Yam was intercropped with maize, okra, and sweet potato and subjected to various periods of weed interference and weed-free regimes. The field trials were conducted for two cropping seasons at the research farm of the National Root Crops Institute, Umudike, Nigeria, 5° 29' N latitude and 7° 32' E...

Intercropping cassava (Manihot esculenta Crantz) and maize (Zea mays L.) can alleviate weed problems. The weeds which might otherwise build up before cassava covers the ground can be replaced by the cereal. The objective of this study was to determine effects of intercropping and fertilizer appli...

Maize dominated cassava irrespective of cassava or maize growth habit and the optimum maize population giving the highest production based on relative yield total or land equivalent ratio varied with maize variety in a tropical Alfisol at Ibadan, transition humid/subhumid zone in West Africa. The...

The relative changes in the composition of six cultivars of white yam (Dioscorea rotundata Poir) were investigated in three major yam ecozones in southeastern Nigeria. The component parameters measured were crude protein, starch and total soluble sugar of the six cultivars at maturity. Each of th...

On-farm research is aimed at developing technologies well match the goals and environment of farmers. At its various stages of diagnosis, choice of techniques, testing and validating technologies, ones would always ask questions: what technologies are developed, for whom and how? In this paper me...
This paper reviews intercropping research for a particular case: cassava-based crop combinations. Cassava is dominated in combination with maize while it is the dominating species in combination with low-growing species. Combinations with maize or legumes show a real biological advantage over the...
A two year trial was conducted a11badan to determine the effects of okra and melon on the soil moisture and leaf water status of cassava/maize intercrops. Inclusion of melon into a cassava/maize mixture. Especially where the cassava had sparse canopy, appeared to be an effective means of conservi...

A field experiment was conducted on a Paleustalf to examine the effect of fertilizer application and the possible yield limiting factors in a cassava-maize intercropping system. Application of N-fertilizer significantly increased maize grain and cassava root yields as well as N, P and K concentra...
