Nitrogen content in the seedlings of wheat as parameter for selection on nitrogen fixation

Abstract

Three cultivars of spring wheat (KG1103, KG1203 and KG1303) were inoculated with seven different strains of diazotrophs (Dd1, Dd2, Dd3, Dd4, Dd5, Dd6 and Dd7) and mixed population (Dd9). Influence of inoculation was analyzed on the some components of grain yield and grain yield. Influence on inoculation with diazotrophs indicated very significant differences in majority investigation parameters. The highest grain yield was found in cultivar KG1303. The highest effect of inoculation with diazotrophs has got with strain Dd1 and association between Dd1 and KG1103 was most effective. However, in the case interaction genotype-strain, association KG1303 and Dd1 showed the highest values.
