Recent droughts and subsequent reduction of water resources in arid and semi-arid regions have highlighted the necessity of altering surface irrigation techniques to modern methods of irrigation. The present study compares drip irrigation tubes with 60 and 75 cm spacing with the furrow irrigation prevalent in Hamedan province, Iran and investigates the effects of the former form of irrigation on the productivity of wheat crops with various cropping layouts. This experiment was implemented as a field-scale experiment in sandy clay loam texture soil and consisted of the following treatments: 4 cultivated rows with 15 cm spacing on both sides of the drip tape, and 75 cm spacing between tapes (T1); 4 cultivated rows with 20-cm row spacing, and 75 cm drip tape spacing (T2); 3 cultivated rows with 20 cm row spacing and 60-cm drip tape spacing (T3); 4 cultivated rows with 15 cm row spacing and 60 cm drip tape spacing (T4); 2 cultivated rows with 30 cm row spacing and 60 cm drip tape spacing (T5); and furrow irrigation which consisted of 4 cultivated rows with 12 cm spacing on the ridge and 60 cm furrow spacing (F). The results showed that the maximum and minimum value of the two-year average grain yield and irrigation water productivity were those of T1 and F treatments at 7443 and 5996 kg ha⁻¹ and 1.91 and 1.02 kg m⁻³, respectively. The maximum and minimum values of two-year average weight of 1000 kernels were also obtained from T1 and F treatments at 44.3 and 42.1 g, respectively. The mean irrigation water productivity obtained for drip and furrow irrigation treatments were 1.74 and 1.01 kg m⁻³, respectively. Results indicated that drip irrigation caused a 33% reduction in applied irrigation water use and a 72% increase in irrigation water productivity in comparison to the furrow irrigation method.

干旱和半干旱地区最近的干旱和随之而来的水资源减少，突显了将地表灌溉技术改为现代灌溉方法的必要性。本研究将间隔为60和75厘米的滴灌管与伊朗哈马丹省普遍使用的沟灌进行了比较，并研究了前一种灌溉方式对不同种植布局的小麦作物的生产力的影响。该实验是在砂质壤土质地土壤上进行的田间规模实验，包括以下处理：4个耕作行，滴水带的两侧间距为15 cm，带之间的间距为75 cm（T1）；4行耕作，行距为20厘米，滴灌带间距为75厘米（T2）；3行耕种，行间距为20厘米，滴灌带间距为60厘米（T3）；4个耕作行，行间距为15厘​​米，滴灌带间距为60厘米（T4）；2行，行距为30厘米，滴灌带间距为60厘米（T5）；犁沟灌溉由4行耕作组成，行距为12厘米，垄距为60厘米（F）。结果表明，两年平均粮食产量和灌溉水生产率的最大值和最小值分别为7443和5996 kg·ha的T1和F处理。^-1和1.91和1.02 kg m ^-3。从T1和F处理分别获得了44.3 g和42.1 g的1000粒玉米的两年平均重量的最大值和最小值。滴灌和沟灌的平均灌溉水生产率分别为1.74和1.01 kg m ^-3。结果表明，与沟灌法相比，滴灌法减少了33％的灌溉用水量和72％的灌溉水生产率。
