Abstract :This study was established as a pot experiment with 4 replicates according to the coincidence plots factorial experimental design to investigate the positive and negative effects of sodium clor (NaCI) salt and leonardite material doses prepared at different rates on the development of NC-7 groundnut variety in the summer season of 2021. 5 different leonardite doses (0 kg/da, 25 kg/da, 50 kg/da, 75 kg/da and 100 kg/da) and 4 different NaCI doses (0 mM, 50 mM, 100 mM and 150 mM) were applied. As a result of the study; plant height 10.06-12.36 (cm), number of branches 3.00-3.78 (pcs/plant), seedling wet weight 5.66-8.94 (g), seedling dry weight 4.42-7.27 (g), leaf area index 36.62-47, 53 (cm2), root length 26.31-45.93 (cm), root wet weight 0.44-2.52 (g), K content 0.957-1.337 (%), sodium (Na) content 386.25-699.05 (mg/kg). According to the data obtained in the experiment; NaCI salt application had a significant effect on seedling dry weight, seedling wet weight, Na and root wet weight. Leonardite application had significant effect on plant height, root length, potassium (K) and root wet weight. Leonardite x NaCI interaction had significant effect on root length, root wet weight, seedling dry weight, K (%) content and Na (mg/kg) content.
Keywords : Peanut (Arachis hypogaea L.), leonardit, NaCI, salt stress.
