Abstract
Drip irrigation is one of important technique of watering especially during unstable and uneven distributed rainfall due to global climate change. It minimizes water loss hence may increase the CWP (Crop Water Productivity). The purpose of this study was to evaluate the drip irrigation combined with soil mulching to CWP of cash crops. This research was conducted from October 2020 to February 2021 at Jumantono, Karanganyar Regency, Indonesia. The experiment was arranged in the Strip Plot design with 3 factors, namely type of irrigation (drip and conventional) as main plot; mulch (control, silver black mulch, and straw mulch) also commodities (paddy and chili) as the sub-plot with 3 replications. Parameters observed were biomass and Crop Water Productivity (CWP). The results showed drip irrigation combined with soil mulching resulted in higher CWP at both chili and paddy.
