Potato (Solanum tuberosum L.), a tuberous plant well known as a highly nutritional diet and an economic crop s, is the world's fourth largest production after rice, wheat and corn. Recent experiments have shown some potential places and varieties for cultivation in Cambodia. Thus, the experiment aimed to understand the response of the potential potato varieties to different planting dates in Sen Monorom town, Mondulkiri province (a mountainous area), Cambodia. The trail was laid out in randomized complete block design with 4 replications and 3 different planting dates namely October, November and December of 2018. The Coronada, certified seed from the Europlant International company in Germany, was the ideal variety used in the experiment and lasted 115 days from planting to harvest. Only the number of tuber per plant, tuber weight, weight per plant, and marketable yield were recorded. Suggested that planting date significantly affected to all measured parameters. Plot planting in December produced the highest number of tubers with an average of 9.3 tubers per plant while a similarity was noticed for October and November planting. However, the November planting surprisingly produced the highest weight per plant, heavier tuber and the highest marketable yield with 19.15 ton ha-1. The two other planting dates obtained an average yield of 14.49 and 12.39 ton ha-1 for October and December consequently. This is understandable that November planting and harvest at end February, which is the long cold and windy season with less rainfall, was the most comprehend planting season in Mondulkiri province, Cambodia.
