Resumo: | Forage sorghum can be grown in areas presenting dry and hot environmental situations where the yield of other grasses can often be uneconomical. The objective of this study was to analyze the operating performance of agricultural machines in the deployment of sorghum forage in four tillage systems, as follows: no-tillage system, disk harrow + seeding, disk harrow + two light disking + seeding, minimum tillage + seeding and four seeding different speeds, as follows: 3, 5, 6 and 9 km h-1. The study was performed under field conditions in FCA / UNESP, Botucatu County, SP, Brazil. The data were subjected to variance analysis in a simple factorial 4 x 4, and a random block design with split plots. Operational performance of the agricultural machinery, physical characteristics the soil, its water content and the yield of dry matter and green sorghum were determined. The operational performance of agricultural machines in the deployment of sorghum forage is influenced by the sowing speed and the soil tillage system used. Chisel plow was the equipment that required the highest mean traction force, mean traction and slip, as well as the lowest mean speed for the studied tillage system. Forage sorghum showed higher yields in no-tillage systems at a seeding speed of 5 km h-1. |

O objetivo do trabalho foi analisar o desempenho operacional de máquinas agrícolas na implantação da cultura do sorgo forrageiro em quatro sistemas de preparo do solo: semeadura direta; gradagem pesada + semeadura; gradagem pesada + duas gradagens leves + semeadura; cultivo reduzido + semeadura e quatro velocidades de semeadura: 3, 5, 6 e 9 km h-1. O experimento foi instalado em condições de campo, na FCA/UNESP, Campus de Botucatu - SP. Os dados obtidos foram submetidos à análise de variância em esquema fatorial simples, 4 x 4, sendo o delineamento experimental em blocos ao acaso com parcelas subdivididas. Foram estudados o desempenho operacional das máquinas agrícolas, as características físicas do solo, o teor de água e a produtividade de massa seca e verde do sorgo. Concluiu-se que o desempenho operacional de máquinas agrícolas na implantação da cultura do sorgo forrageiro é influenciado pela velocidade de semeadura e pelo sistema de preparo do solo. O escarificador foi o equipamento que exigiu do trator a maior força média de tração, potência média de tração, patinagem e apresentou a menor velocidade média de trabalho para os sistemas de preparo estudados. O sorgo forrageiro apresentou maiores produtividades no sistema de semeadura direta na velocidade de 5 km h-1.UEL2011-12-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtigo Científicoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/540610.5433/1679-0359.2011v32n4Sup1p1813Semina: Ciências Agrárias; Vol. 32 No. 4Sup1 (2011); 1813-1824Semina: Ciências Agrárias; v. 32 n. 4Sup1 (2011); 1813-18241679-03591676-546Xreponame:Semina.
