Abstract
Abstract Future periods with limited water resources in Bangladesh will need the use of effective water‐saving technology, such as mulching, to increase potato production in a sustainable way. This study investigated the effect of plastic mulch on soil hydrothermal status and its consequent effect on potato production over 2 years in field experiments in Bogura, Bangladesh. We cultivated potato under four treatments: two coloured (black and blue) plastic mulches, strip tillage and no mulch. The black plastic mulch raised the soil temperature by 1.2–2.4°C in the early growth stages and by 0.4–1.2°C in the later growth stages compared to the no‐mulch treatment. This mulch raised soil moisture by 5.1–15.9% and reduced weed growth by 91% compared to no mulch. The nitrogen, phosphorus and potassium contents of the soil were significantly higher under the mulching treatments compared to no mulch. When compared to the blue and no‐mulch treatments, black mulch provided 31–34% and 45–48% more tuber yield of potato, respectively, which significantly improved the economic benefits under mulching treatments. Black plastic mulch is therefore suggested as a workable adaptation approach to increase potato production under limited water resources in northern Bangladesh and elsewhere with similar agroclimatic conditions.
