Efecto de cultivos invernales sobre la dinámica del enmalezamiento invernal

Weeds are one of the main problems of the agricultutal system. Within the integrated control of weeds, one of the strategies is the use of weed suppressing crops, thus considering those crops that, due to their wrowth and development characteristics, or their allelopathic potential, are capable of reducing the proliferation of weeds. The objetive of this work is to study the effects of different winter crops on the biological processes (establishment, growth, development and reproduction) of weeding. The crops used were wheat, barley, rapessed and oats. In each evaluation the number of plants of each weed species and their stage of development were recorded. A significant variation in the dynamics of weeding as well as its biological processes could be observed between the different winter crops, attributed to the characteristics of each crop in conjunction with the management of herbicides, which suggests the importance of considering these aspects for effective control of weeds in winter crops.
