Experiments were designed and implemented to evaluate fresh and dry forage yield, vegetative growth behaviour, and quality determinations of two indigenous-native legumes (Bonavista bean and Fodder cowpea) under six sources of promoting phosphorus treatments: Control, sulpher as a content, soil application of calcium super phosphate, sulpher+ calcium super phosphate, soil phosphoric acid, foliar phosphoric acid and phosphoric acid as soil+foliar application. Two field experiments were carried out at the Experimental Research station, Faculty of Agriculture, Moshtohor, Benha University, Kalubia Governorate during two summer growing seasons (2011 and 2012). Results could be concluded as follows:
Data clarified significant differences in total fresh and dry forage yield for each of Bonavista bean and Fodder cowpea types. Highest production of fresh and dry forage yield; Leaf:Stem ratio; plant height; CF% and P% contents were obtained for Whit B. bean. whereas, the highest values of number of shoots/m2 and CP% were recorded for Creamy Fodder cowpea type with significant differences of variable magnitudes.
Concerning promoting phosphorus source treatments: the highest values of the studied parameters were obtained for fresh forage yield from using Sulpher; dry yield, number of shoots/m2and CP% from using Sulpher+ Calcium super phosphate (1:1); CF% and P% from Calcium super phosphate; Leaf:Stem ratio from using Phosphoric acid as soil application and the tallest Plants from the control treatment, respectively with significant differences of various magnitudes.
