The effects of different fertigation equipments used in drip irrigation and deficit irrigation applications on tomato

This study was carried out to determine the effects of fertigation equipments under deficit irrigation conditions on tomato plant in the experiment fields of Alata Horticultural Research Station, Tarsus Soil and Water Resources Location during 2014-2015. In the study F1 injection pump, F2 venturi injector and F3 pressure diversity treatments are in main plots, I100 full irrigation and I70 – I50 deficit irrigation treatments as the sub-main plots were created. The experiment was carried out in randomized block in split-split plot design with three replications. The highest tomato yield was obtained 4875 kg da-1 in 2014 and 5106 kg da-1 in 2015. According the other two fertigation treatments, F1 injection pump transmitted all fertilizer concentrate to crop roots during irrigation while F2 venturi injector couldn't transmit all fertilizer amount. It is determined that the highest yield and other quality parameters were in I100 full irrigation treatments.
