HANDUNG OF SUGARCANE TRASH. 1. EFFECTS ON INDUSTRIAUZED CULMS AND OTHER AGRONOMIC CHARACTERISTICS

[摘要] A field experiment was conducted at Federal University of Santa Maria, RS, Brazil, with objective to study different methods of handling sugarcane trash and its effects on productivity and other agronomic characteristics. It was tested five treatments of sugarcane trash, in four consecutive harvests. Treatments of burning the sugarcane plant before harvest, harvesting and burning the remaining trash and remove the trash from plots behaved the same way in relation to industrialized culms production. Aligning it in alternate rows and triturate and redistribute in the field showed less productivity. In relation to brix % juice, it could be suggest any one method of handling the trash studied, because all them presented brix % juice above 18%. The production of green matter from the upper immature part of the stalk, diameter, mean weight of the culm and internode number was not affected by methods of handling the trash.
