Rainfall variability and rubber production in Nigeria

Effect of Climatic Variability on Maize Production in Nigeria

The study examines the changes in climatic elements and agronomic parameter (maize hectarage and output) for maize production in different ecological zones of Nigeria from 1980 2002. The study also evaluated the degree of variability in these parameters. To achieve these objectives, secondary data on climatic elements and agronomic parameters for 22years were analysed using two – way Analysis o...

Rubber production in guayule: determination of rubber producing potential.

Optimum conditions for the rapid, efficient, nondestructive determination of rubber producing potential in guayule (Parthenium argentatum) were established. The rubber producing potential may be defined as the ability of the plant material to synthesize rubber from a precursor under specified conditions. To achieve this, stem slices taken from the first 5 centimeters of branches were incubated ...

Climate indices, rainfall onset and retreat, and malaria in Nigeria.

BACKGROUND & OBJECTIVES Rainfall in western sub-Saharan Africa is related to seasonal shifts of the Inter-tropical Convergence Zone, which moves northward early in the year, retreating in the second half of the year. The objective of the present study was to determine significant relationships between onset and retreat timing and climate indices. The relationship between timing and malaria case...

Labour Migration and Rural Agricultural Production in Southwestern Nigeria

In recent years, Nigeria witnessed significant labour migration coupled with reduction in rural agricultural productivity. Youths abandoned farms for ventures with high returns and less drudgery in cities thus labour availability in peak agricultural seasons became scarce. The declining farm population constituting mostly women and old men are not capable of producing sufficient food for the no...
