Response of grass pea (Lathyrus sativus L.) to row spacing and levels of phosphorus levels under rainfed conditions of Manipur. Agricultural Science Digest. 38(2): 131-134. doi: 10.18805/ag.D-4579.
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 (20 cm x 10 cm and 30 cm x 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 x 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 x 10 cm) probably due to greater plant population in per unit area.
