To determine the effect of improving soil physical and chemical properties with use of subsoiling and animal manure on improved quantitative and qualitative traits of potato, an experiment was done in the Agricultural Research Station of Ardebil. To perform the experiment, the statistical factorial design based on completely randomized blocks design was used with 4 replications. In this experiment, the plowing operation in horizontal plots was applied with and without subsoiling. The animal manure factor was applied at four levels of controls as zero ton per hectare, 15 tons per hectare, 30 tons per hectare and 45 tons per hectare of animal manure at vertical and main plots. The effect of subsoiling on studied traits was not significant. The mutual effect of animal manure in the subsoiling on studied traits was not also significant. The animal manure impact on the traits of plant height, stem diameter, yield per plant, and number of nodes per plant, starch percentage, dry matter percentage and dry matter yield was significant, while showed no significant difference influencing the traits, including number of days to node-producing, number of stems, tuber mean weight per plant and the tuber size. In conjunction with quantitative traits, the manure treatment of 45 tons per hectare was the best, and the highest values of qualitative traits were also obtained in the control treatment.
