Quantitative and Qualitative Yield of Potato Tuber by Used of Nitrogen Fertilizer and Plant Density

Abstract

In order to investigate of quantitative and qualitative yield of potato tuber cultivar Agria, by applying nitrogen fertilizer levels and plant density a factorial experiment based on randomized complete block design was conducted with three replications, Ardabil, Iran. Factors were nitrogen levels (0, 80, 160 and 200 kg ha net nitrogen) and plant densities (5.5, 7.5 and 11 plant m ). Results showed that the most nitrogen 12
