A field experiment was conducted in the research station of the Horticulture and Landscape Department, College of Agriculture, Tikrit University; to study the effect of mulch type on the growth and yield of two varieties of cauliflower during the 2017 – 2018 season. The experiment was carried out according to the split -plot layout within Randomized Complete Block Design (RCBD) and three replicates. Mulch types; black and yellow polyethylene in addition to the control treatment (non-mulch) were in the main plots, and varieties of cauliflower (Fuji Yama and White Cloud) were placed in sub-plots. Means were compared using Duncan multiple range test at 5% probability level. Results showed that there were no significant differences between mulching types in plant height, curd weight, curd length, and shoot weight. Meanwhile, there were significant increases in the number of leaves, leaf length, stem weight, compared with control. Curd diameter and chlorophyll contents increased significantly under black polyethylene mulching compared with both yellow mulching and control. On the other hand, there was no significant difference between the two varieties in all studied vegetative and yield parameters except leaf length which showed a significant increase with White Cloud variety (31.778 cm) compared with Fuji Yama (29.926 cm). The interaction between black mulching and White Cloud variety was significantly superior in the number of leaves (18.333 leaf.plant-1), plant height (8.083 cm), leaf length (34.556 cm), and chlorophyll contents (45.567 SPAD). The interaction between black mulching and Fuji Yama variety gave a significant increase in curd diameter (17.500 cm). Meanwhile, the treatments did not show any significant change in other characteristics of plants.
