Abstract
The present work was carried out during two successive summer seasons of year 2005and 2006 in unheated plastic house at the Experimental Station, Faculty of Agriculture, Cairo university, Giza, to study the response of two snap bean (Phaseolus vulgaris,L.) cultivars, namely Bronco and Pulista to nitrogen application time i.e., three times or twice or adding nitrogen one time and foliar stimulants, i.e., Faster and Setter-2 . The experiment included 32 treatments which were a combination of two cultivars, and sixteen combination treatments between four nitrogen application time and four foliar biostimulants. There were no significant differences between the two cultivars, i.e., Bronco and Paulista, regarding vegetative growth characters, except Paulista cv. Which exceeded Bronco in the number of branches in the first season. Adding nitrogen in three doses, i.e., 25% at soil preparing + 50% three weeks after planting + 25% at flowering, significantly increased number of branches per plant in the first season, as compared with adding nitrogen once, three weeks after planting. Foliar spray had a significant effect on all characters of vegetative growth. All spray treatments, i.e., Faster, Setter-2 and Faster + Setter-2, significantly increased plant fresh weight, plant height and number of branches per plant in the second season. Bronco cv. Surpassed cv. Paulista in plant yield, early yield and total yield. All spray treatments, i.e., faster, faster + Setter-2 and Setter-2 led to a significant increment in plant yield and total yield in first season as well as early yield in second seasons.
