Influence of water deficit on growth and development of fruits valencia orange (Citrus sinensis Osbeck) in the piedmont of Meta department, Colombia
In Colombia the area planted with citrus is marginal when compared to the potential area for cultivation,due to factors such as water deficit, nutrition and efficiency of fruit formation.The aim of this study was to evaluate the effect of water deficit by controlled application of water throughsoil profile in orange crop var.Valencia (Citrus sinensis Osbeck) in the foothills Meta department, Colombia.The irrigation treatments (T) were: T1 = 100% of crop evapotranspiration (ETc); T2 = 50% ETc;T3 = control = 0% ETc. Irrigation was applied from the beginning of flowering in February to fruit formationin April 2011. The experimental design was randomized complete blocks with three replicatesper treatment. The variables evaluated were: soil moisture (θg), plant water status (Ψtallo), phenology,budding, flowering, formation, growth and fruit quality. The trees in the T1 had a higher number andsize of fruit, but found no differences (P> 0.05) in yield and quality compared to the control, the θg andΨtallo were different (P
