Improved cropping systems with in-situ production of organic matter require the input of additional inorganic N to maintain crop production in a sustainable way. For proper management of this fertilizer-N, it is necessary to quantify how the applied fertilizer N is used by the various components ...

Standard stake yield (SSY) was estimated using data from multi-locational trials in 11 locations. These were: Onne, Obrikom, Warri, Obayantor, Umudike, Nanka, Akure, Ajibode, Ibadan, and Zaria during 2003-2005 season. The aim was to identify location suitable for stem production and also to estim...

A two year trial was conducted at the inland valley of the National Root Crop Research Institute, Umudike during the dry season of 2003/2004 and 2004/2005. The purpose was to evaluate the suitability of five hybrid yam clones of dry season yam production. The yams were planted in manually made ri...

Even though cassava is a durable crop, it has certain husbandry requirements and is responsive to favorable crop management practices. Healthy, fresh stem cuttings from mature cassava plants are the best planting materials. Depending on moisture conditions of the soil, farmers plant cassava cutti...

Factors affecting cowpea growth in millet/cowpea intercropping were investigated in northern Nigeria. Ecological studies showed that cowpea received from < 30% to > 75% of incident light inside the intercropped canopy. In these light-limited conditions, cowpea varieties with a spreading growth ha...

The contribution of root and leaf litter to soil nitrogen dynamics, nitrogen uptake and balance was evaluated under cereal–legume rotations in a tropical moist savanna soil. Two legumes, soyabean (Glycine max) and stylo (Stylosanthes hamata), and maize (Zea mays) as a control were grown in four f...
