| Abstract | ||||
| Two field experiments were conducted during the two successive seasons of 2010/2011 and 2011/2012 at the Experimental Farm, Kaha station, Kalubia Governorate to study the effect of using four plant densities (5 cm,7.5 cm apart on one side of the irrigation line,10 and 15cm apart on two sides of the irrigation line) and five safety materials, i.e. amino more, yeast extract, oligo-x and salicylic acid in addition to the control as foliar spray on snap bean plants and the effect of that on vegetative growth, green pods yield and physical as well as chemical pod characters of cv. Poulista. The results indicated that, plant density 7.5 cm on one side of ridge (22plant/m2 ) and sprayed with yeast extract, amino more or oligo-x, respectively, gave the highest values of all measured vegetative growthparameters (plant length, number of branches and leaves/plant, fresh and dry weight of plant), pod number/plant and pod yield/plant except plant length and stem diameter in both growing seasons. Moreover, planting at5 cm on one side of ridge (33plant/m2 ) and sprayed with yeast extract in the first season and amino more in the second one were the best treatments for pod yield/fed. It is obvious that plant density15 cm on two sides of ridge and spraying plants with yeast extract, amino more or oligo-x, respectively increased the values of all chemical properties but didn’t reach to 5% level of significance except N%, protein% in the second season. Generally, it can be recommend by using plant density 5cm on one side (33plant/ m2) or 7.5 cm on one side (22plant/m2) and foliar spray by yeast extract, amino more followed by oligo-x to obtain the highest green pod yield with best quality. | ||||
