%X Tomato (L.ycopersicon esculentum Mill.) cv. Rio Grande seedlings were nutritionally conditioned with solutions complete fertilizer N(60% NO3+40% NH4)-P-K (20-20-20) , N(30%NO3+70% NH4)-P-K (15-5-30) , the first two week N(60% NO3+40% NH4)-P-K (20-20-20) and later two week N(30%NO3+70% NH4)-P-K (15-5-30) and vice versa were applied in completely randomized experiment with three replications to determine the effect of nutritional regimes on tomato transplant growth. As nitrate rate increased from 30% to 60%, fresh shoot weight, plant height, stem diameter, leaf number, leaf area, shoot and root dry weights, and total chlorophyll increased. in the 750 mg/lit of N( 60% NO3+40%NH4 )-P-K (20-20-20) were decreased and it is with to increasing in stem diameter and total plant growth , application of N(60%NO3 + 40%NH 4 )-P-K(20-20-20) in the first two weeks of seedling growth and N(30%NO3+70%NH4)-P-K (15-5-30) in the last two weeks in the concentration of 200 mg/liter seedling height decreased.
