One-eye-set sugarcane susceptibility to weed interference
(2018-10-01)
The new technology of sugarcane planting, known as one-eye-set seedlings, offer a high standard of plant health and vegetative vigor. However, there are no reports in the literature that evaluate the weed competition with ...
Interferência e estudo fitossociológico da comunidade infestante na cultura da beterraba transplantada
(2008-12-01)
The objective of this research was to study the phytosociological and critical interference periods of weed communities on transplanted beets. The treatments consisted of increasing weekly weedy/weed-free periods, starting ...
WEED INTERFERENCE PERIODS IN PRE-SPROUTED SUGARCANE SEEDLINGS
(Univ Federal Vicosa, 2019-01-01)
