 Author(s): Santana Junior, E. B.; COELHO, E. F.; Santos, M. R. dos; Silva, A. J. P. da; Reis, J. B. R. da S.; Pereira, B. L. da S. Information on soil hydrodynamic processes assists in explaining the soil-water-plant relationship and has practical applications to irrigation management, such as the definition of soil water sensor... ... |
 Author(s): ANDRADE NETO, T. M. de; COELHO, E. F.; SANTANA, J. A. do V.; SANTANA JÚNIOR, E. B.; ALVES, M. da S. Fertilizers are salts that may increase irrigation water salinity, therefore, fertirrigation management should consider aspects like the injection solution. The electrical conductivity of soil solutio... ... |
 Author(s): MARIN, F. R.; ANGELOCCI, L. R. Crop evapotranspiration (ETc) was measured as evaporative heat flux from an irrigated acid lime orchard (Citrus latifolia Tanaka) using the aerodynamic method. Crop transpiration (T) was determined by... ... |
 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... ... |
 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... ... |
 Author(s): BORGES JÚNIOR, J. C. F.; ANDRADE, C. de L. T. de Irrigation can provide significant agronomic and financial returns on agricultural activity. The maximization of the benefits obtained from irrigation depends, among other factors, on the water use ef... ... |
 Author(s): ARAÚJO, L. M.; TEIXEIRA, A. H. de C.; BASSOI, L. H. In order to make feasible the use of irrigated areas of the Pontal Sul Irrigation Scheme in Petrolina, State of Pernambuco, Brazil, modelling of real evapotranspiration (ET) and plant biomass producti... ... |
 Author(s): SOCCOL, O. J.; RODRIGUES, L. N.; BOTREL, T. A.; ULLMANN, M. N. The objective of this work was to evaluate the efficiency of a hydrocyclone to separate sand in irrigation water. To do this, it an experiment was conducted where the hydrocyclone was operated with pr... ... |
 Author(s): SIMOES, W. L.; DRUMOND, M. A.; OLIVEIRA, A. R. de; GONCALVES, S. L.; GUIMARÃES, M. J. M. The high luminosity rates and high annual average temperatures of the Brazilian semiarid region, combined with the use of irrigation and adaptability of the sunflower crop to local climate, favor incr... ... |
 Author(s): LOBO, F. A.; OLIVA, M. A.; RESENDE, M.; LOPES, N. F.; MAESTRI, M. ABSTRACT- The objective of this work was to determine the critical irrigation time for common bean (Phaseolus vulgaris L. cv. Carioca) using infrared thermometry. Five treatments were analyzed. Canopy... ... |
