Two levels of CM substitution (25 and 50 percent) for industrial concentrate were studied; 3 treatments (with broiler chicks randomly assigned to blocks) during fattening were compared with a check treatment (100 percent industrial concentrate). Slaughter wt. over 1.5 kg/animal were obtained, wit...

A technique to study mycorrhizal effects on growth and P-uptake of cassava (Manihot escultenta, Crantz) grown in flowing solution culture is described. Phosphorus concentrations were carefully maintained constant at 0.1, 1, 10 and 100 ?M by daily analyses and adjustment of the nutrient solutions....
