Three field experiments were carried out during summer seasons of 2005 and 2006 for second and third experiments, and autumn seasons of 2005/2006 and 2006/2007 for first experiment at Experimental Farm, Hort. Res. Station, El-Kassasien, Ismalia Governorate, Egypt, to study the effect of foliar spray of snap bean plants (Bronco cv.) grown in sandy soil, with Ca, Mg, Zn, Mn, Fe, vit. B1 and vit. C on growth, yield, pod quality and storability under cold storage condition of snap bean pods.First Experiment: Effect of Ca, Mg and vit. B1 on growth, yield and storability of snap bean cv Bronco grown in sandy soil.This experiment included four treatments; i.e., control (check), Ca at 0.5 % , Mg at 0.2 % and vit B1 at 25 ppm. The obtained results could be summarized as follows:1- Spraying snap bean plants grown in sandy soil during autumn season with Ca at 0.5%, Mg at 0.2% or vit B1at 25 ppm significantly increased number of both branches and pods/ plant in the two seasons compared to control. While vit B1 gave the highest values in this respect, followed by Ca at 0.5% and Mg at 0.2%, respectively in both growing seasons. Plant height did not affect by the above mentioned treatments.2- Foliar spray with Ca at 0.5 %, Mg at 0.2% and vit. B 1 at 25 ppm were the best treatments for enhancing dry weight of shoots and total dry weight/plant in both seasons compared to control treatment. Application of vit B1 at 25 ppm recorded the maximum values of total dry weight/plant, followed by Mg at 0.2%, then Ca at 0.5 %, respectively. The increases in the total dry weight/ plant were about 24.41 and 20.97 % for Ca at 0.5 %,
