In 2012 the cost of growing a ...

The crown of a woody plant (tree, shrub, liana) is the branches, leaves, and reproductive structures extending from the trunk or main stems. Shapes of crowns are highly variable. The major types for trees are the excurrent branching habit resulting in conoid shapes and decurrent (deliquescent) branching habit, resulting in round shapes.
The main crop the Bine grow is the taro root, although they grow about 15 subsidiary crops including: sweet potato, banana, manioc, maize, yam, pawpaw, sugar cane, pineapple, and others. [11] The swiddens which can be placed in either savannas or forests are created by cutting down all the vegetation in the area that the swidden will be.
