A field experiment was conducted to evaluate the effect of spacing and phosphorus on nodulation, yield and quality of broad bean under late sown rainfed condition of Manipur during the rabi seasons of 2002–03 and 2003–04. On the basis of two years results the highest nodulation, seed yield and crude protein content was associated with the application of 60 kg P₂O₅/ha which was significantly superior to all the other levels of phosphorus except for the crude protein content which remained on par to 40 kg P₂O₅/ha. Though significantly higher nodulation and crude protein content of the seed was recorded in wider spacing of 40 × 10cm, however, the highest seed and stover yield were recorded in the closer spacing of 20 × 10 cm.
