Abstract :
This study was carried out in 2003 in Damavand region to evaluate the effect of foliar application of complete fertilizer on yield and yield component of two potato‘s cultivars on a factorial in a randomized complete blocks design with four replications. In this experiment, two cultivars (Agria and Ajax) and four times of complete fertilizer foliar application (no application, complete emergence, tuber formation and tuber formation and tuber filling) were used.The results showed that there wasn‘t a significant difference between cultivars except for weight of tubers per plant and total yield, which Agric was superior to Ajax. the results showed that there was a significant difference between foliar application at tuber formation and tuber-filling treatment with another treatment and foliar application at tuber formation and tuber-filling produced higher yield. Finally it is recommended that for this region and other similar regions the superior cultivars like Agria to be planted and apply foliar application of complete fertilizer during tuber formation and tuber filling in order to increase the yield of potato.
