Resumo: | With the increasing global demand for energy, more attention has been directed to the production of oilseed plants as alternative energy sources, being irrigation one of the technologies used to increase yield. This research aimed to evaluate the effect of different soil water tensions and respective moisture depletions on castor bean (AL Guarany 2002 cultivar). The experimental design was randomized blocks, with five soil water tensions (15 kPa, 30 kPa, 45 kPa, 60 kPa and 75 kPa) and four replications. The water use efficiency (WUE) and yield were evaluated according to the soil water tension and respective moisture depletion. The soil coverage factor and plant height were also evaluated during the crop cycle, being respectively observed increases up to 125 and 200 days after transplanting. The WUE, following the order of racemes produced - primary (WUEP), secondary (WUES), tertiary (WUET) and total for the crop (WUEC) - decreased linearly with the increasing water stress, being the highest values observed for the treatment with the lowest tension (15 kPa). For all irrigation treatments, the highest WUE and yield were observed in secondary racemes. The highest yield was 1,994.14 kg ha-1, for the tension of 15 kPa and soil moisture depletion of 28%, while the lowest one was 773.91 kg ha-1, for the tension of 75 kPa and soil moisture depletion of 83%. |

Objetivou-se, com este trabalho, estudar o efeito de diferentes tensões e respectivos esgotamentos de água no solo, no cultivo da mamoneira (cv. AL Guarany 2002). Foi utilizado o delineamento de blocos ao acaso, com cinco tensões de água no solo (15 kPa, 30 kPa, 45 kPa, 60 kPa e 75 kPa) e quatro repetições. Foi avaliada a eficiência de uso da água (EUA) e a produtividade, em função da tensão de água no solo e respectiva fração de esgotamento de água. Além disso, avaliou-se o fator de cobertura do solo e altura das plantas, durante o ciclo da cultura, verificando-se o seu aumento até 125 e 200 dias após o transplantio, respectivamente. A EUA, seguindo a ordem dos racemos produzidos - primário (EUAP), secundário (EUAS), terciário (EUAT) e total da cultura (EUAC) - foi linearmente reduzida com o aumento da restrição hídrica, sendo os maiores valores observados para o tratamento à menor tensão (15 kPa). Para todos os tratamentos de irrigação, a maior EUA e produtividade foram observadas nos racemos secundários. A maior produtividade foi de 1.994,14 kg ha-1, para a tensão de 15 kPa e fração de esgotamento de água no solo de 28%, e a menor de 773,91 kg ha-1, para a tensão de 75 kPa e fração de esgotamento de água no solo de 83%.Escola de Agronomia - Universidade Federal de Goiás2014-09-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistas.ufg.br/pat/article/view/26235Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 44, n. 3, Jul./Sep. 2014; 287-293Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 44, n. 3, jul./set. 2014; 287-293Pesquisa Agropecuária Tropical; v. 44, n. 3, jul./set. 2014; 287-2931983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/pat/article/view/26235/17014Copyright (c) 2020 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessRios, Gervásio Fernando AlvesCarvalho, Luiz Gonsaga deSilva, Bruno MontoaniRezende, Fátima ConceiçãoPereira, Geraldo Magela2020-07-10T16:36:27Zoai:ojs.revistas.ufg.br:article/26235Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:56:04.189953Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true |
