Resumo: | A long term experiment with sugar cane (RB 739735) was installed at Linhares, Esp?rito Santo State, in order to evaluate the technical and edaphic aspects of two systems of sugar cane harvesting: the first with previous burning of the sugar cane (Burned Cane) and the second with spreading of straw on soil surface (Green Cane). The experiment was installed on a Yellow Podzolic soil and the experimental design was completely randomized with six repetitions. After six years of cropping, a process of soil degradation was observed in the Burned Cane system, with decreasing of aggregate mean diameter and increase of soil bulk density at 0-5 cm deth. Differences of total porosity and poros distribution as a consequence of harvesting system were not detected. The soil water infiltration was greater in the areas under Green Cane harvesting system, but the same results were not observed when the saturated hydraulic conductivity was measured using the method of the steady state permeameters. The earthworm population (Megascolicidae), annual balance, was significantly greatest at the Green Cane system. However, there were no differences between earthworm population in the differents periods of the year. There were no differences in the quality of sugar s cane juice and stem, for the periods of days after harvesting. The harvest efficiency in the Green Cane system was equivalent, in average, to 40% of the Burned Cane. The time necessary to control the weeds at the Green Cane system was 80% lower than in the Burned Cane system. On the other hand, this economy was equivalent to the cost of spreading of straw on the soil surface. The additional volume of undesirable material, in the transportation container, for the Green Cane system, was equivalent to 4,6 ton/ha, consequently diminishing the load density during the transport. The study of cost and lucrativity points out that the improving of harvesting efficiency, in addition to a possible greater productivity of Green Cane system, are the main aim to be acquired in order to make Green Cane system a more attractive business option to farmers. |

O experimento foi instalado em um solo Podz?lico Amarelo. O delineamento utilizado foi o inteiramente casualizado com 6 repeti??es. Ap?s seis anos de cultivo, constatou-se um processo de degrada??o do solo no sistema de manejo Cana Queimada, evidenciado pela diminui??o do di?metro m?dio ponderado dos agregados est?veis e aumento da densidade do solo na profundidade de 0-5 cm. N?o foi detectado altera??es significativas na porosidade total e distribui??o de poros devido ?s pr?ticas de manejo do sistema de colheita. Verificou-se ainda que a velocidade de infiltra??o instant?nea foi maior nas ?reas sob tratamento sem queima, sendo que os mesmos resultados n?o foram encontrados quando se avaliou o fluxo de ?gua saturado atrav?s do m?todo do condutiv?metro. A popula??o de minhocas (familia megascolicidae), balan?o anual, foi significativamente maior no tratamento Cana Crua. Entretanto, n?o foi encontrada diferen?a entre a popula??o de minhocas nas diferentes ?pocas do ano. N?o houve diferen?a na qualidade da cana e do caldo, nos intervalos de dias ap?s o corte. A efici?ncia de corte do sistema Cana Crua foi equivalente, em m?dia, a 40% da obtida no sistema Cana Queimada. O tempo necess?rio para o controle de ervas daninhas no sistema de manejo Cana Crua foi 80% menor que no tratamento Cana Queimada. No entanto, esta economia praticamente se diluiu com o tempo adicional necess?rio ao espalhamento do palhi?o. O volume adicional de mat?ria estranha, para a variedade estudada, na carreta, no sistema Cana Crua, foi de 4,6 ton/ha, diminuindo a densidade de carga durante o transporte. O estudo de custo e lucratividade indica que o aperfei?oamento da efici?ncia de corte, associado ? poss?vel maior produtividade do sistema cana Crua ? a principal meta a ser alcan?ada no sentido de tornar este sistema economicamente mais atrativo para o produtor de a??car e ?lcool. xvMade available in DSpace on 2016-04-26T19:36:47Z (GMT).
