Viabilizar a produ??o do alho com caracter?sticas agron?micas ?timas, produ??o menos agressivas ao meio ambiente, com qualidade nutricional, e, ainda com competi??o de mercado, tem sido uma das principais estrat?gias de pesquisadores. Este trabalho teve como objetivo, avaliar o momento ideal de desseca??o para implanta??o de sistema de plantio direto para cultivo do alho, bem como realizar a fitossociologia das plantas daninhas. Foram conduzidos dois experimentos sendo o primeiro em casa de vegeta??o, em vasos de polietileno, esquema fatorial 2 x 6+2 (dois sistemas de aduba??o (org?nica e mineral), 6 ?pocas de plantio (tr?s ?pocas antes, no dia, e duas ?pocas depois da desseca??o com glyphosate), al?m dos dois tipos de aduba??o sem palhada, com 4 repeti??es. Avaliou nessa primeira etapa a altura de planta e n?mero de folhas. O segundo experimento foi realizado em campo em blocos ao acaso com 5 tratamentos, correspondentes a tr?s ?pocas de desseca??o da braqui?ria (dez dias antes, no dia e dez depois do plantio do alho, cultivar Gigante Roxo, e o plantio sem capina e sem desseca??o e plantio com capina manual, com 4 repeti??es. No primeiro experimento n?o se observou diferen?a entre as formas de aduba??o, contudo, plantas se desenvolveram melhor para desseca??o a dez dias antes do plantio. No segundo experimento, a desseca??o foi satisfat?ria, exceto quando feita ap?s o plantio do alho. A fitossociologia realizada aos 40 dias mostrou as esp?cies Oxalis latifolia e Galisonga parviflora foram as mais presente, e na fase final da colheita mostrou pouca diferen?a entre os tratamentos sendo Oxalis latifolia a esp?cie com maior densidade relativa. As fam?lias predominantes foram Asteraceae e Oxalidaceae. Conclui-se que a palhada com Urochloa brizantha controla plantas daninhas e pode ser usado na cultura do alho desde que dessecada antes do plantio.Disserta??o (Mestrado) ? Programa de P?s-Gradua??o em Produ??o Vegetal, Universidade Federal dos Vales do Jequitinhonha e Mucuri, 2019.In Brazil, garlic (Allium sativum L.) occupies the fourth place in economic importance among the vegetables. Enable garlic production with optimal agronomic characteristics, less aggressive production to the environment, with nutritional quality, and, even with market competition, has been one of the main strategies of researchers. The objective of this work was to evaluate the ideal desiccation moment for the implantation of no -tillage system for garlic cultivation, as well as to perform weed phytosociology. Two experiments were carried out, the first one in a greenhouse, in polyethylene pots, 2 X 6 + 2 factorial scheme (two organic and mineral fertilization systems), 6 planting times (three seasons before, no day, and two seasons). After the desiccation with glyphosate), besides the 5 types of fertilization without straw, with 4 repetitions.The three periods of desiccation of the brachiaria, the planting without grass and without desiccation and planting with the manual weeding, with 4 replications. Difference between fertilization phases, though, has been improved for desiccation for ten days prior to planting.Phytosociology at 40 days showed the following variables: Oxalis latifolia and Galisonga were the main present and the final phases of the sample were no longer reached between Oxalis latifolia aum with higher relative density. The predominant families were Asteraceae and Oxalidaceae. It is concluded that the straw with broccoli is a weed and can be used in the garlic culture from the desiccated before planting
