The experiment was carried out during spring season 2016 to study the effect of foliar spraying treatment with Tecamin Flower 2.5 ml/L in comparison with distilled water, on growth of three hybrids of tomatoes at two different levels of irrigation (100 and 50 % of field capacity). Three sprays were conducted started from flowering with two weeks’ interval. The results showed that ‘Finenss’ hybrid had significant differences in plant height, branches per plant and leaves number per plant. ‘Hadeer’ hybrid had superiority in dry matter ratio and content of chlorophyll in leaves. Reducing the level of irrigation resulted in a significant decrease in plant height, total branches number, versus an increase in the leaves number per plant, total leaves area and the percentage of dry matter. The results showed that the treatment with Tecamin flower led to a significant increase in all indicators studied. The interaction treatments shoed that Hadeer hybrid irrigated in level 50 % and spraying of nutrient solution (Tecamin flower) had a significant increase in dry matter ratio and chlorophyll content in leaves. While the hybrid Finenss which irrigated in level 100 % with nutrient solution (Tecamin flower) had a significant increase in leaves number per plant and total leaves area.
