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 ...

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...

This paper ilustrates the principle determining cropping systems for Vertisols by reviewing work in the highlands of Ethiopia. The types of cropping systems that can be applicable in the different Vertisol environments are briefly described. These cropping systems include single cropping; multipl...

Weeds by definition are plants that grow in the wrong place. When their seeds or other plant parts are transported to other regions where their natural enemies are absent, they can multiply unhindered.
