Abstract
The experiment was conducted in greenhouse at the vegetable research farm of Horticulture Department, College of Agriculture/ University of Dohuk- Iraq, subsidy with the MCC-ZSVP organization, interior the plan of tomato crop production during the growing season of 2015-2016, to investigate the effects hybrids (Royal & Sandra) and humic acid (0, 0.4, 0.8 & 1.6) g.l-1 on growth and yield of Tomato (Lycopersicum esculentum, Mill.) grown under plastic house condition. Results showed that Royal hybrid had significant increase in some vegetative (leaves area cm2, plant high m and chlorophyll) and majority yield characters (No. of fruit f.plant-1, plant yield kg.plant-1, early yield and total yield t.ha-1), while Sandra hybrid had significant increase in (fruit weight g and total acidity%), there were no significant effect of hybrids on yield characteristic (vitamin c, TSS, N, P and K) % in fruit . Spraying tomato with humic acid concentration significantly increase vegetative growth like (leaves area cm2, plant high cm and chlorophyll %), and also humic acid increased quantitative and qualitative yield characters especially 0.8g.l-1 (No. of fruit f.plant-1, plant yield kg.plant-1, early yield t.ha-1, total yield t.ha-1, TSS% and N% in fruit), while 1.6g.l-1 of humic acid had higher increased K% in fruits, where as no significant differences occurred in (fruit weight g, vitamin C, total acidity % and P% in fruit).
