Resumen en inglés

Currently it is important to find alternatives that allow us to develop a more profitable and environmentally sustainable agriculture, leaving aside agrochemicals, which can cause irreversible damage to ecosystems, in nature plants are prone to biotic and abiotic factors which considerably affect their yields. Crops are frequently affected by the appearance of weeds, which can cause great losses. The presence of weeds will have a negative effect on the crop as they will be competing for water, light and nutrients. The department of Córdoba has a wide flora of weeds due to the edaphoclimatic conditions that are present, likewise a great diversity of crops of agronomic importance such as corn, cotton, rice, banana and vegetables are developed, it is believed that many of these weeds and crops develop allelopathic substances that have the ability to directly or indirectly inhibit the germination phases, growth and reproduction of other plants. In this sense, the objective of this research is to carry out a systematic review of information on the effects of allelopathy and its use for weed control in agricultural crops of agronomic importance in the department of Córdoba. The results obtained in the research showed that the phenomenon known as allelopathy can be a great alternative for weed control in agroecosystems, since many plants with allelopathic potential are currently known, which will allow us to have a more sustainable agriculture with the environment.
