MANEJO DA ADUBAÇÃO ORGÂNICA DA CANA DE AÇÚCAR (Saccarum officinarum L.).

Abstract

Sugar cane in Brazil has been exploited for several centuries by the great masters of mills and landowners, predators and weeds were controlled by using excessive chemical sprays, thus polluting the soil, exhuming the macro and environmental microfauna, polluting rivers and local streams. This work aims to provide an organic cultivation of sugarcane (Saccarum officinarum L.), located in the community of Sitio Santo Antonio Granja to 6 km of the city of Areia, Paraíba in Paraíba Brejo region, this site an experimental planting was conducted of sugarcane as an agro-ecological system. an evaluation of the fertilization of manure and organic compound with the combination of (gray, manure and plant waste) was carried out; both fertilizations were acquired in the region, and the use of alternative methods of insect control predators agroecological system and identification of weeds. The design to be used will be a randomized block design with three replications. Plant height was measured every month, this measurement was performed with the aid tape measure to measure the length, and a caliper for the stalk diameter. The productivity will be analyzed according to the amount of sugar produced per kg ha-1, since the stalk samples are weighed. The project had a duration of one year. It also evaluated the rainfall to the rainy season and dry season. Finally this project had as its main aim to show that it is possible to produce sugar cane without the use of chemical fertilizers and drugs, thereby preserving the existing fauna in the planting soil, preserving the local waters, and also economically viable for family farms, finally making a sustainable production.
