Abstract: The present investigation was undertaken at Pulses and Oilseeds Research Sub-station, Beldanga, Murshidabad, West Bengal for two consecutive rabi seasons to evaluate different levels of seed priming (no soaking, water soaking, 2% KH2PO4 solution and sprouted seeds) along with varying levels of foliar nutrition (no spray, water spray, 2% urea spray, 2% DAP spray and 2% KCl spray) using lathyrus variety Ratan (BioL 212). It was found that use of sprouted seeds significantly recorded the highest seed yield (1021.77 kg ha-1). Next in order was seed soaking in 2% KH PO solution (964.67 kg ha-1). Among foliar treatments, 2% urea spray could significantly produce the highest seed yield (1040.00 kg ha-1) and was closely followed by 2% DAP spray (983.75 kg ha-1). The study indicated that sowing of either sprouted or 2% KH PO soaked seeds followed by foliar spray of 2% urea or 2% DAP solution (twice) at pre-flowering stage and 10 days thereafter proved to be effective in improving growth and productivity of lathyrus in rice-utera system...
