COMPARATIVE BETWEEN WATER LEVEL AND SOIL COVER MATERIAL ON GROWTH, PRODUCTIVITY AND WATER USE EFFICIENCY OF HOT PEPPER PLANT
Abstract: 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.
