The use of different soil covers is well-known agricultural practice. All around the world people are using mulch to increase vegetable growth and yield. The use of plastic film helps to get cleaner fruits and to limit weed growth. There have been conducted studies in Latvia on the use of various synthetic mulch materials in strawberry cultivation, but there is not enough information about the effects of coloured plastic film soil cowers’ impact on cucumbers. The aim of the study was to determine the effect of coloured polyethylene mulch’s on yield of cucumbers cultivars ‘Pioneer’ F1 and ‘Madita’ F1. The research was conducted during the vegetation period of years 2014, 2015 and 2016. The experiments were established in gardening cooperative „Atpūta” owned summer cottage area in Svēte parish, Jelgava Municipality. In all experimental years, cucumbers were planted on 18 June, when the first true leave developed (BBCH 11). Six different coloured polyethylene films were used: yellow, red, blue, black and white film. A field without polyethylene coverage was a control group. The test was conducted in two replicates, including four plants. The largest harvest was obtained from the yellow mulched plots. White polyethylene film is not recommended for soil mulching due to decrease of cucumber yield in all experimental years. The effect of films’ colour depended on climatic conditions in growing season.
