| Abstract | ||||
| Two filed experiments were carried out at a private farm in Behaira Governorate, Egypt during 2012 and 2013 summer seasons. Experiments aimed to study the effect of two widely marketing (commercial safe compounds). First, is a seaweed extract (with commercial name of sea weed) at 1, 2 and 4 ml/l while the second is a mixture of free amino acids (with plant origin and commercially name is sway) at 2,4and 8 ml/l and seaweed at 2 ml/l + amino acids at 4 ml/. The two compounds were applied as foliar spray three times on common bean plant (Phaseolus vulgaris L.) starting at 25 days of plant age with 10 days intervals between each spray and others. The obtained results clearly indicate that different applied treatments increased estimated or measured growth characteristics i.e., plant height, stem diameter, number of branches and leaves/ plant, total leaf area /plant, dry weight of shoots and specific growth rate as well as paralley increase of photosynthetic pigments and total chlorophyll SPDS with increasing seaweed and amino acid sprayed levels at the age of 65 days after sowing during 2012 and 2013 seasons. As for the yield and yield components i.e., number of pods/plant, pod weight (g) , number of seeds per pod, number of fully seeds /plant, , weight of 100 seeds (g), number of seeds/ plant, seed yield (g) /plant and the harvest index. Also, biochemical constituents of N, P, K, Mg, Ca, Fe, Zn, Total carbohydrates and crude protein in leaves at 65 days of plant age were existed in the two assigned seasons. In addition, the most effective treatments was that of sea weed at 2 ml/l combined with the amino acids at 4 ml/l was the most effective treatment in this respect. | ||||
