This experiment was carried out during the two successive winter seasons of 2009/2010 and 2010/ 2011 at clay loam soil in the farm of Faculty of Agriculture, Moshtohor, Benha University, Kalubia governorate, Egypt to investigate the effect of foliar spray by some natural growth stimulating compounds as hammer, alga 600, chitosan, peptone and phosphoric acid on vegetative growth and chemical composition of plant foliage as well as green pods yield and its components and dry seeds yield of pea plants cv. Master B. Such study aimed also to reduce the amounts of mineral fertilizers used and in turn decrease the pollution resulting from using mineral fertilizers by using growth stimulating compounds.
Treatments were arranged in complete randomized blocks design with four replicates. The results revealed that mentioned characters responded to the used foliar application of Hammer at 2g /liter, Alga 600 at 0.5 g/l, chitosan at 1%, peptone at 1g/l and phosphoric acid at 1 ml/l five times during the growing season starting 21 days after complete germination and every 7 days by intervals compared with the control treatment. In this concern alga 600 and peptone were superior compared to the other tested treatments.
