Effect of irrigation and phosphorus fertilization on growth, yield and nodulation of broad bean (Viciafaba L.)

A field experiment was carried out during rabi seasons of 2009–10 and 2010–11 to study the effect of irrigation and phosphorus levels on growth, yield and nodulation of broad bean. Treatment receiving irrigation at \|/=-0.03 MPa at 30 cm soil depth (I₃) maintained its superiority with 5.11 and 34.97% higher seed yield compared to irrigation at \|/=-0.05 MPa at 30 cm soil depth (I₂) and rainfed (I1), respectively. Treatment receiving 75 kg P₂O₅ ha⁻¹ (P4) was significantly superior with 9.26 and 28.26% higher seed yield over 50 kg P₂O₅ ha⁻¹ (P₃) and 25 kg P₂O₅ ha⁻¹ (P₂) treatments, respectively. Growth, yield attributing characters and nodulation also followed the trend of seed yield. The treatment combination receiving irrigation at =-0.03 MPa at 30 cm soil depth along with 75 kg P₂O₅ ha⁻¹ (I3P4) proved as best treatment combination.
