To conduct the knowledge test, respondent is given one (1) mark for each correct answer and zero (0) mark for each wrong answer. Based on the response given by the farmers, 44 items were included in the knowledge test using Item Difficulty Index which ranges from 20 to 80, Discrimination index which ranges from 0.2 to 0.8 and Point Biserial Correlation. The reliability of the knowledge test was measured with the help of split half method and reliability coefficient r = 0.83 which implies that this knowledge test is reliable.
