Abstract
A significant number of studies have been published on linseed husbandry in other countries but there is limited information on linseed production in the country. Due to such gaps, the experiment was conducted at two locations in Bale, south eastern Ethiopia (Sinana and Agarfa) to study effects of seeding rates and nitrogen fertilizations on linseed performance for three consecutive years (2016-2018). The treatments were four rates each of nitrogen (0, 23, 46, and 69 kg N ha-1), and seeding rates (20, 30, 40, and 50 kg ha-1) laid out in factorial arrangement of randomized complete block design (RCBD) with three replications. Linseed variety ‘Jitu’ was used as a test crop. The main effect of nitrogen and seed rates at Sinana was not significantly affected (P<0.05) most of the studied parameters probably due to relatively high accumulation of nitrogen in the soil and conducive environmental condition. However, the study conducted at Agarfa using similar methodology was significantly affected by the studied factors. This could be due to low to medium soil nitrogen status of the study site. Accordingly the result of the experiment at Agarfa revealed that applying 23 kg N ha-1 (50 kg ha-1UREA) when 20 kg ha-1 seed rate in row planting were given the highest marginal rate of return. However further investigation has to be carried out on farmers’ field in order to further confirm the present results.
