### Effect of Biostimulant Application on Chemical Composition of Snap Bean
The application of moringa leaf extract produced the highest linoleic acid content (17.80%), while the yeast extract and control treatments had the lowest linoleic acid content among the accessions. The content of oleic and linoleic acids in the pods was 13.9% and 12.4%, respectively [74]. In the common bean, oleic and linoleic acids were determined to be 7.8-13.8% and 16.7-20.8%, respectively [75]. In that study, the oleic acid content was higher than the current research findings, and the linoleic acid content was higher. The oleic acid content in moringa extract and vermicompost tea treatments was higher (Table 11) than in previous studies. In addition, vitamin C and minerals, including potassium, calcium, magnesium, zinc, copper, and iron, were measured in the snap bean. The obtained results (Table 12) indicate that there were no significant differences (\(p>0.05\)) in any experimental extractions of vitamin C content in snap bean pods. The major amino acid composition of different snap bean protein fractions is shown in Table 13. Leucine and lysine, essential amino acids, had the highest concentrations (7.5-8.2 g/100 g crude protein) on average in snap bean treated with moringa leaf extract, vermicompost tea, and other biostimulants, while glutamic was the amino acid with the highest concentration (13.4 g/100 g crude protein) in the moringa leaf extract treatment \begin{table}
