Seed germination studies and effect of different treatments on dormancy breaking and early seedling growth of Cucurbita maxima and Cucumis sativus seeds was investigated in the laboratory. Growth parameters such as percentage germination, Shoot length, Root length, Leaf area and Numbers of nodes were evaluated. Standard procedures were used in the evaluation of the growth parameters. The results indicated that in all the two plant species tested, growth parameters were significantly (P=0.05) by treatment with concentrated H2S04, soaking with 0.1% KNO3, chilling treatment and removal of seed coat were stimulated above the fresh seeds treatment. Treatment with concentrated H2S04, soaking with 0.1% KNO3 and chilling treatment showed highest promotion of percentage germination and early seedling growth parameters. Cucurbita maxima showed better responses to treatments with concentrated H2S04, soaking with 0.1% KNO3 and chilling treatment than Cucumis sativus. Results from this research indicates that dormant seeds of Cucurbita maxima and Cucumis sativus should can be overcome by treatment with concentrated H2S04, soaking with 0.1% KNO3 and chilling or removal of seed coats as this can promote the germination and early seedling growth process of Cucurbita maxima and Cucumis sativus seeds improving its yield and productivity thus proving to be a very useful pretreatment operational practice for farmers.
