Effects of density and sowing pattern on weed suppression and grain yield in three varieties of maize under high weed pressure
We tested the hypothesis that improved weed suppression
by maize can be achieved through increased crop
density and spatial uniformity. Field experiments on
three varieties of maize sown at three densities (5, 7
and ...
Effects of hand weeding strip and nitrogen fertilizer on corn plants
(2005-01-20)
The objective of the present research was to evaluate effects of different strip weed control associated with nitrogen fertilizer on corn applied after planting. The experiment was set and conducted in Botucatu, São Paulo ...

Interferência e estudos fitossociológicos da comunidade infestante na cultura do sorgo sacarino
(2017-01-01)
This research was carried out to evaluate the interference periods and phytosociological indexes of the weed community on sweet sorghum, hybrid CVSW 80007, cultivated for two seasons in a year. The treatments were based ...
Effect of soybean crop structure on large crabgrass (Digitaria sanguinalis) growth and seed dormancy
(Weed Science Society of America, 2021-05)
Crop-weed interactions are affected by environmental alterations resulting from a crop's presence, such as modifications in temperature, light quality and quantity, and moisture conditions that could modify weed performance. ...
Species richness and evenness as a function of biomass in arable plant communities
(Wiley Blackwell Publishing, Inc, 2011-06)
We evaluated the hypothesis that competitive dominants change the species richness and evenness of arable plant communities. Three field experiments including cool-season crops and unsown short fallows were carried out in ...
