For instance, research has explored the benefits of growing target crops, such as soybean or cotton, on soil previously occupied by a cover crop. However, fewer studies have investigated the potential negative implications of NTSs. Since, certain cover crops can release exudates harmful to other plants, there is a need to fill this knowledge gap. To this end, this study used four experiments to investigate the effects of two species of <em>Urochloa</em> on cotton germination, plant emergence, and biomass production. In the first two experiments, cotton germination was evaluated by placing seeds on paper rolls moistened with different concentrations of root washings of <em>Urochloa</em> plants cultivated for 45 days in tubes kept in a greenhouse, and desiccated with or without glyphosate. In the other two experiments, the emergence and biomass production of cotton were evaluated, which was sown in pots where two species of <em>Urochloa</em> were previously grown and subsequently desiccated or not with glyphosate, and managed in three ways: a) the entire plant of <em>Urochloa </em>spp. was kept in the pot (shoots and roots in the soil), b) only the aerial parts of <em>Urochloa</em> spp. were kept on the soil surface, and c) only the roots of <em>Urochloa</em> spp. were kept in the soil. Cotton seed germination was negatively affected by <em>Urochloa </em>spp. root washings. Both the emergence percentage and emergence speed index of the cotton plants were negatively affected when only the leaves of <em>Urochloa</em> spp. were kept in the soil with and without glyphosate desiccation. No adverse effect of the treatments (pre-cultivation and management of <em>Urochloa</em> spp.) on the production of cotton shoot and root biomass was observed.</p>}, number={2}, journal={REVISTA DE AGRICULTURA NEOTROPICAL}, author={Asmus, Guilherme Lafourcade and Mendes Lamas, Fernando}, year={2023}, month={Mar.}, pages={e7298} }
