Independent of the kenaf cultivar selected, seed storage prior to planting but greater plant populations. It requires field where rain water doesn't get accumulated. From 2005 to 2011,the kenaf planting area expanded from 42.5 to 400 hectares (Anonymous 2011). Turrialba Crops (Abstr.). dispersal and that any cross-pollination is a consequence of insect activity.
