Waec Model Questions Vol1 2023 Agricultural Science Question 43
Practice objective / multiple choice question 43 from the 2023 Waec Model Questions Vol1 Agricultural Science examination.
An agricultural extension programme uses a logistic model to describe the adoption of a new crop technology. The maximum possible adoption (carrying capacity) is 100 % of the target farmers. At the start of the programme (t = 0) only 10 % have adopted. The intrinsic adoption rate r (per year) is proportional to the number of training sessions held each year: r = 0.05 S, where S is the number of sessions. The programme has an annual budget of $2 000 and each training session costs $250. Determine (a) the maximum number of sessions that can be held each year, (b) the corresponding intrinsic rate r, and (c) the number of years required for adoption to reach 80 % of the target farmers.
