Abstract :
To study the effects of earthing up and barvar-2 phosphate biofertilizer together with Zn, Fe, Mn, Br, micronutrients foliar application on yield and yield components of potato, an experiment was conducted in Agricultural Research Center in Islamic Azad university of Ardabil, Iran, in 2009. The experiment was carried out using factorial design based on Randomized Complete Block design with three replications in two factors: The first one in two levels (earthing up in one time and its repetition in two times) and second factor in six levels (Control, barvar-2-phosphate biofertilizer, barvar-2phosphate biofertilizer together with foliar application of Zinc Sulfat, barvar-2phosphate biofertilizer together foliar application of Iron Sulfat, barvar-2phosphate biofertilizer together with foliar application of Manganese Sulfat and barvar-2phosphate biofertilizer together with foliar application of Boric acid). The results showed that the effects of earthing up and fertilizer except the number of tuber per plant, on plant height, Number of main branches per plant, Number of leaf per plant, tuber weight mean and tuber yield in per unit area were significant. Maximum tuber yield per unit area was obtained from experimental treatment of earthing up in two times and barvar-2 phosphate biofertilizer with foliar applications of Iron sulfat.
