A pot experiment under greenhouse conditions was conducted during the grown season 2014 - 2015 in Agricultural College Research Station , Basrah University .

The aim was to study the effect of mixing composted plants residuals with soil and different concentration of Urea on some vegetative growth parameters of tomato hybrid ( Foton ).

Three types of growth media were designed as : (T1), 100% composted plant residues ; (T2), 1 composted plant residues : 1 soil based on volumes ; (T3), 2 composted plant residues : 1 soil based on volumes.

An equivalent of 0.05 (C1) , 0.1 (C2) , and 0.2 (C3) of total volume of growth media were added at media preparation.

Each treatment was replicated 5 times .

Plant height , number of branches , number of leaves , leaves area , shoot fresh weight , root fresh weight , shoot dry weight , root dry weight were recorded The results showed that higher growth parameters were associated with (T3) as compared with other treatments with higher shoot and root dry weights of 0.55 and 0.13 gm plant-1 , respectively .

Increasing urea level enhanced growth parameters of tomato seedling with higher shoot and root dry weights of 0.41 and 0.12 gm plant-1 , respectively at (C3) treatment .

Tomato seedling grown in (T3) media receiving Urea at level of 0.2% have higher growth parameters with shoot and root dry weights of 0.67 and 0.18 gm plant-1 , respectively.
