Abstract :
This research was conducted to evaluate the effects different planting beds on the mini-tuber production Agria and Savalan cultivars of potato in both laboratory and greenhouse of "Ardabil Potato Seed Production Company of Dasht-Zarrin" during 2009. Experiment was factorial based on completely randomized complete block design with three replications and two factors. Factor A consisted of two potato cultivars (Agria and Savalan) and factor B of four planting beds (Biolan, Terracult, Cocopeat and soil as control). Analysis of variance of measured traits showed that differences of planting beds, cultivars and interaction between cultivar × planting bed concerning the number and weight mini-tuber per m2, average size of mini-tuber and plant height were significant. Savalan produced highest mini-tuber number, weight per m2 andplant height, and Agria had the highest average size of mini-tuber when Terracult planting bed was used. Correlation between mini-tuber weight per m2 with plant was positive and significant.
