O revolvimento do solo pode ser efetuado somente nas linhas de semeadura (semeadura direta) ou totalmente na área destinada à semeadura (preparo convencional), com arações, gradagens, subsolagem e escarificação (cultivo reduzido). A velocidade de deslocamento ideal para a semeadura é aquela em que o sulco é aberto e fechado sem remover exageradamente o solo, permitindo a distribuição das sementes em espaçamentos e profundidades constantes. O experimento foi instalado e conduzido em condições de campo, em solo classificado como Nitossolo Vermelho Distroférrico, na Fazenda Experimental Lageado da Faculdade de Ciências Agronômicas da UNESP, Campus de Botucatu. A presente pesquisa teve como objetivo avaliar a resposta da cultura do sorgo em quatro velocidades de deslocamento (3, 5 ,6 e 9 km h-1) e quatro sistemas de manejo de solo: SD (semeadura direta); GP (gradagem pesada + semeadura); GPL (gradagem pesada + duas gradagens leves + semeadura) e CR (escarificação + semeadura). Os dados obtidos foram submetidos a análise de variância em esquema fatorial 4 x 4 e um delineamento em blocos ao acaso com parcelas subdivididas. Foram determinados os seguintes parâmetros: massa seca da cobertura vegetal, porcentagem de cobertura do solo, resistência do solo à penetração, profundidade de deposição de sementes, área de solo mobilizada e profundidade de sulco de semeadura, velocidade média, patinagem do trator em operação, força média de tração na barra, potência média na barra de tração, capacidade de campo teórica do conjunto trator-equipamento, consumos horário e operacional... / Sorghum silage can be cultivated in dry and hot areas and environmental situations, in which productivity of some other forage is anti economic. Soil mobilization can be used only in seeding lines (no-tillage), or totally in the area for the seeding (conventional tillage), with plowing and drainage and sub soiling and chiseling (reduced crop). The ideal speed displacement for seeding is the one in which the rill is open and closed without exaggeratedly removing the soil, allowing seed distribution at constant spacing and depths. The experiment was installed and conducted in field conditions, in dystrophic Red Nitossol, at Fazenda Experimental Lageado, in Forest Sciences, College of Agronomic Sciences, São Paulo State University-FCA/UNESP-Botucatu (SP). The present research aimed at evaluating the response of sorghum crop in function of 4 displacement speeds (3, 5, 6 e 9 km h-1) and 4 soil management systems: SD (No-tillage), GP (Heavy disk harrow + sowing), GPL (heavy disk harrow + two leveling harrows + sowing) and CR (chiseling + sowing). The obtained parameters were analyzed statistically through analysis of the median values in a 4 x 4 factorial scheme and a completely randomized block design with split-plots. The following parameters were determined: dry mass of cover crop, percentage of soil cover, soil resistance to penetration, seed deposition depths, area of displaced soil, sowing depths, mean flow velocity, tractor slip in operation, median power of traction in the bar, median drawbar pull, theoretical field capacity of the group tractor-equipment, hourly and operational fuel consumption, early and final plant population, plant heights, stem diameter, fresh and dry mass of the aerial part, thousand grain mass, fresh and dry mass productivity. Speed variation in the operation... (Complete abstract click electronic access below)

No. of bitstreams: 1 DissertacaoLincolnGerke.pdf: 1910648 bytes, checksum: 6358009ffae74f406d3f40ede319052c (MD5) Previous issue date: 2015-02-27 / The sorghum was investigated as a food source to replace corn and alternative to sugar cane for ethanol production. Experimental in the State University of Paraná- UNIOESTE West station in Rondon-PR, with the hybrid ADV 2010, which was ensiled and processed with the same equipment already used in the processing of corn and sugarcane, produced a quantity of biomass that exceeded the volume of 165,000 kg of fresh weight per hectare in two sections with an ethanol production of 1,035 liters per hectare in the 1st section and 695 liters per hectare in regrowth, resulting in a cost of R$ 1.26 per liter produced in a rural property. The chemical composition of silage dry matter, acid detergent fiber, neutral detergent fiber, ash and crude protein were relevant in the silage. The results showed that there is viability in producing ethanol from sweet sorghum in rural properties, an additional investment. The economic potential of the material, addition of ethanol and silage extends to the biomass, which can be used for other purposes, and food, can be dried and incorporated into animal feed (fiber) in digesters supply or production steam boilers. / O sorgo sacarino foi investigado como fonte de alimento em substituição ao milho e alternativa à cana de açúcar para a produção de etanol. Na Estação Experimental da Universidade Estadual do Oeste do Paraná-UNIOESTE em Marechal Cândido Rondon-PR, com o híbrido ADV 2010, que foi ensilado e processado com os mesmos equipamentos já usados no processamento de milho e cana, produziu uma quantidade de biomassa que superou o volume de 165.000 kg de massa fresca por hectare em dois cortes, com uma produção de etanol de 1.035 litros por hectare no 1º corte e de 695 litros por hectare no rebrote, resultando num custo de R$ 1,26 por litro produzido em uma propriedade rural. A composição bromatológica da silagem em matéria seca, fibra em detergente ácido, fibra em detergente neutro, matéria mineral e proteína bruta mostraram-se relevantes nas silagens. Os resultados mostraram que há viabilidade em produzir etanol a partir do sorgo sacarino em propriedades rurais, mediante um investimento adicional. O potencial econômico do material, além da produção de etanol e silagem, se estende à biomassa, que pode ser usada para outros fins, além de alimentação, também pode ser secado e incorporado à rações (fibras), em alimentação de biodigestores ou produção de vapor em caldeiras.
