Resumo: | The objective of this study was to define the adequate management of the nitrogen fertilization in the culture of grain sorghum, using as source the urea in soil of average texture. In the experiment conducted in 2001/02, was used a population density of 171,000 plants/ha-1, in direct plantation and was characterized by little precipitation. The assay realized in the agricultural year of 2002/03, was characterized by raised precipitation and was used 214,000 plants/ha-1, in conventional plantation. The experimental design was a randomized block with three repetitions and had been constituted by 21 treatments with nitrogen: 200 kg N/ha-1 in the base; 150 kg N/ha-1 in the base more 50 kg N/ha-1 on top on the 20, 44, 55, 66 and 74 days after the emergency of the plants; 100 kg N/ha-1 in the base more 100 kg N/ha-1 on top on the 20, 44, 55, 66 and 74 days after the emergency of the plants; 50 kg N/ha-1 in the base more 150 kg N/ha with on top on the 20, 44, 55, 66 and 74 days after the emergency of the plants; 200 kg N/ha-1 on top on the 20, 44, 55, 66 and 74 days after the emergency of the plants. In relation to the management with nitrogen fertilization in the of grain sorghum arrived the following: the treatments with 50 kg N/ha-1 in the base more 150 kg/ha-1 on top on the 66 and 74 days and 200 kg N/ha-1 on top on the 66 and 74 days in the low precipitation conditions of the agricultural year of 2001/02, had presented the lowest values of index of foliar area, biological productivity and grain yield; the nitrogen fertilization in the high precipitation conditions, registered in the agricultural year of 2002/03, provided to high index of foliar area and grain yield in hall the applied treatments; in experiment 2001/02, o the number of grains for panicle was the variable that more influenced in the grain yield and in 2002/03 it was the harvest index; by that is was observed in terms of grain yield, it could be said that good distribution of rain, the manegement with 200 kg N/ha-1 could be made until the 74 days the emergency, that would not reduce the productivity of grains |

No experimento conduzido em 2001/02, foi usado uma densidade populacional de 171.000 plantas/ha, em plantio direto e foi caracterizado por pouca precipitação. O ensaio realizado no ano agrícola de 2002/2003, foi caracterizado por elevada precipitação e foi usada uma densidade populacional de 214.000 plantas/ha, em plantio convencional. O delineamento experimental foi de blocos ao acaso com três repetições, constituído por 21 tratamentos com nitrogênio: 200 kg N/ha na base; 150 kg N/ha na base mais 50 kg N/ha em cobertura aos 20, 44, 55, 66 e 74 dias após a emergência das plantas; 100 kg N/ha na base mais 100 kg N/ha em cobertura aos 20, 44, 55, 66 e 74 dias após a emergência das plantas; 50 kg N/ha na base mais 150 kg N/ha em cobertura aos 20, 44, 55, 66 e 74 dias após a emergência das plantas; 200 kg N/ha em cobertura aos 20, 44, 55, 66 e 74 dias após a emergência das plantas. Em relação ao manejo com adubação nitrogenada na cultura do sorgo granífero, chegou-se as seguintes conclusões: os tratamentos com 50 kg N/ha na base e 150kg/ha em cobertura aos 66 e 74 dias e 200 kg N/ha em cobertura aos 66 e 74 dias nas condições de baixa precipitação do ano agrícola de 2001/02, apresentaram os mais baixos valores de índice de área foliar, produtividade biológica e rendimento de grãos; a adubação nitrogenada realizada nas condições de alta precipitação, registradas no ano agrícola de 2002/03, proporcionaram elevado índice de área foliar e rendimento de grãos em todos os tratamentos aplicados; no experimento de 2001/02, o número de grãos por panícula foi a variável que mais influenciou no rendimento de grãos e em 2002/03 foi o índice de colheita; pelo que foi observado em termos de rendimento de grãos, poderia se dizer que se houver boa distribuição de chuvas, o manejo com 200kg N/ha poderia ser feito até os 74 dias após a emergência, que não reduziria a produtividade de grãosapplication/pdfporUniversidade Federal de Santa MariaPrograma de Pós-Graduação em AgronomiaUFSMBRAgronomiaSorgoManejo de nitrogênioCNPQ::CIENCIAS AGRARIAS::AGRONOMIAComportamento do sorgo granífero em função do manejo de nitrogênioBehavior of grain sorghum in function of the nitrogen managementinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisLovato, CláudioGarcia, Danton Camachohttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4702954P8Ribeiro, Nerinéia Dalfollohttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4728724T9Lopes, Sidinei Joséhttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4700757Z3http://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4798949J3Silva, Pedro Celso Soares da50010000000940030030030030030020e42272-a0cf-42aa-a5d6-d410dff6fe816e07721e-874f-407b-ac13-22dadb402077bdd1dc69-344b-4644-a7d0-4a2d80fd57f0668b64b0-2ebc-462e-bb57-5c229645a422bb071e72-17cc-4d56-973f-0c1b1427597binfo:eu-repo/semantics/openAccessreponame:Biblioteca Digital de Teses e Dissertações do UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALpedro.pdfapplication/pdf1057122http://repositorio.ufsm.br/bitstream/1/3251/1/pedro.pdf42361fac2e1b2cda5bcff2b3824b2c24MD51TEXTpedro.pdf.txtpedro.pdf.txtExtracted texttext/plain230841http://repositorio.ufsm.br/bitstream/1/3251/2/pedro.pdf.txta5f6afb297f68f319a51d22f654934dbMD52THUMBNAILpedro.pdf.jpgpedro.pdf.jpgIM Thumbnailimage/jpeg5171http://repositorio.ufsm.br/bitstream/1/3251/3/pedro.pdf.jpg89a287e40d003aaaa93b8163375eb2e3MD531/32512017-07-25 10:53:03.185oai:repositorio.ufsm.br:1/3251Biblioteca Digital de Teses e Dissertaçõeshttps://repositorio.ufsm.br/ONGhttps://repositorio.ufsm.br/oai/requestatendimento.sib@ufsm.br||tedebc@gmail.comopendoar:2017-07-25T13:53:03Biblioteca Digital de Teses e Dissertações do UFSM - Universidade Federal de Santa Maria (UFSM)false |
