RESPONSE OF SNAP BEAN PLANTS TO SOME AGRICULTURAL TREATMENTS FOR EARLY YIELD PRODUCTION

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 addingcharcoal to the soil before sowing snap bean seeds gave the highest values of no. of leaves/ plant followed by spraying withflowering 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 byonion 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.
