An experiment was conducted to study the effect of row spacing and phosphorus levels on growth, yield and economics of grass pea (Lathyrus sativus L.) during rabi season of 2011–12 and 2012–13 at the Research Farm, College of Agriculture, Central Agricultural University, Imphal, Manipur, India. The factorial R.B.D. comprised of two spacings (20cm × 10cm and 30cm × 10 cm) and five levels of phosphorus (0, 20, 30, 40 and 50 kg P₂O₅ ha⁻¹) with three replications. Although wider spacing (30 cm × 10 cm) resulted in greater number of pods/plant (12.05) and seeds/pod (4.43) but higher grain yield (739 kg/ha) was recorded with closer spacing (20 cm × 10 cm) probably due to greater plant population in per unit area.
