Resumo: | The development of the cotton crop is directly influenced by nitrogen nutrition, which is dependent on mineral fertilization. However, the management of nitrogen by this culture is complex, since large doses can also cause negative effects on crop yield. In this context, fine-tuning the dosage of N fertilizer, according to the crop demands, is essential to obtain high yields. This study sought to: I - establish the response curve of cotton yield to N fertilization, II – evaluate the capability of the optical sensor to estimate yield potential. The experiment was conducted in the agricultural year 2012/13 in an Oxisoil in the western region of the state of Bahia, in three areas with tropical climate, annual rainfall of 1600 mm yr-1 and a mean annual temperature of around 21 oC. The experiment was setup in a randomized block design with seven treatments and three replications. The treatments consisted of the following N doses: 0, 45, 90, 130, 150,180 and 220 kg ha - 1 applied at 43 days after sowing (DAS) in area 1 and 32 DAS in areas 2 and 3. The vegetation index (VI) readings were taken at three different times, corresponding to 63, 75 and 97 DAS in area 1 and 45, 57 and 80 DAS in areas 2 and 3, using the optical sensor N-Sensor ALS ® (YARA). For the different areas and VI readings the cotton yield was determined. The productivity of the cotton crop showed a quadratic fit with N doses studied in three experiments and the rates which achieved maximum economic efficiency were 164, 139 and 167 kg ha-1 of N for areas 1, 2 and 3, respectively. |

No entanto, o manejo do nitrogênio nesta cultura é complexo, uma vez que doses elevadas também podem provocar efeitos negativos na produtividade da cultura. Nesse contexto, o ajuste fino na dosagem de N fertilizante, de acordo com a demanda da cultura, é essencial para a obtenção de elevadas produtividades. O presente trabalho teve como objetivos: I - estabelecer a curva de resposta de produtividade do algodoeiro ao N fertilizante; II – avaliar a capacidade do sensor óptico em estimar o potencial produtivo. O experimento foi conduzido no ano agrícola de 2012/13 em um Latossolo Vermelho Amarelo, no oeste do estado da Bahia, em três áreas sob clima tropical, com precipitação anual de 1600 mm ano-1 e temperatura média anual em torno de 21 oC. O delineamento experimental foi em blocos ao acaso, com sete tratamentos e três repetições. Os tratamentos consistiram nas seguintes doses de N: 0, 45, 90, 130, 150, 180 e 220 kg ha-1 , aplicadas aos 43 dias após a semeadura (DAS) na área 1 e aos 32 DAS nas áreas 2 e 3. As leituras de IV foram realizadas em três épocas, correspondentes aos 63, 75 e 97 DAS na área 1 e aos 45, 57 e 80 DAS nas áreas 2 e 3, utilizando o sensor óptico N-Sensor LS® (YARA). Adjacente aos estádios e pontos de leitura de IV, foi realizada a determinação de produtividade do algodoeiro. A produtividade da cultura do algodoeiro apresentou um ajuste quadrático com as doses de N nos três experimentos estudados e a dose que atingiu a máxima eficiência econômica foi a de 164, 139 e 167 kg ha-1 de N para as áreas 1, 2 e 3, respectivamente.Universidade Federal de Viçosa - UFV2015-02-23info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/reveng/article/view/47310.13083/reveng.v23i1.522Engineering in Agriculture; Vol. 23 No. 1 (2015); 57-64Revista Engenharia na Agricultura - REVENG; v. 23 n. 1 (2015); 57-642175-68131414-398410.13083/reveng.v23i1reponame:Engenharia na Agriculturainstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/reveng/article/view/473/331Geib, Leandro Ricardo de NadaiAmado, Telmo Jorge CarneiroBragagnolo, JardesBortolotto, Rafael PivottoNora, Douglas Dallainfo:eu-repo/semantics/openAccess2023-01-19T13:22:29Zoai:ojs.periodicos.ufv.br:article/473Revistahttps://periodicos.ufv.br/revengPUBhttps://periodicos.ufv.br/reveng/oairevistaengenharianagricultura@gmail.com||andrerosa@ufv.br||tramitacao.reveng@gmail.com|| reveng@ufv.br2175-68131414-3984opendoar:2023-01-19T13:22:29Engenharia na Agricultura - Universidade Federal de Viçosa (UFV)false |
