the broadcasting method. However, to ease management a row spacing of 40-50 cm is reasonable. As linseed is a poor competitor to weeds, it needs a clean, firm and more uniform seedbed. Cropping sequence results indicated that higher yields of wheat, tef and barley were obtained when they followed linseed. The same was true with rapeseed although the increases were not as high as in linseed.
