At Shika in a subhumid environment of Nigeria, a 3-year study was carried out to select newly developed groundnut varieties for use in crop--livestock production systems. The study examined 11 groundnut varieties. Emergence time, plant stands at full emergence, forage and seed yields and yield components were examined. Whole plant samples were analysed for crude protein (CP) content. Varieties ICGV 87123 gave the lowest forage yield and cultivar M517-80I, the highest, with seven varieties recording forage yields above 5 t/ha. The CP content of forage was lowest (14.8%) for variety M576-80I and highest (21.6%) for variety M554-76. Mean seed yield (over 3 years) varied significantly from 0.73 to 1.68 t/ha. Only two varieties had mean seed yield > 1 t/ha. The relationship between seed and forage yields was positive and significant (r = 0.529, P < 0.006). Varieties RMP 12, 88-80I and M517-80 were most promising for both forage and seed production. Reprinted by permission of the publisher.
