英文摘要	In recent years, many farmers use new types of fertilizers to enhance fruit set and development and enhance the resilience of olive trees to climate change. In parallel, NO3- leaching in the soil and water threat the environment pointing toward a more sustainable nutrient management. This study investigated the effect of AMINO-16((c) ), a commercial product derived from hydrolysis/extraction of protein-rich plant material and contains sixteen L-amino acids, on vegetative growth, flowering, nutritional status, yield, and oil qualitative characteristics of 'Koroneiki' olives on the Mediterranean island of Crete in Greece. We conducted a field experiment with amino acid foliar sprays for two growing seasons in a commercial irrigated olive grove. Treatments comprised (a) no amino acid application (Control), (b) three applications (summer 2014, winter 2015, and spring 2015) of AMINO-16 (A16-A), and (c) one application (winter 2015) of AMINO-16 (A16-B). The A16-A treatment (three sprays) significantly increased the number of inflorescences, the fruit set, and the number of fruits per shoot. Fruit yield and olive oil yield were higher than those of the control by 10.6 and 18%, respectively. In addition, leaf nutrient levels and the quality characteristics of olive oil in both treatments were not differentiated from the control. Overall, foliar fertilization with amino acids could enhance plant growth. Future research using amino acids at different reproductive and vegetative stages of olive trees is likely to further improve olive oil yield and quality.
