Undersowing sorghum with stylo as a means of improving fodder quality for dry-season grazing of livestock in the subhumid zone of Nigeria was investigated. Planting either Stylosanthes guianeusis cv 'Cook' or S. hamata cv 'Verano' simultaneously with local or improved varieties of sorghum reduced...
