In order to optimize use of fertilizer on nitrate content and Quality characteristics in green beans (Phaseolous Vulgaris) genotype Sunray, experimental form of split plot design based on randomized complete block in the 2010 Crop Agricultural Research Station Varamin three was carried out. In this experiment, main plots, including urea nitrogen level 1-250 Kg ha-1. 2-300 Kg ha-13-350 Kg ha-1. Three fertilizer treatments include potassium and zinc: 1-120 Kg ha-1potassium. 2 -Foliar of 6 per thousand Zn. 3-120 Kg ha-1potassium and foliar of 6 per thousand Zn (based on soil test) has sub plot. Results of interactions showed that the highest levels of nitrate in pods consumed 350 Kg ha-1of nitrogen (sulfur-coated urea) application of 120 kg (K) was185.4 mg kg-1, The least amount of nitrate in the pod was 250 Kg ha-1(N) combined potassium and foliar Zn with 76.4 mg/kg. Highest level of fresh pod yield was achieved treatment used 250 Kg ha-1N and combined K and foliar Zn on 4306.2 Kg ha-1. The lowest this characteristic was achieved the treatments used 350 Kg ha-1of nitrogen (sulfur coated urea) and potassium applications with 2298.6 Kg ha-1. The highest Number of cutting in pod, Number of pod in plant, Number of pod in m2were achieved treatment used 250 Kg ha-1and combined K and foliar Zn 17.1number, 210.6 number and 1680 number, respectively. The most of Pod length, Number of seed in pod that were achieved application used 250 (N) Kg ha-1and K 18 Cm and 5.6 number respectively. The highest levels of 100 seed weight was achieved treatment used 300 Kg ha-1and combined K and foliar Zn. The lowest characteristic was achieved the treatments used 3250 Kg ha-1of nitrogen and Zn foliar with 36.1 gr. The highest pod yield (4306.2 Kg ha-1) was provided by application of 250 kg Urea.ha-1 with K and Zn fertilizers, however the lowest pod yields (2298 Kg ha-1) was observed at 350 Kg ha-1Urea with K.
