The impacts of climate change on food security have increased interest in research and investments in irrigation technologies and agricultural water management. Agricultural practices such as mulching help to conserve soil moisture by reducing evaporation and mitigate the adverse effects of water stress on crops, especially in semi-arid environments. This study investigated the combined effects of irrigation schedules and different mulching technologies on the growth and yield of two varieties of chilli pepper-Legon 18 (Capsicum frutescens L.) and Kpakpo shito (Capsicum chinense)-in the Guinea Savannah agro-ecological zone of Ghana. Soil temperature and moisture content as well as plant growth parameters were collected over the growth period. The number of days taken for first and 50% flowering and fruiting were also recorded. Total fruit yield and crop water productivity were estimated after harvest. Results. Show that the combination of irrigation at 100% ETcrop every three days and...
