Evapotranspiration, leaf area índex and radicular development of irrigated beans
The evapotranspiration process (ETP), the leaf area index (LAI) as well as the radicular development of cv. IPA 74-19 beans (Phaseolus vulgaris) on a mean textured Red Yellow Podzolic soil of São Desidério Project were studied. The mean ETP was 3.9 mm/day, and the maximum, 5.3 mm/day, happened between late in the blooming and the pod shaping up. There was a positive linear correlation between ETP and class "A" tank evaporation (EV), with and everage coefficient of 0.65. During the culture cycle LA! Varied from 0.41 up to 3.73, and 83% in weight of root was concentrated in the 40 superficial centimeters of the soil.

Estudou-se, num Podrólico Vermelho-Amarelo de textura média do Projeto de Irrigação de São Desidério, a evapotranspiração (ET), o índice de área foliar (IAF) e o desenvolvimento radicular do feijão (Phaseolus vulgaris L.) cv. IPA 74-19. A ET média foi de 3,9 mm/dia e o máximo de 5,3 mm/dia, ocorrida entre o final da floração e a formação das vagens. Houve correlação linear positiva entre a ET e a evaporação do tanque classe A (EV), com um coeficiente médio de 0,65. Durante o ciclo da cultura o IAF variou de 0,41 a 3,73 m2/m2 e 83% em peso das raízes se concentraram nos 40cm superficiais do solo Pesquisa Agropecuaria Brasileira Pesquisa Agropecuária Brasileira 2014-04-17 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion application/pdf https://seer.sct.embrapa.br/index.php/pab/article/view/13404 Pesquisa Agropecuaria Brasileira; v.25, n.3, mar. 1990; 317-322 Pesquisa Agropecuária Brasileira; v.25, n.3, mar. 1990; 317-322 1678-3921 0100-104x por https://seer.sct.embrapa.br/index.php/pab/article/view/13404/7545 |
