Abstract

During the 2021–2022 winter growing season, an experiment was carried out in two distinct locations: Field Crops Department Research Station-College of Agriculture and Forestry and Wana sub-district. The study aimed to investigate the influence of 3 levels from nitrogen fertilizer (0 , 75 , 150 kg N/ ha) and 3 zinc rates (0 , 20 , 40 mg/L) on the growth, and flax production (Linata variety). It was factorial experimentation with two factors set in a split-plot design within (RCBD) with three blocks. Main plots included 3 levels from nitrogen fertilizer, while sub-plots included 3 zinc rates. The results showed that the 75 kg N/ha fertilization level significantly outperformed in seeds number/ capsule , capsules number/plant, 1000-seed weight , seed yield, oil percentage in seeds and oil yield in locations the College and Wana, respectively. Meanwhile, 150 kg N/ ha fertilization level excelled in plant height and branch number/ plant for locations. The data also showed that the 20 mg/L zinc concentration significantly outperformed in plant height, branch number/plant, and oil percentage in seeds. Conversely, the 40 mg/L zinc concentration excelled in seeds number/ capsule , capsules number/plant, 1000-seed weight , seed yield and oil yield in both locations. Moreover, there was a significant interaction between the 75 kg N/ha fertilization level and the 40 mg/L zinc concentration in capsules number/plant at the Wana location, and seed yield for locations, respectively.
