Ankara İli Ayaş İlçesi Çiftçilerinin Domates Tarlalarında Kullanılan Damla Sulama Sistemlerinin Performans Değerlendirmesi

Araştırmada domates yetiştiriciliği yapan çiftçilerin kullandığı damlama sulama sistemlerinin performansları ölçülmüştür. Bu amaçla İç Anadolu Bölgesinde Ankara ili Ayaş ilçesine bağlı köylerde bulunan bazı damla sulama sistemlerinin teknik performansları ölçülmüştür. Damla sulama sistemlerinin performansını ölçmek için her bir manifold hattı üzerinde 4 adet lateral hattı ve her bir lateralde 4 adet damlatıcı noktası seçilmiştir. Çalışmada, Uygulama Verimliliği (Ea) %29,5-63,6, Tekdüzelik Katsayısı (CU) %81,4-94,3, Dağıtım Tekdüzeliği (DU) %62,8-91,4, Emisyon Tekdüzeliği (AB) 58, %487,7, Alt Çeyrek Uygulama Verimliliği (AELQ) %33,4-%61,2 ve Alt Çeyrek Potansiyel Uygulama Verimliliği (PELQ) %52,5-78,9 olarak belirlenmiştir. Araştırmada elde edilen bulgulara göre, test edilen tüm alanlarda sistemde tasarım sorunlarının olduğu tespit edilmiştir.

Performance Evaluation of Drip Irrigation Systems Used in Tomato Fields of Ankara Province Ayaş District Farmers

The performances of drip irrigation systems used by farmers engaged in tomato cultivation were measured in the study. For this purpose, the technical performance of some drip irrigation systems in the villages of Ankara province Ayaş district in the Central Anatolia Region was measured. To measure the performance of drip irrigation systems, 4 lateral drip points on each manifold and 4 dripper points on each lateral were selected. In the study, the Application Efficiency (Ea) 29,5-63,6%, Uniformity Coefficient (CU) 81,4-94,3%, Distribution Uniformity (DU) 62.8-91.4%, Emission Uniformity (EU) 58,4-87,7%, Actual Application Efficiency of Lower Quarter (AELQ) 33,4%- 61,2% and Potential Application Efficiency of Lower Quarter (PELQ) 52,5-78,9% was determined. According to the findings obtained in the research, it was determined that there were design problems in the system in all tested areas.
