The Influence of Colour and Thickness of Nylon Mulch on Soil Temperature, Moisture, Percent Germination and Some Growth Parameters of Cucumber (cucumis sativus L.) Seedlings
Heat, moisture and oxygen are important factors that has controlled seed germination, thus A 2 ×4 factorial greenhouse experiment was conducted to determine the influence of colour and thickness of nylon mulch on soil temperature, moisture, percent germination and selected growth indicators of cucumber (Cucumis sativus L.) seedlings in a completely randomized design (CRD), where the treatments; nylon colour (white and black) and thicknesses (0, 1.5, 3.0, and 4.5 mm) were replicated three times. The analysis of variance showed that the white nylon thickness had positive significant (P ≤ 0.05) influence on soil temperature, soil moisture, plant height and number of leaves, while black nylon thickness had positive significant (P ≤ 0.05) influence on soil moisture and plant height and a negative significant (P ≤ 0.01) influence on percent germination, it was also discovered that 1.5 mm thickness of the white nylon contributed significantly (p ≤ 0.05) to the parameters measured, therefore, white nylon of 1.5 mm thickness could be recommended as mulch material for cucumber production in a sandy clay soil.
