Abstract: 

Modern fertilization recommendation must optimize crop yield and quality and minimize chance of negative environmental effects due to over fertilization. In this research, Romaine lettuce type (Lactuca sativa L.) was used as a case study vegetable crop to determination of nutrient requirements to nitrogen and phosphorus in Varamin. Soil texture was loamy and soil family was fine, mixed, active, thermic, typic haplocambids. Experiment conduct to split plot sign in blocks of randomize sign with three times in level five 0, 100, 150, 200 and 250 kg.Nha-1 and five level 0, 37.5, 50, 62.5 and 75 kg P2O5.ha-1. Fresh head yield and nitrate of leaf measured. Based on results recommended 250 kgNha-1 and 50 kg P2O5 ha-1 for maximum yield and legal level of nitrate in lettuce.
