Despite the advantages of root crops as important staple food crops in the tropics, research and development of such crops has been neglected. There is, therefore, the need for production, processing and utilization techniques to be developed, evaluated and made available to farmers. However, bec...

The widely recognized role of roots, tubers and bananas (RT&Bs) in achieving food security and providing income opportunities in the world’s poorest regions will be challenged by socioeconomic and climate related drivers. These will affect demand and production patterns and increase pressure on f...

Controlled pollination in root and tuber crops is challenging. Complex ploidy, cross-incompatibility, erratic flowering patterns, outcrossing, etc., limit the efficiency of breeding progress in these crops. Half-sib breeding that involves random pollination among parents is a viable method to har...

Response of cassava (Manihot esculenta Crantz) to fertigation as a form of nutrient delivery is unknown. The objectives of this study were to establish a balanced nutrition and to enhance agronomic nutrient use efficiency (ANUE) of cassava under fertigation. This study was conducted in the greenh...
