Effect of Methyl Jasmonate Spraying on Growth and Yield of Vicia faba L. Plant

This agricultural experiment was conducted in the Department of Life Sciences' plant house at the University of Diyala's College of Education for Pure Sciences. In order to investigate the effects of spraying methyl jasmonate at five different concentrations—0, 25, 50, 75, 100 mg. Plastic pots that could hold 7 kg of mixed soil were used in this experiment to produce bean plants. Three replications and a completely randomized design were used in the experiment's design. At a 0.05 level of probability, the means were compared. Two seeds were put in each pot after the soil had been prepared and cleaned of impurities. The germination rate was 100% at the beginning of the experiment, but seven days later it dropped to one plant. Two sprays of varying concentrations of jasmonate were applied to the plants; the first was one month after germination, and the second was one month following the first. Since the concentration of methyl jasmonate exceeded 25 mg L-1 in every characteristic examined, the results demonstrated that there were distinct variations between the various quantities of the molecule. Plant height, stem diameter, number of leaves, number of branches, number of pods, weight of pods, and number of seeds in pods are some of these attributes. 60.40 cm, 7.73 cm, 27.33 sheets were attained. Branch 3.02 of Plant 1. 2.33 pods per plant. Plant-1, 6.33 seeds, 11.01 g. Pod-1, in turn. On the other hand, 75 mg was the stated concentration. In comparison to the control treatment, L-1 exhibits lower averages for the majority of the attributes. Highlights: Experiment tested methyl jasmonate effects on Spanish bean plants' growth. Five concentrations: 0, 25, 50, 75, 100 mg L⁻¹ evaluated. Results showed optimal growth at 25 mg L⁻¹, decline at 75 mg. Keywords - Beans plant; Methyl Jasmonate; Field crops; Vicia faba
