Time series secondary data on area, production, productivity of cassava and other principal
crops in Ibadan Metropolis were arranged into 3 groups P1 (1980-81 to 1994-95), P2(1995-
96 to 2009-10) and P3(1980-81 to 2009-10) respectively based on farm sizes. 150 households
comprise 50 each from small, medium and large farm, spread over the three areas namely:
ajibode, eleyele and ijokodo were conducted using pre-tested interview-schedule and pertain
to the agricultural year 2010-11. Absolute relative changes, compound growth rate,
component analysis, techniques were employed to analyze the collected data. Area,
production and productivity of cassava and wheat increased during period P1and overall
period P3 but decreased in their second period P2. Area of cassava, wheat and sorghum
decline during second period but due to increase in productivity, production increases. The
production of cassava and yam shows negative growth in production and this was mainly
attributed to higher decline in acreage of the crops despite of positive and significant growth
in productivity. The component analysis revealed that yield contribution (55 to 86 per cent)
was higher in change of cassava, wheat and maize production while area contribution was
significantly higher in other selected crops.
