Abstract

The present study was conducted during the growing season 2015/2016 and 2016/2017 in medicinal and aromatic plants field of the College of Agriculture/ Basrah University, to study the effect of sowing date 1/11, 1/12 and spraying with Ascorbic acid 400mg. L-1 or without (spraying with distil water) after 30 and 60 day from planting and their interaction on growth and seed, oil yield of flax plant (Linum usitatissimum L.).      

The results showed Cultivated plants on 1/11 had a significant increases in plant height, number of main vegetative branches.plant-1, leaves number. plant-1, length and weight of root system, Seed yield. plant-1, seed yield. unit area-1, oil percentage, oil yield. plant-1, oil yield. hectare-1 for both seasons, seed yield. hectare-1 in second season only.

Spraying with Ascorbic acid 400 mg. L-1 give significant increases in, leaves number. plant-1, length of root system for both seasons, plant height, weight of root system, weight of 1000 seed, oil percentage in second season only. oil yield. plant-1 in first season only.

The interaction between first sowing date and spraying with Ascorbic acid gave highest in leaves number. plant-1, highest percentage of the dry matter of the vegetative total, length and weight of root system, seed and oil yield. plant-1, seed yield. unit area-1, oil percentage and seed and oil yield. hectare-1
