Variation in pod and seed yield among twelve cultivars of Bambara groundnut was investigated in 2004 and 2005 cropping seasons. The mean performance revealed that BG7004AS despite its recorded low number of pods per plant, had the highest 100 seed weight, pod width, pod length, seed width and seed length, followed by BG7002AS, BG7009BS and BG70010AS, which had the best yield and yield component...

A water simulation model (WaSim) to simulate the growth and development of Amaranthus cruentus as well as the components of water balance for a typical sandy-clay-loam soil of Akure has been described. Dry season experiments were carried between January and March of 2005 and 2006. Amaranthus seeds were established on the field and three irrigation water managements were imposed on the crop to d...
