Abstract: 

The study was carried out during spring season 2021, in the nursery of the faculty of Agriculture at Tishreen University, in order to study the effect of four concentrations of Triflurallin: 1.5, 2, 2.5, 3 ml/L, on the production and inhibition of budding of potato tubers during storage for six months. Results showed the  superiority of the treatment with a concentration 2 ml/L in the total production, the standard production, and the productivity per plant: 5218 kg, 5129 kg/ dunum,1273 g/plant respectively; also there was a significant  decrease in the percentage of buds after 150 days storage with the treated tubers at a concentration of 3ml/l, It also showed a significant superiority in reducing the average number, length and weight of buds sprouted on one tuber; and the lowest natural weight loss was with the treatment concentration 2.5 ml/L after 90-120-150 days of storage. The study showed a decrease in the percentage of dry matter and starch and there were no significant differences between treatments at the end of storage.   

Key words: Potatoes, Storage, Yield, Triflurallin,  Budding.
