Effect of Spraying Salicylic Acid and Seeding Rates on Wheat Plants under Water Stress

Abstract

An experiment has been done in a flowerpot for the study of seeding effect and on salicylic acid on the production of wheat under moisture tension by using the system of split bars once, and tri-repeated Random Complete Block Design (RCBD).So, the whole or main plots has included irrigation treatments irrigation (every 7, 14, and 21 days), whereas the has included the averages of seeding (60, 80) kg. ha-1),and the sub-sub-plots has included sprinkle plants with ordinary water (comparison treatment),and with the salicylic acid by concentration of (0, 100 and 200) ppm. Results have indicated that; the plants which were irrigated every 7 and 14 days are high-level average (32.31and 36.61) .cm, the area of a flag –leaf is ( 31.87and34.20 ) cm2, the seeds amount is (28..31 and 29.84) seed.pike-1), the protein rate is 21.96and 23.91)% but plants –which where irrigated every 14 days –have surpassed move spikes (4.43 spike.m2) and thetotal wheat is (6.40 ton. ha-1), the treatment has given (60kg. ha-1),the higher value of seeds weigh is (0.44gm. plants-1).results of the study have showed the surpassing irrigation treatment and besides seeding treatment (12 day and 60kg. ha-1) at the production features and their components with the exception of the dry weigh which hasn't indicated differences .Additionally, the study results have showed the surpassing concerns traction of salicylic acid (100 ppm)at the studied production features with the exception of the length of a spike (200) and recorded (5.50cm). Finally, the results were revealed possibility using salicylic acid during fertilization stage, and it helps to increase seed yield and oil percent.
