| Résumé : |
The adoption of drip irrigation in the Mitidja west region has accompanied the development of a market-gardening basin supplying the whole country. However, despite the support programmes that have been launched, little is known about the conditions of use and control of this technique, particularly irrigation performance. This study aims to ases performance at different scales (boom,sector and farm) by establishing analysing pressure (P) and flow (Q) variability profiles, and then the Q-P relationship. To do this, a preliminary survey was carried out among 15 farmers, in conjunction with local authorities and system installers, with the aim of taking into account the connditions of adoption, installation and use. Then 3 farms were selected fom the 15, on the basis of a typology established according to the results of the survey.A total of 288 flow measurements and 176 pressure measurements were taken (repeated 3 times).
The best reslts (∆P≤0.2 bar; DU≥89%, flow rate staility and compliance with ISO 9261 and ASABE standards) were obtained in the operation involving an installation withe the same boom diametr and the same type of integrated self-regulating drippers. It was installed by a fairly well-trained and experienced installer in the field. Another farm, on the other hand, showed the least satisfactory results, with fairly significant instability in the flow rate, with rates as high as DU<61%t ∆P>69%. This installation was carried out workers with 3to 5 years experience in using the system, using booms of different diameters and lengths and different type of non-self-regulating drippers, both integrated and in-line. The distance from the station head also seems to have an effect. This study represents a contribution to the evaluation of drip irrigation performance. On the one hand, it highlihts the importance of the elements included in the analysis relating to the installation and use of the system, but on the other hand it also opens up new perspectives, in particular integrating other components not taken into consideration. |
