Effects of Varieties, Nitrogen Fertilization and Seeding Rate on Growth, Seed and Oil Yield of Linseed

Sakatu Hunduma


The experiment was carried out for three years from 2016 to 2018 at Wolmera to study the response of different seeding rates and nitrogen fertilizer of linseed varieties. The experiment was arranged in RCBD factorial combination with three replications. Two improved varieties (kassa- 2 and Tolle), three seeding rates (20, 30 and 40 kg/ha) and four Nitrogen rates (0, 23, 46 and 69 kg N/ha) were used. Data was collected and subjected to analysis of variance using SAS/STAT (Windows 9) (SAS Institute, 2004) software. Mean separation was done using list significant difference (LSD test). The analysis of variance revealed non-significant difference for grain yield between the two varieties (p<0.05). Seed rate was Significant to affect grain yield but other parameters tasted were not significantly affected by seed rate. Nitrogen rate had a significant effect on all parameters tasted (p<0.05 except seed oil content. Higher seed yield (1734.9 kg/ha) was obtained by the application of 69 kg N/ha but it was not statistically different from the yield obtained by 46kg N/ha (1722.5 kg/ha). Interaction effect was not significant enough to alter seed and biomass yield. Partial economic analysis revealed that seed rate of 30 kg/ha and 46 kg /ha nitrogen fertilizer rate were the optimum rates for linseed production at the study area.
