Resumo: | The lowland areas with agricultural production in the southern half of Rio Grande do Sul are predominantly cultivated with rice, flood irrigated. This irrigation method uses more water and emits larger amounts of greenhouse gases compared to other methods. In addition, the soils of these areas present low physical quality for aerobic crops, which associated with the low slope, results in problems with water excess and/or deficit for crops. Such characteristics often prevent the rotation of rice with other crops. Given these challenges, experiments were carried out with rice and soybean crops in the 2016/17 and 2017/18 agricultural seasons, which were summarized in two scientific papers. The first paper refers to the experiments with the soybean crop, and aimed to evaluate the effects of irrigation systems and soil management on soil physical properties and soybean growth and grain yield cultivated in lowlands. Two factors were studied, being irrigation systems and soil management. Between the irrigations systems, it was tested sprinkler irrigation, border irrigation and rainfed. For soil management, the treatments were composed by tillage, no-tillage, tillage with raised-seedbed and no-tillage with raised-seedbed. The second scientific paper addresses rice crop and the objective was to evaluate irrigation systems and soil management for rice cultivated in lowlands. It also had two factors, being the irrigation systems composed by the sprinkler, border and flood irrigation and the soil management composed by conventional tillage, no-tillage and conventional tillage with raised-seedbed. In the results, the variables analyzed were the soil physical properties (bulk density, total porosity, soil resistance to penetration, macroporosity and microporosity), irrigation water requirement, root system distribution, yield components, grain yield, total water productivity and irrigated water productivity. Soil management with conventional tillage increases soil resistance to penetration near 0.1 m depth in lowland soils. In years of uneven rainfall, the soil management in no-tillage without irrigation results in an increase of 20% in soybean grain yield compared to conventional tillage non-irrigated, and irrigation increases grain yield by 37%. For rice, sprinkler irrigation resulted in higher irrigation water productivity (3.82 kg m-3), compared to border (1.64 kg m-3) and flood (1.21 kg m- 3). It was concluded that sprinkler irrigation can be used as an alternative to flood irrigation, in no-tillage, for rice and soybean cultivation, with higher irrigation water productivity and that soil management does not interfere with rice grain yield when flood irrigated. |

Esse método de irrigação utiliza mais água e emite maiores quantidades de gases de efeito estufa, comparado a outros métodos. Além disso, os solos dessas áreas apresentam baixa qualidade física para cultivos aeróbicos que, associada à baixa declividade, acarreta problemas de excesso e déficit hídrico para esses cultivos. Tais características, muitas vezes impedem a rotação do arroz com outras culturas. Diante do exposto, foram conduzidos experimentos com as culturas do arroz e da soja, nas safras agrícolas 2016/17 e 2017/18, que resultaram em dois artigos. O primeiro artigo refere-se a experimentos com a cultura da soja, e teve como objetivo avaliar os efeitos de métodos de irrigação e manejos do solo nas propriedades físicas do solo e no crescimento e a produtividade de grãos da cultura da soja em terras baixas. Dois fatores foram estudados: Sistemas de irrigação e Manejo do solo. Como tratamentos no fator sistemas de irrigação, foram utilizadas as irrigações por aspersão, por faixas e sem irrigação. Para os manejos do solo, os tratamentos foram: preparo convencional do solo, semeadura direta, preparo convencional com camalhão e camalhão em semeadura direta. O segundo artigo, contempla a cultura do arroz e teve como objetivo avaliar métodos alternativos de irrigação e de manejos do solo para cultivo de arroz em terras baixas. Também foram estudados dois fatores, com os tratamentos de irrigação por aspersão, por faixas e inundação, para os sistemas de irrigação, e para os manejos do solo foram o preparo convencional, semeadura direta e camalhão. Nos resultados dos artigos são apresentadas as propriedades físicas do solo (densidade do solo, porosidade total, macroporosidade e microporosidade), a necessidade de irrigação, distribuição do sistema radicular, componentes e a produtividade de grãos, produtividade da água total e da água de irrigação. O manejo do solo com preparo convencional aumenta a resistência do solo à penetração mecânica próximo a 0,1 m de profundidade em solos de terras baixas. Em anos de chuvas irregulares, o manejo do solo em semeadura direta sem irrigação resulta em