abstract

pepper is one of the nutrition demanding vegetable. in order to compare n fertilizer uptake and plant numbers per area unit, an experiment was conducted with replications. in which fertilizer was the main factor and included ammonium nitrate in 7 levels (0, 80, 160, 240 kg /ha-1) and 40+40, 80+80, 120+120 kg/ha-1 (in 2 stages i.e. half of these amounts appliedpre planting and the other half of itside dressed in flowering stage).the second factor (plant density) comprised of 3 levels (25000, 35000 and 50000). the data such as: fruit numbers per plot and per plant, plant’s height yield per plant, fruit weight and prematurity percentage were detemined. according to the results simple and interaction effects of factors on yield and fruit numbers were significant, but n fertilizer had no significant effect on plant’s height. data means comparison showed that green pepper’s yield was 100% higher than the control when using 240 kg n ha-1. resultsalso showed that by increasing the plant numbers per area unit, the yield of each plant and fruit numbers in each plant were decreased.
