| Abstract | ||
| ABSTRACT : Tomato (Lycopersicon esculentum var Carmello F1)seedlings were grown in order to study the effect of three levels of urea fertilizer (46%N) (400 ، 600 and 1200 kg/h) on nutrient balance, mineral contents of tomato leaves through different growth stages. A Completely Randomized Block Design experiment was conducted in three levels of nitrogen fertilizer with 3 replicates, for this experiment This experiment was done in the plastic house unit/ college of Agriculture/ Baghdad University at 2001/2002. Results indicated that N fertilization significantly affected plant yield and leaf content of N, P, K during plant season. Also, the nutrient ratios and their balances in the plant show unchanging in N/10P, N/K and 10P/K ratios during growth season, with the indication that there was no effect of sample date on detection of nutrient balance and it could use to study the balance of nutrient within the plant at any time of growth | ||
