Abstract
In order to evaluate the agronomic efficiency, physiological, recovery physical and nitrogen consumption in different levels of fertilizer in varieties of potatoes, an experimental farm in 2011 in the research farm of the university Mohaghegh Ardebili of Iran. Experiment in Factorial randomized complete block design with three replications. Table of variances showed that the effect of cultivar was significant on physiological efficiency, apparent recovery and nitrogen using in (α=1%) of probability but it was not significant on agronomic nitrogen use efficiency. Fertility effect was significant on all traits. Results of means comparison showed that applying 100 kg of pure nitrogen was more effective than using 200kg on all studied traits. Between cultivars Marfona in the trait of physiologic efficiency and Clone B6 for apparent recovery efficiency and nitrogen use efficiency, had the most values. The interaction of cultivar on nitrogen fertilizer showed that using 100 kg of nitrogen fertilizer increased agronomic nitrogen use efficiency four times in compared with applying 200 kg in all studied cultivars.
