Kahramanmaraş Yöresinde Yaygın Olarak Kullanılan Damla Sulama Damlatıcılarının Hidrolik Özelliklerinin Değerlendirilmesi

Kahramanmaras Sutcu Imam Universitesi Ziraat Fakultesi Biyosistem Muhendisligi Bolumu laboratuvarinda yurutulen calismada, Kahramanmaras bolgesinde sulamada yaygin olarak kullanilan 4 farkli firmaya ait damla sulama laterallerinin 7 farkli basinc altinda (0.5, 0.75, 1.00, 1.25, 1.50, 1.75 ve 2.00 atm) gostermis olduklari damlatici akis ozellikleri, basinc-debi iliskisi, yapim farklilik katsayisi (CV), damla turdesligi (EU), sulama suyu es dagilim katsayisi (CU) ve istatistiksel uniformite (Us) degerlerinin uygunlugu Amerika Ziraat Muhendisligi Odasi (ASAE) standartlarina gore incelenmistir. Calisma sonucunda; damlaticilarin artan basinc degerlerinde debi degerlerinin de arttigi gorulmustur. Firmalarin 1 atmosfer basinc altinda vermis olduklari 4 lsa -1 ’lik debi degerlerinde A firmasinda % 1, B firmasinda % 15.5, C firmasinda % 1.5 ve D firmasinda % 12.5’luk bir farkliligin oldugu belirlenmistir. Ayrica, yapim farklilik katsayisi, damlatici turdesligi, turdeslik katsayisi ve istatistiksel uniformite degerlerinin standartlara uydugu, siniflama degeri olarak cok iyi ve iyi degerlerin aldigi gorulmustur.

As a result of this study, it was determined that the responses of the drippers with flow rate values with 4 l h -1 under pressure of 1.00 atmosphere differs from each other in the ratios as follows: A firm in % 1, B firm in 15.5 %, C firm in 1.5 % and, D firm in 12.5 %. In addition, variation coefficient, dripper uniformity, uniformity coefficient and statistical uniformity values meet the standards, and revealed good and very good values as descriptive data.
