EFFECT OF MOISTURE CONTENT AND SPRAYING WITH ZINC IN THE YIELD OF SEEDS AND OIL OF THE BORAGE PLANT (Anchusa azurea)

the experiment was conducted in the greenhouses of the winter season 2016 - 2017 in Diyala Province using a factorial experiment according to Randomized Complete Blocks Design (RCBD), to study the effect of three levels of moisture content (50, 70 and 90%) of the field capacity and two treatments of spraying with zinc (0, 200 mg.L-1) in the leaves number, dry plant weight, 100 seed weight, plant seed yield and oil percentage in seeds. The results showed that the water content at (90%) of the field capacity led to a significant increase in the leaves number, dry plant weight and plant seed yield, which reached (15.5 leaves, 38.06 g.plants-1, 2.01 g.plants-1), respectively. While led the irrigation at moisture content (70%) of field capacity to significantly increased the weight of 100 seeds and oil percentage of seeds was 2.00 g and 29.80% respectively, In addition, the spraying of zinc produced a significant increase in all the studied indices (14.67 leaves.plants-1, 37.75 g.plants-1, 1.96 g, 2.05 g seeds.plants-1, 29.43% oil).There was also a significant bi-interaction between the factors above, The treatment of the mixture (90% of the field capacity with spraying with zinc) gave a significant increase in seed yield and oil percentage in seeds (2.21g seeds.plants-1, 30.01%) respectively
