THE BURNING OF CANE FIELDS AND THEIR INFLUENCE ON THE COMPOSITION OF WEEDS, IN AREAS OF THE ECUADORIAN COAST

Abstract

In many countries, the technology of burning the cane persists in large percentage before harvesting. There are ethical, technical, economic, environmental and social criteria, which justify the use of the green harvest, rather than burned, in sugar cane, without affecting productivity and cost structure. To verify this, a sampling of relative and absolute coverages by arvense species was carried out at 15, 30 and 210 days after harvest, grouping them by their differences in phenological and control characteristics in monocotyyledons, dicotyledons and cyperaceae. The results led to a simplification of the control work required in the glen harvested in green, because waste coverage reduces and delays the appearance of arvenses and transforms their composition, observing that in the first 30 days after harvest, monocotiledons virtually disappear and the relative coverage of dicotyledons in the green harvested cane increases to more than 68% in reverse of what happens in burned harvests. this work compares the results obtained in the quantity and diversity of arvenses arising after the harvest of sugar cane in the burnt and green variants.

Keywords: Harvest, burn, sugar cane.
