Resumo: | This study aimed to evaluate strategies for weed management on the production of watermelon, in no-tillage and conventional systems, after melon cultivation. The experiment was conducted in split plots, distributed in randomized block design, with four replications. In the plots were evaluated the tillage systems (no tillage and conventional tillage) and in the sub-plots were evaluated nine systems of weed management (covered with polyethylene film, with weeding at 14 days after transplanting (DAT); at 14 and 28 DAT, at 14 and 42 DAT, at 14, 28 and 42 DAT, at 28 DAT, at 28 and 42 DAT, at 42 DAT and without weeding control). It was evaluated density and dry weight of weeds at 14, 28 and 42 DAT and at harvest time (80 DAT). For the watermelon were evaluated number of marketable fruit per plant, total fruit number per plant, average weight of marketable fruit per plant, average mass of fruits (total) per plant, marketable and total yield of fruit, besides the qualitative characteristics (longitudinal and transverse length, pulp thickness and firmness, pH and soluble solids). The no-tillage system reduced the density and dry mass of weeds and proportionated fruit yield bigger than the conventional tillage system. In conventional tillage was necessary to carry out weeding at 14 and 28 DAT, while in no-tillage system, despite the lower weed infestation, there was need to do only one weeding between 28 and 42 DAT. In the treatments without weeds control there was reduction of 100 and 35.7% in marketable yield, respectively, for conventional and no-tillage systems. The no-tillage system and cover with polyethylene film in the conventional tillage allow the accomplishment of a second crop in the area in succession to the melon, reducing weed interference and providing satisfactory results in the characteristics of watermelon production. |

O experimento foi conduzido em blocos casualisados com quatro repetições, no esquema de parcelas subdivididas. Nas parcelas foram avaliados dois sistemas de plantio (plantio direto e plantio convencional) e nas sub-parcelas foram avaliados nove sistemas de manejo de plantas daninhas (cobertura com filme de polietileno de polietileno; com capinas aos 14 dias após o transplantio (DAT); aos 14 e 28 DAT; 14 e 42 DAT; aos 14, 28 e 42 DAT; aos 28 DAT; aos 28 e 42 DAT; aos 42 DAT e testemunha sem capinas). Foram realizadas avaliações de densidade e massa seca de plantas daninhas aos 14, 28 e 42 DAT e por ocasião da colheita (80 DAT). Para a melancia, foram avaliados número de frutos comercializáveis por planta; número total de frutos por planta; massa média frutos comercializável por planta; massa média frutos (totais) por planta; produtividade comercializável e total, além de características qualitativas dos frutos (comprimento longitudinal e transversal; espessura de polpa; firmeza da polpa, pH e teor de sólidos solúveis). O sistema de plantio direto reduziu a densidade e a massa seca das plantas daninhas e proporcionou produção de frutos superior ao sistema de plantio convencional. No sistema de plantio convencional houve necessidade de realização de capinas aos 14 e 28 DAT, enquanto que no sistema de plantio direto, apesar da menor infestação de plantas daninhas, houve necessidade de realização de apenas uma capina entre 28 e 42 DAT. Quando a cultura conviveu com as plantas daninhas durante todo o ciclo houve redução na produtividade comercial na ordem de 100 e 35,7%, respectivamente, para os sistemas de plantio convencional e direto. O sistema de plantio direto e o filme de polietileno no sistema de plantio convencional permitem a realização um segundo cultivo na área em sucessão ao meloeiro, reduzindo a interferência de plantas daninhas e proporcionando resultado satisfatório nas características de produção da melancia.Coordenação de Aperfeiçoamento de Pessoal de Nível SuperiorUniversidade Federal Rural do Semi-ÁridoBRCentro de Ciências Agrárias - CCAUFERSAPrograma de Pós-Graduação em FitotecniaGrangeiro, Leilson CostaCPF:02108750460http://lattes.cnpq.br/1788174638876714Freitas, Francisco Claudio Lopes deCPF:69935319687http://lattes.cnpq.br/0060989785573065Lima, Jailma Suerda Silva deCPF:03424556483http://lattes.cnpq.br/4377585882022311Moura Filho, Edmondson ReginaldoCPF:02128215471http://lattes.cnpq.br/0758203802472512Silva, Márcio Gledson Oliveira da2016-08-12T19:15:41Z2011-05-182010-07-29info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfapplication/pdfSILVA, Márcio Gledson Oliveira da.
