The IBSNAT (Internal Benchmark Sites Network for Agrotechnology Transfer) CERES-Maize model, which stimulates a sole crop of maize, was tested during the 1990 and 1991 growing seasons at Ibadan in southwestern Nigeria. The maize model is designed to simulate plant physiological processes (nutrien...

A researcher-managed on-farm experiment was conducted on a soil with low 1.90 mg/kg available phosphorus (P) to evaluate nutrient carryover from soybean grown under different P management options and productivity of maize grown in rotation. Promiscuously nodulating 110-day maturing soybean variet...

Population increases, land-use changes and marketing opportunities are important factors affecting crop-livestock integra- tion particularly with respect to their effect on soil fertility and feed supply for ruminant livestock. As the human population density rises, crop farmers and grazers are f...

Long time series of daily meteorological data that are needed in various applications are not always available or appropriate for use at many locations. The Weather Generation Model (WGEN) developed by Richardson and Wright (1984) was evaluated as a substitute for daily observed data at 17 sites ...

Maize simulation models are proposed as tools for assessment of response to nitrogen (N) fertilizer and varieties in order to explore potential target zones for improved maize varieties. The CERES-maize model in the Decision Support System for Agrotechnology Transfer version 2.1 was tested using ...

Reports of changes in the seasonal and annual rainfall in Nigeria suggests that a more detailed analyses of the geographic extent of these changes and of their impact on agriculture could be of value. Variation in the growing season (April to September) rainfall from stations across Nigeria was a...

Two field experiments were conducted in a subhumid environment with tropically developed soyabeans to plant densities of 13.3-57.1 plants/m2. Grain yield, total dry matter GDM) and seeds/m2 were highest at 57.1 plants/mz. There was a linear relationship betweenT DM, seeds/m2a nd crop growth rate ...

Stratifying a broad target growing area of a crop into different ecological zones has been an important first step in plant breeding. To cater for the diverse maize growing environments in West and Central Africa, germplasm development and testing at IITA have been targeted to four agroecological...

Maize productivity relationships were studied at Ibadan in the derived savanna of south-western Nigeria using the CERES-Maize simulation model at six crop densities ranging from 2.96 to 13.3 plants m-2. The absolute growth rate for all plant components decreased linearly with density. The optimum...
