The cheap-change: a new method to change cultivar in vineyards
Cheap-change is a very practical and economical method for changing cultivar in vineyards using chip-budding grafting method. This method has many advantages over other classical grafting applications (cleft, notch and bark). A unique hand machine has been developed and training system is largely preserved in this method. It is seen that it is applied in a very practical way and approximate 2700 grapevines can be grafted daily with a team of 6 people in studies has been observed. In wine grapes (Vitis vinifera L. Chardonnay, Sauvignon Blanc, Öküzgözü, Boğazkere and Narince) and table grapes (Vitis vinifera L. Sultana and Superior Seedless), cheap-change chip-budding grafting method has been made in İzmir/Torbali and Halilbeyli regions in 2013 and 2014. Data like grafting take (%), yield (kg vine‑1), average shoot length (cm) and grafting number (per day) are recorded. The grafting can be repeated several times in the same season. The grafting takes has ranged from 85.83% to 95.33% in first applications. In this method, there is no grapevine loss and the grape yield continues in the following year. These are the most important advantages of cheap-change method.
