Abstract

Abstract A field experiment was held during winter season of 2022 at two sites in the Research Station of the Field Crops Department - College of Agriculture and Forestry which is located at 43° 9’ east longitude and 36° 21’ north latitude, and in the Badush Dam area which is located at 42° 58’ east longitude and 36° 28’ north latitude, with the goal of figuring out the effect of two factors on the productivity of flax (Linata variety), namely late planting dates and harvest dates. A randomized complete block design (RCBD) was utilized to design experiment with two factors: the first three sowing dates (15/1, 5/2, 25/2/2022) and the second three harvest dates (120, 135, 150 days after planting) and in three sectors. The results displayed significant differences between late planting dates in all studied traits except for the seeds number per capsule and oil content in seeds in both sites and the weight of 1000 seeds in the Badush Dam site. The late planting date 15/1 gave the highest average plant height, branch number per plant, capsule number per plant, individual plant yield, seed yield, and oil yield in both sites, while the date 25/2 was superior in the weight of 1000 seeds in the college site. Harvest dates had a significant effect on some studied traits in both sites, as harvest date of 135 days after planting recorded the highest values for plant height, branches number per plant, capsules number per plant, individual plant yield, seed yield, oil content in seeds and oil yield in both sites. The interaction between late planting dates and harvest dates was significant in some traits at both sites. Plants planted on 15/1 and harvested on 135 days after planting recorded the highest results for the traits of seed yield at both sites and the capsules number per plant at the Badush Dam site.
