Abstract A field experiment was conducted during winter seasons of 2005–06 and 2006–07 at Shalimar, Srinagar to study the productivity and profitability of lentil (Lens Culinaris Medik)–based intercropping systems. Eleven lentil based cropping systems viz., lentil sole, brown sarson (Brassica campestris L. var. brown sarson) sole, oats (Avena sativa L.) sole, lentil+brown sarson 1:1, lentil+brown sarson 2:1, lentil+brown sarson 4:1, lentil+brown sarson 6:1, lentil+oats 1:1, lentil+oats 2:1, lentil+oats 4:1 and lentil+oats 6:1, were tested in randomized block design with three replications. Number of pods/plant of lentil were significantly higher in sole crop followed by 6:1 and 4:1 row ratio of lentil + brown sarson and lentil + oats systems, respectively. Significantly higher siliquae/plant was recorded in intercropping systems compared to sole brown sarson. Seed yield of lentil (1.46 t/ha) and brown sarson (1.37 t/ha) was highest in sole stand. Based on lentil seed equivalent yields (1.47 t/ha), net returns (Rs 25,750) and B:C ratio (3.32), lentil + oats in 2:1 was found the best. It was closely followed by sole lentil.
