摘      要：The use of organic manures, constitute an alternative to that of polluting artificial fertilizers. In this study, the effect of various levels of hen droppings fertilization on the production of biomass, chemical composition and carrying capacity of P. clandestinumwere evaluated at the Research and Experimental Farm (REF) and at the Animal Nutrition and Feeding Laboratory of the University of Dschang, between April and September 2016. A completely randomized block design comparing three nitrogen level of fertilization in hen droppings form (0;100 and 200 kg N/ha) on 4 m2 plot of P. clandestinum were used. Each treatment was carried out in four replications for a total of 12 experimental plots. Then a sample of 500 g of forage has been collected in the center of each plot, then dried and used for the evaluation of the biomass and the chemical composition of P. clandestinum, according to the level of fertilization and
