Banana (Musa) is one of the most important economic and staple crops in the world. The majority of edible cultivated banana species arises from two species of the Eumusa group, Musa acuminata (A genome) and Musa balbisiana(B genome). In order to assess the biochemical diversity that exists in our...

In Mushie ranch, 157 N`Dama progeny of four sires, 95 males and 62 females, were used to estimate the habitability levels for aspects of parasitaemia, anemia control, immune response and animal performance. The males were exposed to a high natural trypanosome challenge, and body weight, trypanoso...

Cyanide is toxic to most living beings. Cassava roots release cyanide in the human body if they are not properly processed before consumption. The environmental effects on the cyanogenic potential (0.1» and some cuIinary qualities of five divergent cassava clones were studied in two agro-ecologic...

There is strong relationship between the weight of stake to be planted and it ability to emerge. Therefore, only good quality stem should be cut, partitioned into stakes, and treated for planting to optimise the limited resource of land area and other input engaged in the cassava cultivation ente...

Production of improved water yam (Dioscorea alata) genotypes that are suitable for the preparation of amala (a popular darkish Nigerian food) would likely enhance the economic importance of the crop in Nigeria. Fermented flour (oven dried and sun dried) made from tubers of eight new improved D.al...

A field collection of 90 sweetpotato (lpomoea batatas) accession collected. from various sources within and outside Nigeria were characterized at the llTA High Rainfall Station in Onne, Rivers State between June and August 2006. The objective of the study was to identify their distinctive charact...
