Abstract

In order to investigate the effect of NITROGEN and PLANT DENSITY on tuber macro elements uptake and C/N ratio of soil tested to produce high quality tuber POTATOes (Agria cultivar) in Ardabil region, Iran, a factorial experiment based on randomized complete block design with three replications was conducted in Ardabil, Iran in 2010. Factors included NITROGEN FERTILIZER levels: 0, 80, 160, and 200 kg ha-1 and plant densities: 5.5, 7.5, and 11 plant m-2. Results showed that the highest tuber NITROGEN percent and average tuber weight was observed at 80 kg ha-1 (equal to 160 kg ha-1 and 5.5 plant m-2. The highest Cupper and Phosphorus uptake by tuber was gained using 80 kg ha-1 NITROGEN and 7.5 plant m-2 density. Increasing FERTILIZER usage, led to the increase in Calcium and Potassium uptake and increment of soil NITROGEN content and decline of organic carbon and soil C/N ratio so that, by applying 200 kg ha-1 NITROGEN at a density of 7.5 and 11 plant m-2, the highest Calcium and Potassium uptake by tuber was resulted, respectively. With increasing NITROGEN up to 80 kg ha-1 and density, number and yield of tuber per unit area was increased and at 80 and 160 kg ha-1 at density of 11 plant m-2, the highest number and yield of tuber was achieved. So, application of 80 kg ha-1 at the density of 11 plant m-2 to gain the high quality tubers with the highest yield per unit area, and avoid of excess costs, is recommended.
