Title A name given to the resource Controle de plantas daninhas em cultivos orgânicos de soja por meio de descarga elétrica Weed control in organic soybean using electrical discharge Creator An entity primarily responsible for making the resource Alexandre Magno Brighenti, Deodoro Magno Brighenti Description An account of the resource Dois experimentos foram instalados em semeadura direta, em área de cultivo orgânico de soja, no município de São Miguel do Iguaçu, Paraná (PR), com o objetivo de avaliar o controle de plantas daninhas na cultura da soja (BRS 232) por meio de descarga elétrica. O delineamento experimental foi blocos casualizados, com quatro repetições. No experimento 1, fixou-se a voltagem de 4400V e, no experimento 2, de 6800V. Em ambos os experimentos, os tratamentos consistiram das variações de rotação do motor do trator (i) 2200rpm (rotações por minutos); (ii) 2000rpm; (iii) 1600rpm e as testemunhas (iv) capinada e (v) sem capina. O equipamento utilizado para aplicação dos tratamentos foi o Eletroherb (Sayyou do Brasil). As plantas daninhas existentes na área experimental foram o amendoim-bravo (Euphorbia heterophylla), a corda-de-viola (Ipomoea spp.), a guanxuma (Sida spp.), o capim-marmelada (Brachiaria plantaginea) e o capim-colchão (Digitaria spp.). O emprego de descarga elétrica é eficiente no controle das plantas daninhas da cultura da soja. A rotação 2200rpm proporcionou o melhor controle e, consequentemente, a maior produtividade da soja.Two experiments were carried out in no-till organic soybean area in São Miguel do Iguaçu, Paraná State, Brazil, in order to evaluate the weed control using electrical discharge. The experiments were arranged in a complete block design, with four replicates. The voltages were fixed in 4400V (experiment 1) and 6800V (experiment 2). In both experiments, the treatments consisted by different revolution tractor: (i) 2200rpm (revolutions per minute); (ii) 2000rpm; (iii) 1600rpm; and two checks [(iv) unweeded control and (v) weeded control]. The equipment Eletroherb (Sayyou do Brasil) was used to apply the electrical discharges. The weeds presented in the experimental area were wild poinsettia (Euphorbia heterophylla), morningglory (Ipomoea spp.), prickly Sida (Sida spp.), alexandergrass (Brachiaria plantaginea) and crabgrass (Digitaria spp.). The electrical discharge use was efficient in controlling weeds in soybean crop; 2200rpm produced efficient weed control and, consequently high soybean yield.
