Keywords: Tomato hybrid, Humic acid and storage period


The study was conducted to undertake the response of two tomato hybrids (Royal and Sandra), to humic acid at level (0, 0.4, 0.8 and 1.6) g.L-1 during storage time on the postharvest quality of tomato fruits. Plants were grown at vegetable research field, Department of Horticulture, College of Agriculture, University of Dohuk, Kurdistan during the growing season of 2015-2016, in plastic house. Fruits of the two hybrids were harvested manually in the early morning at the maturity stage of fruit growth.

We did not observed a clear difference between the two hybrids in fruits quality characteristics. While, when plant of tomato hybrids treated with humic acid cuased significantly increase in V.C., total acidity, N%, K%, and P% of fruit. In addition, when storage period of fruits was advanced from 7to 14 days, a significant increase was observed in total soluble solids of fruits, on the contrary recorded a significant decreased with progressing time of fruit storage in acidity, vitamin C, N% and K%. The interaction effect of the three factors under study on the quality of fruits showed a difference behavior depending on the response of studied features.
