Diante do exposto, o objetivo deste estudo foi avaliar as altera??es da comunidade de plantas daninhas em fun??o de diferentes sistemas de manejo de aduba??o do solo, por meio de an?lises fitossociol?gicas, nas culturas de alface e cenoura. Os estudos foram conduzidos no setor de Olericultura da UFVJM, no munic?pio de Diamantina, MG. O delineamento experimental utilizado foi o de blocos ao acaso, com oito tratamentos e quatro repeti??es. Os tratamentos, referentes aos diferentes manejos de aduba??o, foram: Convencional; Com Plantas Daninhas; Sem Plantas Daninhas; Composto; Crotal?ria; Crotal?ria mais Composto; e Lab-Lab e Lab-Lab + Composto. Durante o ciclo das culturas cultivadas, alface e cenoura, foram coletadas mais de 3.000 esp?cimes de plantas daninhas, representadas por 25 esp?cies, distribu?das em 11 fam?lias, 88% dicotiled?neas e 22% monocotiled?neas. As fam?lias de plantas daninhas com maior ?ndice de valor de import?ncia (IVI) em todos os est?dios de coleta foram Asteraceae, Brassicaceae e Poaceae. J? as esp?cies com maiores representatividade na ?rea foram Eleusine indica, Cyperus rotundus L., Galinsoga parviflora, Richardia brasiliensis, Oxalis latif?lia, Cynodon dactylon e Conyza canadensis, destacando-se entre elas, com maior densidade de plantas, C. rotundus. Observou-se de acordo com as ?pocas de avalia??o fitossociol?gicas decr?scimo na densidade populacional de plantas daninhas ao longo do per?odo experimental. E apesar da grande diversidade de plantas daninhas no ecossistema, as diferentes formas de aduba??o com plantas de cobertura foram capazes de promover modifica??es na comunidade das plantas daninhas.Submitted by Jos?

Programa de P?s-Gradua??o em Produ??o Vegetal, Universidade Federal dos Vales do Jequitinhonha e Mucuri, 2018.Few studies were developed to understand the population dynamics of weeds due to different systems of conduction and management of fertilization in the cultivation of oler?colas species. In view of the above, the objective of this study was to evaluate the changes of the weed community as a function of different fertilization management systems by phytosociological analyzes in lettuce and carrot crops. The studies were conducted in the Olericultura sector of the UFVJM, in the municipality of Diamantina, MG. The experimental design was a randomized block design, with four replications. Eight treatments were used to study the different management of fertilization: Conventional; With Weeds Without Weeds; Compound; Crotalaria; Crotalaria more Compound; Lab-Lab and Lab-Lab + Compound. During the crop cycle, more than 3,000 weed specimens, represented by 25 species, were collected in 11 families, 88% of which were dicotyledons and 22% were monocotyledons. The families with the highest value of importance (IVI) in all collection stages were Asteraceae, Brassicaceae and Poaceae. The most representative species in the area were: Eleusine indica, Cyperus rotundus, Galinsoga parviflora, Richardia brasiliensis, Oxalis latifolia, Cynodon dactylon and Conyza canadensis, with the highest density of C. rotundus plants. It was observed according to the phytosociological evaluation times decrease in weed population density throughout the experimental period. And although in ecosystems there was a great diversity of weeds, the cover plants were able to promote changes in the weed community.porUFVJMA concess?o da licen?a deste item refere-se ao ? termo de autoriza??o impresso assinado pelo autor, assim como na licen?a Creative Commons, com as seguintes condi??es: Na qualidade de titular dos direitos de autor da publica??o, autorizo a Universidade Federal dos Vales do Jequitinhonha e Mucuri e o IBICT a disponibilizar por meio de seus reposit?rios, sem ressarcimento dos direitos autorais, de acordo com a Lei n?
