Abstract: 

In order to study the effect of different nitrogen and zeolite levels on qualitative and quantitative traits of potato Lcv. Agria this experiment was carried on factorial design based on CRBD with three replications, on Moradi farm located in 5 km far from Arak, in spring 2008. Factors were included three levels of nitrogen fertilizer rates (96, 184, 276 kg/ha) and four levels of zeolite rates (0, 2, 4, 6 t/ha). The results showed that consumption of nitrogen sulfate and zeolite was on number of stems per plant, main stem height of the tallest, shoot dry eight, total weight bulb weight; bulb diameter by more than 5.5 cm gland ha in the 1% level of probability was significant. Also, comparison of characteristics indicated that interactions on the total weight of zeolite and nitrogen Drbvth bulb weight, bulb diameter by more than 5.5 cm and bulb yield per unit area was significant. Gland with the highest amount of 276 kg of pure nitrogen and 6 tons of zeolite was 61 t/ha significant difference with the consumption of 184 kg N treatment and six tons of zeolite was not. So with less nitrogen fertilizer consumption to 184 kg/ha can function without a significant reduction in nitrogen fertilizer efficiency will to act.
