Abstract:

Linseed (Linum usitatissimum L.) is one of the oil crops cultivated in the highlands of Ethiopia. Its average yield is low largely due to several poor agronomic practices, biotic, and a biotic factor, among which non optimum sowing dates, seed rates, inorganic fertilizer, and improved varieties usages are the major ones. Consequently the field experiment was conducted in Horo Guduru district during the 2019 and 2020 with five objectives: (1) to identify the effect of sowing dates and linseed varieties on yield components, and oil contents. (2) to assess the effect of seed rates and linseed varieties on yield attributes, and oil content. (3) to assess the response of NPS blended fertilizer rates and linseed on growth, and yield attributes. (4) to assess the influence of NPS fertilizer rates and linseed varieties on oil contents and fatty acids compositions, and (5) to estimate net benefit values of seed rates and NPS fertilizer rates. Accordingly, the field experiment was laid out in (a factorial) randomized complete block design (4 SD and 4 varieties) and three times replicated. The analysis of variances on growth parameters, yield component, oil contents, and oil yield were significantly (p
