Gce Model Questions Vol1 2024 Agricultural Science Question 20
Practice objective / multiple choice question 20 from the 2024 Gce Model Questions Vol1 Agricultural Science examination.
An extension officer wants to promote a new drought‑resistant maize variety to a community of 200 farmers. Adoption follows Rogers' logistic diffusion model \(A(t)=\frac{K}{1+e^{-b(t-t_{0})}}\) where \(K=200\) (maximum adopters), \(b=0.4\) yr⁻¹ and \(t_{0}=3\) yr. The officer can run demonstration plots; each plot reduces \(t_{0}\) by 0.2 yr and increases \(b\) by 0.02 yr⁻¹. If five plots are established, what is the expected number of adopters after 5 years with and without the demonstrations? Which strategy yields the higher adoption after 5 years?
