Leaf water potential of coffee estimated by landsat-8 images. Author(s): MACIEL, D. A.; SILVA, V. A.; ALVES, H. M. R.; VOLPATO, M. M. L.; BARBOSA, J. P. R. A. de; SOUZA, V. C. O.; SANTOS, M. O.; SILVEIRA, H. R. DE O.; DANTAS, M. F.; FREITAS, A. F. de; SANTOS, J. O. DOS Traditionally, water conditions of coffee areas are monitored by measuring the leaf water potential throughout a pressure pump. However, there is a demand for the development of technologies that can... ... Repository: BDPA Publication year: 2020
Evaluation of mathematical equations for estimating leaf area in rapeseed. Author(s): DALMAGO, G. A.; BIANCHI, C. A. M.; KOVALESKI, S.; FOCHESATTO, E. Repository: BDPA Publication year: 2019
Indirect estimation of leaf area in genotypes of 'Conilon' coffee (Coffea canephora Pierre ex A. Froehner). Author(s): ESPINDULA, M. C.; PASSOS, A. M. A. dos; ARAUJO, L. F. B.; MARCOLAN, A. L.; PARTELLI, F. L.; RAMALHO, A. R. Leaf area is an important parameter in agronomic and physiological studies; thereby, the techniques used for its determination should be simple, fast and accurate. The objective of this study was to e... ... Repository: BDPA Publication year: 2018
Calibration of chlorophyll hand-held meter based on vineyard NDVI zones for estimation of leaf N content. Author(s): SILVA, T. M. M. da; COSTA, B. R. S.; OLDONI, H.; FOSCHINI, M. M.; BASSOI, L. H. The monitoring of chlorophyll content in grapevine leaves allows us to evaluate their N status, assisting with the information for the decision make about nutrient rate and application time to the vin... ...

The probability of repeating the agronomic response can be evalu... ... Repository: BDPA Publication year: 2019
Optimal conditions for conidial germination and infection of European pear leaves by Diplocarpon mespili. Author(s): NUNES, C. C.; ALVES, S. A. M.; BOGO, A.; CASA, R. T.; CZERMAINSKI, A. B. C.; SILVA, F. N. da The epidemiology of Entomosporium leaf spot (ELS) affecting European pear is poorly understood, which limits the development of an effective management strategy. In vitro assays were conducted to stud... ... Repository: BDPA Publication year: 2016
Morphogenesis of dwarf elephant grass clones in response to intensity and frequency of defoliation in dry and rainy seasons. Author(s): GOMIDE, C. A. de M.; PACIULLO, D. S. C.; COSTA, I. de A.; LIMA, A. M.; CASTRO, C. R. T. de; LEDO, F. J. da S.
