Two field experiments were conducted during the two successive winter seasons of 2020-2021 and 2021-2022 on the experimental farm belonging to the Central Laboratory for Agricultural Climate, Agricultural Research Center, Giza Governorate, and Egypt. The study comprised three irrigation levels (50, 75, and 100% of estimated water requirement based on climatic data) and four soil cover treatments namely transparent polyethylene mulch (PE), rice straw (RS), date palm fiber wastes (DPf) and control (bare soil). Hot pepper seeds (Capsicum annuum L.), Super Noura F1 hybrid. Hot pepper transplants were cultivated in the field in the first week of September for both seasons. The main results show that using 100% water level led to increased vegetative and yield of hot pepper during both seasons followed by using 75% while deficit irrigation gave the lowest hot pepper growth and yield. Using 75% water level gave the highest water use efficiency. Using PE mulch led to increasing the soil temperature during the growth season followed by rice straw mulch whereas the date palm fiber wastes mulch decrease soil temperature during both seasons. Moreover, PE treatment led to an increase in the growth and yield of hot pepper during both seasons. Control treatment combined with a 50% water level decreased the growth and productivity of hot pepper during the two seasons.
