Report 1992

Autor: Fischer, Albert J. Ramírez Suárez, A.

Growth analysis and competition studies involving red rice and rice "Oryzica 1" were conducted at CIAT, Colombia, during 1989 and 1990. In competition red rice (2 biotypes) grew taller than Oryzica 1, but had similar leaf area. During the first 60 days after emergence (d.a.e.) Oryzica 1 tillered ...

Autor: Fischer, Albert J. Ramírez Suárez, A.

Weed control in Latin America is costly and heavily dependent upon herbicides. Often irrigated rice farmers spray herbicides in late post-emergence at 30 to 44 days after emergence (d.a.e.). The economic benefits from such late applications are often unclear. Two experimental approaches involving...
