Resumo: Nitrogen is one of the main nutrients for the bean plant, and its deficiency is very common. Because nitrogen also participates in construction of chlorophyll molecules, evaluation of n deficiency in the plant may be determined by indirect measurement of the chlorophyll content. The objective of this study was to use a chlorophyll meter for the detection of nitrogen deficiency. The study included 5 treatments (0, 50, 100, 150 and 200 kg ha-1 of N), with 10 repetitions, summing 50 pots with 8 dm3 of soil material. Ten readings were performed per pot at 30, 40 and 50 dae (days after emergency). The simple linear regression coefficients and those of second order were significant for all the study periods of this work, however the lack-of-fit was also significant, except for the behavior of the values obtained at 50 dae. In general, the values obtained with the chlorophyll meter trended to increase with elevation of N and with the advance of the plant development stages, indicating the potential for using this equipment to differentiate the various doses of nitrogen applied. It was verified that the different nitrogen doses applied influenced the values measured by the chlorophyll meter.

Como o nitrogênio também participa da constituição da molécula de clorofila, a avaliação da deficiência de N pela planta pode ser determinada pela mensuração indireta do teor de clorofila. Este trabalho teve como objetivo avaliar a possibilidade de utilização do medidor de clorofila na determinação da deficiência de N. O trabalho teve 5 tratamentos (0, 50, 100, 150 e 200 kg ha-1 de N), com 10 repetições, totalizando 50 vasos com 8 dm³ de material de solo. Foram feitas 10 leituras por vaso aos 30, 40 e 50 DAE (dias após emergência). Os coeficientes de regressão linear simples e de segundo grau foram significativos para todas as épocas estudadas neste trabalho, entretanto, a falta de ajuste também foi significativa, exceto para o comportamento dos valores obtidos aos 50 DAE. De modo geral, os valores obtidos com o medidor de clorofila tenderam a aumentar com o acréscimo da quantidade de N aplicado e com o avanço do estádio de desenvolvimento da planta, indicando o potencial da utilização deste equipamento para discriminar as diferentes doses de nitrogênio aplicadas. Foi possível observar que as diferentes doses de nitrogênio aplicadas influenciaram os valores do medidor de clorofila.Universidade Federal de Viçosa - UFV2013-04-18info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/reveng/article/view/28710.13083/reveng.v21i2.318Engineering in Agriculture; Vol. 21 No. 2 (2013); 122-128Revista Engenharia na Agricultura - REVENG; v. 21 n. 2 (2013); 122-1282175-68131414-398410.13083/reveng.v21i2reponame:Engenharia na Agriculturainstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/reveng/article/view/287/215Baesso, Murilo MesquitaPinto, Francisco de Assis de CarvalhoQueiroz, Daniel Marçal deSantos, Nerilson TerraCarneiro, José Eustáquio de Souzainfo:eu-repo/semantics/openAccess2023-01-19T13:08:25Zoai:ojs.periodicos.ufv.br:article/287Revistahttps://periodicos.ufv.br/revengPUBhttps://periodicos.ufv.br/reveng/oairevistaengenharianagricultura@gmail.com||andrerosa@ufv.br||tramitacao.reveng@gmail.com|| reveng@ufv.br2175-68131414-3984opendoar:2023-01-19T13:08:25Engenharia na Agricultura - Universidade Federal de Viçosa (UFV)false
