Fenugreek Performance Affected by Foliar Application of Gibberellin and Arginine Acids

A field experiment was carried out during the winter season of 2020-2021 in a farmer’s field - Zakhikha area - Heet district/Anbar Province, Iraq to find out the effect of four concentrations of GA3, arginine acid and the interaction between them in some growth indicators of fenugreek plant Trigonellafoenum graecum L. Split plots via randomized completely block design were used with three replicates. The main plots included GA3 concentrations (0, 100, 200 and 300 mg L-1), while the sub plots included arginine acid concentrations (0, 100, 200 and 300 mg L-1). Results showed that the concentration of 300 mg L-1 for both factors gave a significant increase in plant height, number of branches, plant dry weight, number of pods, 1000 seeds weight and seed yield. Interaction effect between two factors had not a significant effect on all traits except the seed yield which gave an increase rate of 66.53% over the control treatment.
