Özet

A 2-year field experiment was carried out to assess the effects of various rotational systems on crop yield, crop water use (CWU) and water use efficiency (WUE) in a semi-arid region of Central Anatolia. Five crops (winter lentil, Lens culinaris L.; chickpea, Cicer arietinum L.; sunflower, Helianthus anuus L.; spring lentil, Lens culinaris L. and winter wheat, Triticum aestivum L.) and fallow were rotated with winter wheat. The experimental set-up involved a rotation of alternative crops (2003-2004) and wheat (2004-2005). Similarly, wheat plots in the 2003-2004 season were then planted with alternative crops in the 20042005 season. This experiment took place during the last 2 years of a 21-year long field experiment. Soil moisture was measured using a soil moisture neutron probe, and then soil water storage (SWS) of the plant root zone was calculated up to the depth of 90 cm using precipitation and evapotranspiration values.
