Taungya system is an agricultural practice in which farmers grow food crops on forest land together with young forest trees. The farmers cultivate crops between the rows of newly planted trees until the trees become mature enough to form a canopy. After that, farming stops and the land is left for the forest plantation to continue growing.
(6aii)
(i) To reduce cost of forest plantation establishment.
(ii) To allow farmers grow food while protecting young trees.
(6b)

Given:
Total number of farmers = 100
Innovators = 25
Early adopters = 34
Never adopters = 14
Late adopters = Total number of farmers – (Innovators + Early adopters + Never adopters)
= 100 – (25 + 34 + 14)
= 100 – 73
= 27
Percentage of late adopters = (Number of late adopters / Total number of farmers) × 100
= (27 / 100) × 100
= 27%
