Improvement of manure quality and crop yields by cattle supplementation

摘要

Animal and crop productivity are limited by mineral deficiencies in the Sahel (Cissé et al.,1996 ) where millet ( Pennisetum glaucum) and groundnut ( Arachis hypogaea) are two major food and cash crops.Livestock are is also soil fertilizing agents by nutrient recycling from excretions ( Hiernaux and Rivera, 1996 ).A trial was conducted to assess the effects of application of the manure from cattle supplemented with rock phosphate and/or nitrogen on crop growth and yield in a pearl millet‐groundnut rotational system.
