Resumo: Intercropping using legumes is one of the ways to protect the main crop, and in long term improve the physical and chemical properties of the soil. The aim of this work was to evaluate the intercropping of Colocasia esculenta (L.) Schott (taro) and the tropical legume Crotalaria juncea L. (sunn hemp), cutting sunn hemp at ten periods during the cycle. The experiment was carried out under field conditions between 09/23/2010 and 06/04/2011. It consisted of 11 treatments related to the 10 cutting times of sunn hemp (55, 70, 85,100, 115, 130, 145, 160, 190, and 220 days after sowing - DAS) plus a control of taro with no sunn hemp. During the cycle, taro was evaluated for plant height and incidence of leaf burn. At the time of cutting the sunn hemp, the plant height, fresh and dry matter masses, and nutrient content of the biomass were calculated. During taro harvest, we evaluated the productivity of the mother rhizomes and classified the cormels. Taro plants shaded by sunn hemp showed a lower incidence of leaf burn. The sunn hemp cut from 145 DAS onwards affected the yield of comercial rhizomes and total and agroeconomic indexes. Sunn hemp cut up to 130 DAS provided better performance of taro, without compromising productivity and economic indicators, with the highest amounts of N and K observed in the biomass cut at 115 DAS.

O objetivo do trabalho foi avaliar o consórcio taro (Colocasia esculenta (L.) Schott) com crotalaria (Crotalaria juncea L.) com o corte da crotalaria em 10 épocas durante o ciclo. O experimento foi conduzido a campo entre 23/09/2010 a 04/06/2011. Consistiu de 11 tratamentos referentes a 10 épocas de corte da crotalaria (55, 70, 85, 100, 115, 130, 145, 160, 190 e 220 dias após a semeadura – DAS), mais o taro solteiro (controle). Durante o ciclo, foi avaliada a altura de planta e incidência da queima de folhas do taro. No momento do corte da crotalaria foram calculados a altura de planta, massas de matéria fresca e seca e teor de nutrientes da biomassa. Durante a colheita do taro, foi avaliada a produtividade de rizomas mãe e das classes de rizomas filhos. As plantas de taro sombreadas pela crotalaria apresentaram menor incidência de queima das folhas. O corte da crotalaria a partir dos 145 DAS afetou a produtividade de rizomas comerciais e total e índices agroeconômicos. O corte da crotalaria até 130 DAS proporcionou melhor desempenho do taro, sem comprometer a produtividade e indicadores econômicos, com as maiores quantidades de N e K observadas na biomassa cortada aos 115 DASRevista Ceres2018-11-27T19:41:39Z2018-11-27T19:41:39Z2018-01info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlepdfapplication/pdf2177-3491http://dx.doi.org/10.1590/0034-737x201865010006http://www.locus.ufv.br/handle/123456789/22611engv. 65, n. 1, p. 35- 43, jan./ fev. 2018Colombo, João NacirPuiatti, MárioSilva Filho, Jaime Barros daSantos, Ricardo Henrique SilvaDias, Luiz Antônio dos Santosinfo:eu-repo/semantics/openAccessreponame:LOCUS Repositório Institucional da UFVinstname:Universidade Federal de Viçosa (UFV)instacron:UFV2024-07-12T07:46:22Zoai:locus.ufv.br:123456789/22611Repositório InstitucionalPUBhttps://www.locus.ufv.br/oai/requestfabiojreis@ufv.bropendoar:21452024-07-12T07:46:22LOCUS Repositório Institucional da UFV - Universidade Federal de Viçosa (UFV)false
