    The effects of fertigation management in the different type of in-line emitters on trickle irrigation system performance
    (2006) Bozkurt, Sefer; Özekici, Bülent
    This study was carried out to determine the effects of different fertigation practices on irrigation system performance in in-line emitters using Samanda? region well water. The experiment was conducted at the research field of the Samanda? Vocational College, University of Mustafa Kemal, Hatay, from 2001 to 2002. In the experiment, three different emitters (1.7, 2.75 and 4.0 L h-1), three different fertilizer treatments (no-fertilizer, hju MKP+Ca(NO3)2+KNO3+ KSO4+NH4NO3 and NH4NO3+KSO4+MKP) combinations with flushing and no flushing management groups were tested in three replications. Emitter discharge rates were tested at the beginning and end of every season to determine emitter flow variations. The effect of the different fertilizer treatments on system performances was found to be statistically significant. Fertilizers which included both calcium and sulfates resulted in lower system performance than the others. Emitters that have the lowest flow rates had the lowest performance. The acid treatment and flushing management increased the system performance slightly, but it was found not to be statistically significant. © 2006 Asian Network for Scientific Information.

    The effects of fertigation managements on clogging of in-line emitters
    (Asian Network for Scientific Information, 2006) Bozkurt, Sefer; Özekici, Bülent
    This study was carried out to determine the effects of different fertigation practices on clogging in in-line emitters using Samanda? region well water. The experiment was conducted at the research field of the Samanda? Vocational College, University of Mustafa Kemal, Hatay, Turkey, from 2001 to 2002. Three different emitters (1.7, 2.75 and 4.0 L h-1) and three different fertigation treatments (no-fertilizer, MKP+Ca(NO3) 2+KNO3+K2SO4+ NH4NO3 and NH4NO3+ K2SO4+MKP) with flushing and no flushing management groups were evaluated in three replications. Emitter discharge rates were tested at the beginning and at the end of every season to determine emitter flow variations which depend on degree of emitter clogging. The effect of the different fertilizer treatments on emitter clogging was found to be statistically significant. Fertilizers which included both calcium and sulfates resulted in higher clogging effects than the others. Emitters that have the lowest flow rates clogged more than the others. The acid treatment and flushing management decreased emitter clogging but it was not found to be statistically significant. © 2006 Asian Network for Scientific Information.
