Interactions between soybean and weeds in a replacement series system, considering the effects of water stress Planta Daninha
Vivian,R.; Dourado-Neto,D.; Filho,R.V.; Silva,A.A.; Franco,R.B.; Correa,S.T.R..
Due to the increase of water deficiency in many farm regions and its meaning on weed interference, competitive interactions between soybean and three weeds were evaluated under water stress (20 to 40 days after transplanting) and no stress conditions. Three independent experiments were carried out in a growth chamber, being each one composed by the weeds Alternanthera tenella, Tridax procumbens or Digitaria ciliaris, along with the crop, in which soil water condition and plant composition effects were evaluated while in competition. A replacement series system was used, including both monoculture of each species and a mixture with a ratio of 50% between weed and soybean. A completely randomized design was used in factorial arrangement, with treatments...
