Effect of Spraying with Glycerine Taine acid on the Growth and Yield of Sesame under Conditions of Salt Stress

The sanadin experiment was carried out in the agricultural season of 2023 at the site of the faculty of agriculture - anbar university. For the purpose of studying the effect of spraying with glycine betaine acid on the growth and yield of sesame under conditions of salt stress, according to the design of complete random sectors.c.b.d in the order of splinter plates and with three repeaters. The experiment included two factors, the first factor was the levels of salt stress with three salt concentrations of sodium chloride (nacl): 1.5, 3 and 4.5 decisimens m-1, as well as the measurement treatment (distilled water) and a code for these coefficients in the codes s1, s2, s3 and s0 respectively, the main panels were switched on. The second factor was spraying with three concentrations of glycine betaine acid: 50, 100 and 150 mg l-1, as well as the metering treatment (distilled water) and its code gb1, gb2, gb3 and gb0 in succession, which occupied the secondary plates.the results showed the superiority of salt stress treatment (S0) in most of the studied attributes : plant height, leaf area, seed yield, biological yield, harvest guide. The results also showed the superiority of the spray treatment with glycine betiane gb3 acid in all the studied qualities mentioned above. The results also recorded the presence of significant differences between the interference coefficients conclude from this study that irrigation of plants with high levels of salt stress has reduced the seed yield of the Sesame crop and the addition of high concentrations of glycine Betaine acid has somewhat mitigated the effect of salt stress, especially at low levels of salinity, and therefore it is possible to use water with low salt concentrations in the irrigation of Sesame crop and using Glycine irrigate it with low-salinity water.