um incremento de produtividade de grãos de soja de 20%, em relação ao manejo convencional não irrigado, e a irrigação, aumenta a produtividade de grãos em 37%. No arroz, a irrigação por aspersão resultou em uma maior produtividade da água de irrigação (3,82 kg m-3), em relação a irrigação por faixas (1,64 kg m-3) e inundação (1,21 kg m-3). Conclui-se que a irrigação por aspersão, pode ser utilizada como alternativa à irrigação por inundação, em semeadura direta, para cultivo de arroz e soja, com maior produtividade da água de irrigação e que o manejo do solo não interfere na produtividade de grãos de arroz quando irrigado por inundação.porUniversidade Federal de Santa MariaCentro de Ciências RuraisPrograma de Pós-Graduação em Engenharia AgrícolaUFSMBrasilEngenharia AgrícolaAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/openAccessArrozCamalhãoIrrigação por aspersãoPlantio diretoSojaRiceRaised seedbedSprinkler irrigationNo-tillageSoybeanCNPQ::CIENCIAS AGRARIAS::ENGENHARIA AGRICOLAManejo de solo e água em soja e arroz em terras baixasSoil and water management for soybean and rice in lowlandsinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisCarlesso, Reimarhttp://lattes.cnpq.br/4740272927848914Petry, Mirta Teresinhahttp://lattes.cnpq.br/0358609083747198Marchesan, Eniohttp://lattes.cnpq.br/2740617028203037Michelon, Cleudson Joséhttp://lattes.cnpq.br/7524461221954574Alberto, Cleber Maushttp://lattes.cnpq.br/2747295128900648http://lattes.cnpq.br/2361134063710575Giacomeli, Robson5003000000086001a6ccd1d-16e8-4110-910c-7178d86e0944b51fa8f3-c2f8-4c87-a00f-30790f8887135576e48a-0ed8-4b43-8d05-c4580270b5f1181fc2d0-618b-4e42-abdb-fd5e83fb71ab72fbced4-1d8c-409c-b78b-9c1ca50adf6fed22747e-b107-4eae-869a-721f965c0198reponame:Manancial - Repositório Digital da UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALTES_PPGEA_2019_GIACOMELI_ROBSON.pdfTES_PPGEA_2019_GIACOMELI_ROBSON.pdfTese de Doutoradoapplication/pdf3497628http://repositorio.ufsm.br/bitstream/1/18619/1/TES_PPGEA_2019_GIACOMELI_ROBSON.pdff57460d6f8deb40b7e1c3ff4bb89435cMD51CC-LICENSElicense_rdflicense_rdfapplication/rdf+xml;

description |
The lowland areas with agricultural production in the southern half of Rio Grande do Sul are predominantly cultivated with rice, flood irrigated. This irrigation method uses more water and emits larger amounts of greenhouse gases compared to other methods. In addition, the soils of these areas present low physical quality for aerobic crops, which associated with the low slope, results in problems with water excess and/or deficit for crops. Such characteristics often prevent the rotation of rice with other crops. Given these challenges, experiments were carried out with rice and soybean crops in the 2016/17 and 2017/18 agricultural seasons, which were summarized in two scientific papers. The first paper refers to the experiments with the soybean crop, and aimed to evaluate the effects of irrigation systems and soil management on soil physical properties and soybean growth and grain yield cultivated in lowlands. Two factors were studied, being irrigation systems and soil management. Between the irrigations systems, it was tested sprinkler irrigation, border irrigation and rainfed. For soil management, the treatments were composed by tillage, no-tillage, tillage with raised-seedbed and no-tillage with raised-seedbed. The second scientific paper addresses rice crop and the objective was to evaluate irrigation systems and soil management for rice cultivated in lowlands. It also had two factors, being the irrigation systems composed by the sprinkler, border and flood irrigation and the soil management composed by conventional tillage, no-tillage and conventional tillage with raised-seedbed. In the results, the variables analyzed were the soil physical properties (bulk density, total porosity, soil resistance to penetration, macroporosity and microporosity), irrigation water requirement, root system distribution, yield components, grain yield, total water productivity and irrigated water productivity. Soil management with conventional tillage increases soil resistance to penetration near 0.1 m depth in lowland soils. In years of uneven rainfall, the soil management in no-tillage without irrigation results in an increase of 20% in soybean grain yield compared to conventional tillage non-irrigated, and irrigation increases grain yield by 37%. For rice, sprinkler irrigation resulted in higher irrigation water productivity (3.82 kg m-3), compared to border (1.64 kg m-3) and flood (1.21 kg m- 3). It was concluded that sprinkler irrigation can be used as an alternative to flood irrigation, in no-tillage, for rice and soybean cultivation, with higher irrigation water productivity and that soil management does not interfere with rice grain yield when flood irrigated. |
