Review of two decades of progress in the development of successful drip irrigation for onions. 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
Spectral reflectance for growth and yield assessment of irrigated cotton. 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
Irrigation water requirement for grapevines using two reference evapotranspitarion methods. 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. 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. 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
Capacitive probe calibration in eutroferric red nitosol cultivated with irrigated forages. 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
Onion response to irrigation criteria for two varieties at two plant populations. Past research at the Malheur Experiment Station demonstrated the sensitivity of onion yield and grade to soil water tension (SWT) (Shock et al. 2000). The ideal SWT for initiating irrigations for drip... ... Repository: BDPA Publication year: 2014
Five methods to interpret field measurements of energy fluxes over a micro-sprinkler-irrigated mango orchard. 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
Water demand and flows in the São Francisco River Basin (Brazil) with increased irrigation. Most activities that support economic growth in the São Francisco Riber Basin (Brazil) need water. Allocation of the water resources to each competing use needs quantification in order to develop an i... ... Repository: BDPA Publication year: 2009
Water demand prospects for irrigation in the São Francisco River: Brazilian public policy. Abstract. This study analyzed how irrigation expansion in the São Francisco Hydrographic Region (SFRH) could affect water availability in four physiographic regions: Upper, Middle, sub-Middle, and Low... ...
