Irrigation requirements and transpiration coupling to the atmosphere of a citrus orchard. 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... ... Repository: BDPA Publication year: 2011
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
Two-dimensional spatial distribution modeling of sprinkler irrigation. 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... ... Repository: BDPA Publication year: 2021
Evapotranspiration and biomass modelling in the Pontal Sul Irrigation Schem. 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... ...

Infrared thermometry to schedule irrigation of common bean. 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... ... Repository: BDPA Publication year: 2004
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
Nitrate concentration in the soil solution as affected by irrigation water concentration in fertirrigation. Author(s): ANDRADE NETO, T. M. de; COELHO, E. F.; SANTANA, J. A. do V.; SANTANA JUNIOR, E. B.; ALVES, M. da S. The use of fertirrigation provides larger fertilizer application efficiency, reduction on labor and increases in the benefit-cost relationship to farmers. The inadequate use of fertilizer in fertirrig... ... Repository: BDPA Publication year: 2008
Water application efficiency of a microsprinkler irrigation system in banana crop. Author(s): SILVA, A. J. P. da; COELHO, E. F.; MIRANDA, J. H. de The food production will be limited in a near future due to the shortening of water resources. The irrigated agriculture must seek for solutions in order to guarantee high yields using water with high... ... Repository: BDPA Publication year: 2008
