Spectral reflectance for growth and yield assessment of irrigated cotton. Author(s): BRANDAO, Z. N.; SOFIATTI, V.; BEZERRA, J. R. C.; FERREIRA, G. B.; MEDEIROS, J. C. The canopy reflectance using ground-based sensors has the potential to provide information on crop nitrogen content. The objective of this study was to determine relationships between canopy spectral... ... Repository: BDPA Publication year: 2015
Review of two decades of progress in the development of successful drip irrigation for onions. Author(s): SHOCK, C. C.; FEIBERT, E. B. G.; PINTO, J. M. The irrigation needs of long day onion (Allium cepa) have been extensively studied at Ontario, Oregon, over the past 22 years. Drip irrigation has compared favorably with furrow and sprinkler irrigati... ... Repository: BDPA Publication year: 2013
Irrigation water requirement for grapevines using two reference evapotranspitarion methods. Author(s): CONCEIÇÃO, M. A. F. The Northwest of São Paulo State, Brazil, is an important table grape producing area. There is a low rainfall period (April to October) in the region which coincides with the crop production cycle, ma... ... Repository: BDPA Publication year: 2009
Capacitive probe calibration in eutroferric red nitosol cultivated with irrigated forages. Author(s): SANCHES, A. C.; SOUZA, D. P. de; JESUS, F. L. F. de; MAFFEI, R. G.; MENDONÇA, F. C.; PEZZOPANE, J. R. M. Knowledge of soil water content is important for proper irrigation management because it allows estimating the required amount of water to be applied at the correct time. Capacitance sensors are an al... ... Repository: BDPA Publication year: 2017
Five methods to interpret field measurements of energy fluxes over a micro-sprinkler-irrigated mango orchard. Author(s): TEIXEIRA, A. H. de C.; BASTIAANSSEN, W. G. M. Energy balance measurements were carried out in a mango orchard during two growing seasons in the semi-arid region of Brazil. The actual evapotranspiration (ET) was acquired by eddy correlation (EC) a... ... Repository: BDPA Publication year: 2012
Behavior and water needs of sesame under different irrigation regimes: Analysis of growth. Author(s): PEREIRA, J. R.; GUERRA, H. O. C.; BEZERRA, J. R. C.; ZONTA, J. H.; ARAÚJO, W. P.; ALMEIDA, E. S. A. B. de The aim of this work was to evaluate the growth of sesame BRS 196 CNPA G4 in different irrigation depths (305, 436, 567 and 698 mm), applied on the basis of crop evapotranspiration? ETc (the depth of... ... Repository: BDPA Publication year: 2017
