Effect of regulated deficit irrigation practices on income in apple production

Abstract

It was aimed to determine the effects of regulated deficit irrigation practices except recommended irrigation on income in Braeburn apple variety grafted on M9 rootstock in this study. There were six different treatments (none deficit irrigation, I1; continuous deficit irrigation, I2; deficit irrigation between the 40th and 70th days after full bloom, DAFB, I3; deficit irrigation between the 70th and 100th DAFB, I4; deficit irrigation between the 100th and 130th DAFB, I5; deficit irrigation between the 130th and 160th DAFB, I6) in this study and their effects on yield and fruit quality and profitability were investigated. I3 and I6 with none deficit irrigation treatments were found to be most suitable practices in economic terms because of the high amount of quality fruits and yield values. Gross profit of the applications were determined as from highest to lowest, I1, I3, I6, I5, I4 and I2, respectively.
