In: Egyptian journal of soil science 2003 v .43 (4)Summary: A field experiment was conducted at the farm of the National Research Center, QuaIubia Governerate, Egypt to study the application effects of different mixture of organic composts on the yield and uptake of some macronutrients by cowpea plants. Wastes of potatoes, banana and hyacinth plants and chicken were composted and added at the rate of 10 tons/feddan in different combination ratios (] :3, 1: I and 3: 1) in addition to 50 % of recommend chemical fertilizer dose. Yield of cowpea was significantly increased as a result of dl ffere11l treatments application as compared with the control. viI'. 100 % chemical fertilizer recommended dose. Application of different compost treatments significa11lly increased the uptake of N, P, K, Ca and Mg as compared to control treatment. The maximum increase of cowpea grain yields over control was recorded under the treatment of potatoes + chicken (I 02'Yr-) and the lowest was by potatoes + banana (74%). Generally, the positive effect of these treatments on yield and uptake of the macronutrients decreased in the following order: potatoes + chicken > potatoes + hyacinth> potatoes + banana.
