An experiment was conducted in non heated plastic house in Al-Suwaira distinct at 2014-2015 season , to study the effect of spraying Zinc nutrient and Humic acid on Wogdan tomato variety.

Factorial RCBD used with three level from Zinc(ZnSO4.7H2O) 0 , 50 , and 100 mg.L-1 and four level from Humic acid, 0 , 2.5 , 5 , and 7.5 ml.L-1 , the results show : 1-Significant differences between Zin treatment on growth and yield parameters, the treatment (100 ml.L-1) gave higher values in plant height , No.

of leaves, Leaf area, Dry matter , chlorophyll, flowering period, No.

of , No.

of flowers, fruit weight, fruit No., and total yield , with increasing percent (27.38 , 13.4, 9.37, 9.42, 9.3, 10.1, 20.22, 10, 14.11, 27.7 and 43.09% respectively) compared with control treatment.

2-Significant differences between Humic acid treatment on growth and yield parameters, the treatment (5 gm.L-1) gave higher values in all parameter above , with increasing percent ( 10.34, 26.2, 5.91, 7.58, 7.8, 25, 36.58, 45.12, 28.57, 46.5, and 86.29% respectively) compared with control treatment.

3-Interaction treatment ( 100 ml.L-1 + 5 mg.L-1) gave significant higher values in leaf area, flowering period, flowering No., fruit weight, fruit No., and total yield.
