The impacts of implementing different water requirements strategies (STs) and applied cobalt applications combined with ground drench applications of Kh on the (A) Oil in seeds, (B) Protein, and (C) Carbohydrates in peanut seeds in two seasons of 2021/2022. Data represent the mean of three replicates of both the years of 2021 and 2022. Error bars indicate standard errors from the mean. Bars with different letters are statistically significant at p ≤ 0.05. Abbreviations: Control, spray with pure water; Kh (applying soil application of potassium humate at two rates 2 and 3 g l−1); and Co (applied two equal doses of cobalt by (3.25 mg l−1 for the dose), injection in the irrigation water).
