Economic evaluation of aminoethoxyvinylglycine (AVG) applications in 'Williams' pear cultivar
In modern fruit growing, it is not just the quantity of product but rather the quality of product that is becoming more prominent. For this reason, producers are focusing on cultural applications to produce higher quality fruit in line with consumer demands. However, to be adopted, these improved practices must have a positive effect on profitability. This study was conducted to evaluate the impact on profitability arising from the application of aminoethoxyvinylglycine (AVG) prior to harvest on the Williams pear cultivar. For this purpose, AVG was applied at the rate of 100, 125 and 150 ppm to the fruit and leaves of Williams pear cultivar at 3 different times (30, 21 and 7 days) before the estimated harvest period at the Fruit Research Institute, Isparta, Turkey, between 2012 and 2014. Only water + surfactant (Tween 20) was sprayed onto the control trees. It was found that AVG applications considerably reduced the pre-harvest fruit drop, delayed the harvest time and enhanced the fruit quality characteristics. As a result, the application of AVG at 100 ppm 30 days before the harvest time was determined to be the application with the highest gross profit.
