| Abstract | ||
| Two field experiments were carried out at El-Baramoon Research Farm, El-Mansoura Horticulture Research Station, Horticulture Research Institute, Agricultural Research Center, Egypt during the early summer season of 2014 and 2015 to study the effect of some foliar applications, i.e., moringa leaf extract (50 ml/l), yeast extract (25 ml/l), salicylic acid (150 ppm) and ascorbic acid (250 ppm) on vegetative growth, pod yield and quality of snap bean cultivars, i.e. Bronco, Polista and Valentino.The results showed that Valentino cultivar had longest plant height, heaviest fresh and dry weight, largest leaf area and gave the highest pod length, number of pods/plant and pod yield (ton/fed) compared with other cultivars in the two seasons. Whereas, the least one was Bronco cultivar in both season. Moreover, Bronco cultivar was the highest in pod weight, total soluble solids (TSS) and vitamin C in both seasons, meanwhile Polista pods had the highest fiber and titrable acidity contents. Whereas, the least one was Valentino cultivar in both seasons. All foliar applications significantly increased all the studied parameters compared with the control treatment. The superior application was salicylic acid followed by ascorbic acid in both seasons, respectively. From the obtained results, it could be concluded that Valentino cultivar sprayed with salicylic acid at 150 ppm three times, i.e., 15 days after planting and repeated each 15 days interval, respectively collected the highest total pod yield /fed and quality. | ||
