A study was conducted during 1998-2000 at the Western Colorado Research Center in Colorado, USA, to determine the effect of different coloured (clear, black and green) plastic mulch in combination with subsurface drip irrigation on Kabocha squash [Cucurbita maxima] yield, sugar content in terms of Brix level, and water savings compared to producers practice of surface irrigation without mulch. The study also evaluated the effect of planting method (transplanting versus direct sowing) on squash yield. Soil in the study area was classified as clay loam. In 1998, there was a significant difference in the amount of irrigation water applied between the subsurface drip and furrow irrigated plots. The water applied in the subsurface drip irrigated plots was equivalent to, on average, 19 in/acre. An equivalent of 76 in/acre, on average, were applied to the furrow irrigated plots. Water application by subsurface drip irrigation in 1999 slightly improved and an equivalent of 18 in/acre was applied, whereas an equivalent of 82 in/acre was applied by furrow irrigation. Transplanted squash produced higher yields compared to direct sowing, except for drip irrigated plots with directly sown squash under black mulch. However, the colour of plastic mulch showed no statistically significant influence on the yield components measured for Kabocha squash except for planting method. The Brix level was 11.31 for the furrow irrigated, directly sown plots with no mulch. The highest value of 15.19 was observed for directly sown squash in subsurface drip irrigated plots with green mulch.
