Abstract
This trail was carried out during three successive seasons 2008,
2009 and 2010 to study the effects of regulated deficit irrigation
during specific phenological stages “RDI” and partial rootzone
drying “PRD” on growth and productivity of ”Early Superior”,
”Superior” and ”Thompson Seedless” grapevine cultivars. Water
deficit at 50% level (compared to fully irrigated control) was
imposed during different growth stages i.e. the 1st stage of berry
growth “RDI1”, the 2nd stage of berry growth “RDI2” , the 3rd stage
of berry growth “RDI3” or post harvest “RDI4”.
