Methodology
The study was carried out throughout the five agricultural zones in Nigeria. Agricultural researchers and extension personnel constituted the study population. Multistage random sampling was adopted to select the respondents. The first stage involved the use of proportionate random sampling technique to select three research stations in the South-West, two from Central and two from the North-West agricultural zones while the only research stations in each of South-East and North-East zones were selected. The second stage involved a random selection of 10% of the researchers at the selected stations giving 73 researchers. For the ADPs, 10% of the extension personnel in the 6 states, where the research stations have been selected were randomly selected, which gives 135 extension respondents. Structured questionnaire was used to collect information from the respondents according to the objectives of the study. Descriptive and inferential statistics such as frequencies and percentages were used to analyse the data collected, while binomial logit regression model and t-test were the inferential statistics used for the study. All tests were carried out at p=0.05.
