### Effect of Biostimulant Application on Growth Parameters of Snap Bean
In a study conducted by [PERSON] [55] on the effect of adding MLE to watercress (_Eruca sativa_) at a rate of 2%, a positive effect was observed on all parameters of watercress growth. The number of pods, yield of pods per plant, total pod yield per fed, and pod quality (i.e., the length, diameter, and mean fresh weight of pods) per treatment significantly differed in plants treated with the foliar application of biostimulants compared to the control in both seasons (Tables 6 and 7). However, maximum yield values per plant and total yield were obtained with VC tea. The increase in yield with the foliar spray of MLE compared to untreated plants may be due to the increased number of pods per plant, which increased by about 90.6% and 49.9% in the first and the second seasons, respectively. The implementation of MLE not only enhanced the yield quantity of snap beans but also enhanced yield quality. Furthermore, the dry matter percentage in pods in the MLE treatment was significantly increased compared to the control. \begin{table}
