Two field experiments were carried out during two early summer seasons of 2012 and 2013 years at the Experimental Farm of Kaha Station, Qalubia Governorate to study the response of snap bean plants Poulista c.v to some agricultural treatments for early green pods yield production using (flowering, amcotone, super phosphate solution compounds) as foliar nutrition, (charcoal, agriculture sulphur and charcoal + agriculture sulphur) as soil addition and( Pea, onion and broad bean) as protection plants, in addition using black polyethylene plastic as a soil mulch. The results indicated that spraying the plants with flowering and amcotone compounds followed by super phosphate solution had the highest values of fresh and dry plant weight. While adding charcoal to the soil before sowing snap bean seeds gave the highest values of no. of leaves/ plant followed by spraying with flowering and amcotone compounds, respectively. The data showed also that spraying the plants with flowering, amcotone compounds, super phosphate solution, adding charcoal + sulphur and soil mulch with black polyethylene plastic exerted the highest values on all parameter of green pods its and yield attributes in both growing seasons. Concerning total sugars in dry pods it's clear that using protection plants with broad bean followed by onion were the best treatments on it. Generally it can recommend using any one of the mentioned treatments in this experiment especially flowering, amcotone compounds, super phosphate solution, charcoal + sulphur, respectively to obtain high green pod yield either early or total with the best quality. INTRODUCTION Snap bean plants (Phaseolus vulgaris L.) are considered one of an important vegetable crops cultivated in Egypt for local market and exportation. It is known that, bean plants are relatively sensitive to environmental stresses specially high and low temperature, that may occur in the field which negatively affect its growth, yield and even the quality of pods . The optimum temperature range for optimum bean growth or pod yield is between 16300C (Nonnecke, ( 1989 .In addition, temperature below or above this range had deleterious effects on plant performance as well as green pod yield. Seeds germination perhaps failing or might be delaying at temperature below 10°C as found by Poincelot ( 1980 ) . Many investigators indicated that bean plants are very sensitive to different environmental stresses such as chilling (El-Tohamy et al 2001, Singer et al 1996 ) drought (Millar and Gardner, 1972; Halterlein, 1983; ElTohamy et al 1999 ) and heat stress Dale, (1964). Hence, improving tolerance of bean plants to the possible environmental stresses by using different treatments is important to enhance its growth, maximize the yield and its quality. Flowering and Amcotone compounds contain Naphthyl acetic acid (NAA) and Naphthyl acetamide it is known that, NAA could activate membrane Ca2+-ATP as activate better movement of Ca. Banuelos et al (1988) reported that transport of calcium in tomato fruit is concerned with the basipetal transport of auxins. Moreover, NAA has also played main role in transport of Ca in Chinese cabbage (Wen et al 1991). Dong et al (2005) also suggested that spraying CaCl2 in combination with NAA to tomato plants for better Ca mobilization. Higher level of CaCl2 (1%) with NAA (0.02%) increased plant growth and yield by improving mineral uptake of tomato plants. Suty (1984) showed that, foliar application on faba bean plants with
