Özet
The increasing global population and food security concerns are rapidly raising the demand for sustainable approaches to increasing agricultural productivity. Triacontanol (TRIA) is a non-toxic primary alcohol that can be naturally obtained from plant waste and has regulatory effects on growth, yield, and physiological processes in plants. Investigating the contribution of such natural growth regulators, which are low-cost and accessible to farmers, to yield increase in potato farming is of great importance for sustainable agriculture. This study was conducted in a total of 270 pots under greenhouse conditions using a randomized block design with 5 different TRIA doses, 6 different application methods (control, IAA, SA, GA3, ABA, and mix) and 3 different application approaches (foliar, soil, and soil + foliar). The study aimed to determine the effects of TRIA on the Agria potato variety (Solanum tuberosum L.) and to identify the most effective combination of application methods for yield enhancement. According to the results, foliar application of TRIA at a dose of 10 µM yielded the most effective outcomes compared to other methods and doses. Under greenhouse conditions, foliar-applied 10 µM led to a 122.97% increase in tuber weight, a 94.89% increase in tuber/plant weight, a 41.96% increase in plant height, and a 53.48% increase in plant weight compared to 0 µM TRIA. At 20 µM TRIA dose applied from leaves, a 26% increase in protein was achieved in the above-ground part and a 15.07% increase in protein in the tuber part compared to 0 µM. In conclusion, it has been determined that optimized TRIA applications are an effective ergonomic approach that can increase potato production under controlled growing conditions.
