2010-648 MODEL VALIDATION FOR MAIZE IRRIGATION SCHEDULING IN PLOVDIV REGIONZornitsa Popova 1, Luis S. Pereira 21 N.Poushkarov Institute of Soil Science, Sofia, Bulgaria2 Agricultural Engineering Research Center, Institute of Agronomy, Portugal Abstract:This paper reports on using independent historic datasets relative to 6 years experiments (1985-1990) with diverse irrigation treatments of maize for further testing the […]

2010-642 USE OF IRRIGATION SCHEDULING REGIME AS DROUGHT INDICATORMilena Kercheva 1, Zornitsa Popova 11 Institute of soil science, Bulgaria Abstract:The impact of droughts on agricultural crops depends mainly on net precipitation distribution during the vegetation period and soil physical properties. Most of drought indices do not reflect the complicate interaction between current climate conditions, soil […]
