Abstract

This study was carried out at the High Center for Agricultural Technologies (ALghiran) in Tripoli, Janzour district. Evaporation pan (A) for green house condition was used to estimate water requirement for Pepper crop using drip irrigation system. The pan coefficient was calculated by using the FAO Penman-Monttiet equation (F.P.M), which was recommended by the Food and Agriculture Organization (FAO) to use it to estimate crop water requirements, the pan coefficient as a general average for all months was (0.875).This study aims to determine the relationship between crop productivity and the amount of water used in the drip irrigation system and to determine the value of the appropriate evaporation pan coefficient for calculating the water requirements for plants grown inside greenhouses. For this purpose, two types of pepper were cultivated (Al Sahem and Al-Furat); So that four different irrigation treatments (100%, 85%, 70% and 55%) of the water requirements were given from the evaporation pan reading. The irrigation treatment (85%) gave the best productivity, then the irrigation treatment 70%, then 100%, and the lowest productivity when the irrigation was 55%.  As for the efficiency of water use, the (Al Sahem) gave a good level of efficiency for using water between the different irrigation treatments, while the water use efficiency of the (Al-Furat) was lower compared to the (Al Sahem).
