A comparison between the water requirement the cucumber crop by the two methods of surface irrigation and drip irrigation and their effect on some chemical characteristics of the crop.

Abstract

The study has been done since 2020  in Abi Jersh farm at the Faculty of Agriculture, Damascus University , aims to determine the water requirement of the cucumber crop  (hybrid cultivar , prince) using each irrigation method (dripping - surface dripping)  three times  according to the design of random sectors, and irrigation was carried out as soon as  the moisture of the soil reached 80% of field capacity.

The results showed the superiority of drip irrigation compared to surface irrigation in the water requirement , which reached ( 3099.5 -5597.7 m³/ha) respectively.

Also superiority of drip irrigation compared to surface irrigation with yield increasing and water irrigation saving and water use efficiency, With an increase ratio in yield by(14.6-11.2 ton/ ha)  respectively , with an irrigation water saving ratio by (55.4 % ), and increase ratio in water use efficiency by(4.95 -3.04 kg/m³ ) respectively .

Also the use of drip irrigation resulted in a increase in dry matter by (5.4-3.3% ) respectively, and in addition to an total sugar by (6.8-4.6 %) respectively, and  with vitamin C fruits by (4.4- 3.2 mg /100 g) respectively
