Abstract
Two field experiments were conducted at the private field in El-Zarka City, Damietta Governorate, Egypt, during 2016 and 2017 seasons to evaluate the effects of organic fertilization rates (compost rates) and foliar spraying by some biostimulant substances on yield and its components,growth as well as quality of snap bean (Contender cultivar). A split-plot with three replicates was the experimental design. The vertical-plots to three compost rates i.e. without compost (control treatment), 50 % of the recommended dose (2 tons compost/fed) and 100 % of the recommended dose (4 tons compost/fed).The horizontal plots were devoted to four treatments of foliar spraying with some biostimulant substances i.e. foliar spraying with brassinolid at the rate of 10 ppm, moringa extract at the rate of 200 ppm, chitosan at the rate of 200 ppm and tap water (control treatment). The most important results can be summarized as follows: The highest values of vegetative growth characters, pod yield and its components as well as quality of snap bean pods were resulted from fertilizing with (4 tons compost/fed) 100 % .On the contrary, the lowest values of growth characters, pod yield and its components and chemical composition of snap bean pods were obtained from plants not treated with compost (control treatment). Foliar spraying snap bean plants three times with 200 ppm chitosan exceeded all foliar spraying with some biostimulant substances and resulted the highest values of vegetative growth characters, pod yield and its components as well as quality of snap bean pods. Followed by foliar spraying with brassinolid at the rate of 10 ppm and then moringa extract at the rate of 200 ppm. Whereas, the lowest values of vegetative growth characters, pod yield and its components as well as quality of snap bean pods were resulted with control treatment (spraying with tap water).It can be concluded that organic fertilizing with 4 tons compost/fed and foliar spraying three times with chitosan at the rate of 200 ppm folloued by spraying with brassinolid 10 ppm in order to obtain high yield and its components,growth as well as quality of snap bean (Contender cultivar).
