Effect of salt tensile when using a salinity processor for oat genotypes Avena sativa L. in gypsum soil

الملخص EN

This study was conducted in the fields of the College of Agriculture, Tikrit University for the season 2019-2020 to study the effect of salt stress (0.5, 2.75 and 5 EC) and salinity treatment (0 and 0.006 mm) in six oats genotypes (Alguda, Icarda short, Anotolia, Icarda tall).

The experiment was applied with a randomized complete block design RCBD with a split split plot system with three replications, Five traits were studied: the number of active tillers m-2, the number of grains per panicles, the weight of 1000 grains, the grain yield, and the biological yield ton.

ha-1.

The effect of salt stress negatively on each of the number of grains in delta, grain yield, and biological yield, The use of the saline treatment also improved both the number of active tillers, the number of grains in the panicles, the weight of 1000 grains, the grain yield and the biological yield.

The genotypes differed in their performance for the studied traits, where the genotype G3 excelled in the number of tillers.

m-2 (447.4) and the number of grains in the panicles (29.72), the weight of 1000 grains (31.43 g), and the grain yield (4195.7 kg.

ha-1) on the rest of the other compositions.
