The intuition of the use of cover plants is to cover and protect the soil from erosion and degradation processes. In addition to soil cover, the straw deposited by the cover plants ensures nutrient cycling. Braquiaria (Brachiaria brizantha), Crotalaria (Crotalaria juncea) and buckwheat (Fagopyrum esculentum), post-soybean and post-maize (Pennisetum glaucum (L.) R. Br), Brachiaria brizantha in a randomized complete block design with four replicates. The analyzes were carried out at different times of development of the cover plants, seeking to evaluate plant height, green and dry mass of plants. All the cover plants analyzed performed well in the field. Millet showed a faster development when compared to brachiaria, crotalaria and buckwheat. It also presented higher production of dry and green mass. Millet showed a faster development when compared to brachiaria, crotalaria and buckwheat. It also had a higher production of dry and green pastry. The millet, when compared to the other cover crops evaluated, showed better after 30/04 (46 days after sowing) in relation to mass production. Buckwheat was the crop that presented better performance, initially developing faster than the others, but reaching a maximum growth point on 05/11 (57 days after sowing). The culture that presented the least impact by the previous crop was crotalaria, presenting smaller difference of mass production between the two treatments when compared to the other plants used. Brachiaria, due to its habit of growth, presented the lowest performance in the field, but it remains in the area for longer, making it possible for larger offspring. Muitas são as premissas do plantio direto, dentre elas podemos citar a utilização das plantas de cobertura como um método para melhorar as características de um solo. O intuído da utilização das plantas de cobertura é cobrir e proteger o solo de processos de erosão e degradação. Além de cobertura do solo, a palhada depositada pelas plantas de cobertura garantem ciclagem de nutrientes. Realizou-se a análise de quatro espécies de plantas de cobertura, milheto (Pennisetum glaucum (L.) R. Br), brachiaria (Brachiaria brizantha), crotalaria (Crotalaria juncea) e trigo mourisco (Fagopyrum esculentum), pós-soja e pós-milho em delineamento de blocos ao acaso com quatro repetições. As analises procederam-se em diferentes épocas de desenvolvimento das plantas de cobertura, buscando avaliar altura de plantas, massa verde e seca das mesmas. Todas as plantas de cobertura analisadas apresentaram um bom desempenho a campo. O milheto apresentou um desenvolvimento mais rápido quando comparado a braquiária, crotalaria e trigo mourisco. Apresentou ainda maior produção de massa seca e verde. O milheto, quando comparado as demais plantas de cobertura avaliadas, mostrou-se melhor a partir de 30/04 (46 dias após semeadura) em relação a produção de massa. O trigo mourisco foi a cultura que apresentou melhor desempenho, desenvolvendo-se inicialmente mais rápido que as demais, porem atingindo ponto máximo de crescimento em 11/05 (57 dias após semeadura). A cultura que apresentou menor impacto pela cultura anterior foi a crotalaria, apresentando diferença menor de produção de massa entre os dois tratamentos quando comparada as demais plantas utilizadas. A braquiária, devido seu habito de crescimento apresentou o menor desempenho a campo, porem permanece na área por mais tempo, viabilizando em entressafras maiores. 2022-09-16T14:26:09Z 2022-09-16T14:26:09Z 2018-11-27 bachelorThesis WOLF, Bruna Amanda.
