This work was carried out during the two seasons of 2008 and 2009 aiming to study the effect of cattle manure combined with biofertilizers (phosphorein and/or nitrobein) as well as their interactions treatments on the growth, sepals, seed yields and some chemical constituents of roselle plants. The obtained results show that all levels of cattle manure and inoculated biofertilizers and their interaction enhanced the vegetative growth parameters, sepals yield and seeds yield of roselle plants, as well as their quality. The interaction treatment of cattle manure (30 m3/fed.) combined with mixture of biofertilizers gave the best results of sepals yield, seed yield, the anthocyanin and vitamin C contents in sepals as well as the chemical constituents of leaves per plant (nitrogen, phosphorus, potassium, protein and total carbohydrates). The interactions treatments between cattle manure (30 m3/fed.) combined with biofertilizers alone or mixture gave the highest values of sepals yield, anthocyanin and vitamin C contents in the sepals of roselle as well as the chemical constituents of leaves per plant (nitrogen, phosphorus, potassium, protein and total carbohydrates).
