A field experiment was conducted during summer season 2013 at AL-Anbar Governorate to study the response of peanut (Arachis hypogea L.) to different concentrations and types of boron under deficit irrigation conditions. A split-split plot design was laid out in three replications. Three concentrations of boron (0، 150، and 300) mg/l were sprayed. The experiment also included three levels of irrigation (50, 75 and 100) % of depth of irrigation. The results showed that the concentration of 150 mg/l of sprayed boron caused an increase in dry root and plant weight, pod yield and dressing ratio (12.50 g/plant, 380.96 g/plant,320.08 g/plant, %74.9 and 1.170 Kg/m3 respectively. The level of 75% of depth of irrigation gave best indicators for both dry root and plant weight, pod yield and dressing ratio (48.17 cm, 14.83 g/plant, 452.23 g/plant, 357.25 g/plant and 87.6% respectively. The results also showed that the effect of triple interaction between types and concentrations of boron and levels of irrigation was insignificant for most of the traits except dry plant weight.
