Abstract
A two years field experiment was conducted during 2012/2013 and 2013/2014 winter seasons at Agricultural Research Station, Alexandria University, to study the effect of three seeding rates (30,45 and 60 kg/fed.) and eight weed control treatments on agronomic characters of flax cultivar Sakha 4 and its companion annual weeds. Increasing seeding rates had insignificant effect on broad, narrow and total weeds dry weight in the two seasons. Application of a combination of Brominal and Select Super was superior to hand weeding twice and individual application of pre-emergence or post-emergence herbicides in reducing both categories and total weed dry weights. As seeding rate increased plant height, technical length, seed and biological yields increased significantly from the lowest to the highest seeding rate, whereas number of capsules per plant, 1000 seed weight, fruiting zone length, number of basal and apical branches and seed yield per plant were significantly decreased. Application of post-emergence herbicide combination of Brominal + Select Super gave significantly improved values for seed yield and yield components compared to individual herbicide application, pre or post-emergence, and was comparable or superior to hand weeding twice in both seasons.
