Abstract: In order to study the effect of organic and chemical fertilizers on some morpho-physiological traits of potato (cv. Agria), an experiment was conducted based on randomized complete block design (RCBD) with three replications during 2013 in Ardebil region. The fertilizer treatments were included; control (without fertilizer), 100% chemical fertilizer (urea), farm manure, farm manure + 50% urea, Pars Humic Plus organic fertilizer, Pars Humic Plus + 50% urea, Bird Hume organic fertilizer and Bird Hume + 50% urea. Results indicated that farm manure + 50% urea was superior to other fertilizer treatments in terms of all the traits other than chlorophyll content and dry matter percentage. Humic Plus + 50% urea had the highest chlorophyll content (SPAD = 47.34) in the leaf as compared to other treatments; whereas, Bird Hume fertilizer treatment produced the highest dry matter % (27.45).The treatments of farm manure + 50% urea and 100% urea fertilizer indicated the highest tuber yield among the fertilizer treatments. Also the farm manure + 50% urea fertilizer treatment had the highest gross income among the treatments. By increasing the organic fertilizers in the cropping systems the problems of chemical fertilizers will be reduced that is in consistent with sustainable agriculture.
