- Descripción
- Field experiments were carried out in 1999 and 2000 to investigate the effects of conventional (CT) and no-tillage (NT) systems, interacting with three herbicide dose levels and three nitrogen (N) levels on weed growth and wheat production of two varieties. There was a higher grain yield for NT system compared with CT in one year. CT weed biomass was lower than from NT weed biomass, in both varieties. No differences on wheat biomass and grain yield were observed between full and reduced herbicide rates. N fertilizer increased wheat biomass and grain yield significantly. Only N medium level had an effect upon weed biomass with respect to non-fertilized plots, while the highest fertilization rate lowered weed biomass. Conventional tillage, reduced herbicide rates and nitrogen fertilization were effective ways of limiting weed production in wheat.
Experimentos foram conduzidos sob condições de campo em 1999 e 2000 a fim de investigar os efeitos dos plantios convencional (PC) e direto (PD), em combinação com três doses de herbicidas e três de nitrogênio (N), no crescimento de plantas daninhas e produção de duas variedades de trigo. Foi observada produção maior de grãos PD, comparado ao PC, durante um ano. A biomassa das plantas daninhas no PC foi menor do que no PD, para as duas variedades. Nenhuma diferença em biomassa e produção de grãos de trigo foi observada entre as doses de herbicida integral e reduzida. N aumentou a biomassa do trigo e produção de grãos significativamente. Apenas o nível médio de N teve efeito sobre a biomassa das plantas daninhas em relação à não-aplicação de N, enquanto uma taxa maior de N diminuiu a biomassa das plantas daninhas. No plantio convencional, doses reduzidas de herbicida e aplicação de N foram efetivos na limitação do crescimento das plantas daninhas no cultivo de trigo.
