An experiment was conducted during winter season of 2011/2012 at Al– Bourjesiah Experimental Research Station.

Zubair belong to Ministry of Agriculture include desert area southern of Iraq under plastic tunnels.

The aim of was to study the effect of foliar application of some mixtures of chemical fertilizers and pesticides on vegetative growth parameters, flowering and yield of hybrid tomato plant cv.

" Hatouf ".

The experiment included 26 factorial treatments resulting from the interaction between 13 foliar application of chemical fertilizers dissolved in water at average of 1.75 g/ l water to each of MAP.

DAP and NPK and with two pesticides (Match and Score) at concentration of 0.5 ml/l water alone or mixing with pesticides and two spraying times (Morning or night).

Randomized Complete Block Design was used with three replicates.

Duncan's Multiple Range Test was used at probability of 5% to compare mean variations.

Results can be summarized as follows:- Plants sprayed with Score + Match + NPK mixture gave a significant increase in number of lateral branch/ plant, dry weight/plant, total number of inflorescences/ plant, plant yield and total yield/donum (34.6.

61.7 g.

27.0 inflorescence.

2.496 kg and 10.982 ton) respectively, while plants sprayed with Score + Match + DAP mixture gave a significant increase in plant length (92.8 cm), whereas it have no effect on leaves number/ plant.

Time of spraying have no effect on all studied parameters.

while the interactions between the two factors have no effect on studied parameters except for the number of lateral branch/ plant.

The highest number was 35.3 branch from treatment Score + Match + NPK mixture in the morning.
