| Abstract:
Fruit thinning is an essential but a costly cultural practice in peaches. Fruit yield, size, and other quality attributes are greatly influenced by the degree and success of fruit thinning in peaches. To address the issue of thinning in peaches, we conducted an experiment in a random complete block design with 5 treatments, each with five replications. Treatments included: Ethrel at 0.3%, Ethrel at 0.6%, Urea 0.08%, Urea at 0.12% and manual thinning. The three cultivars used in this experiment were ‘Early Redhaven’, ‘Independence’ and ‘Fayette’. These sprinkling with aforementioned concentrations was performed in time of full inflorescence and in time of stone hardening. After the monitored fruit growth, the following quantities were measured: total yield per tree, number of fruits per branch linear meter and fruit weight. The experiment duration was two years in order to determine the climate effects of the year on the measured characteristics. The basic results from the experiment are: fruit thinning in production of peach and nectarine must be an obligatory treatment. Furthermore, manual thinning is proved to be the best way to perform noting that it must be performed by educated personnel which increases the costs of production. Among used chemical solutions the best one was with Ethrel 0.6%. | |
