Abstract: A field experiment was conducted during three consecutive rabi seasons of 2015-16, 2016-17 and 2017-18 at research farm of Rajasthan Agricultural Research Institute, Durgapura, Jaipur on a sandy loam soil to identify the suitable row ratios of chickpea and linseed under intercropping situation and their effect on productivity and profitability. The present experiment comprising eight treatments viz sole crops of chickpea and linseed and six intercropping systems of chickpea + linseed in 3:1, 4:1, 5:1, 3:2, 4:2, 5:2 row ratio. The results revealed that maximum pooled chickpea equivalent yield (2072 kg ha-1), mean gross return (Rs.109934), net return (Rs. 82404) and B:C ratio (3.40) and LER (1.17) was recorded under chickpea +linseed in 5:1 row ratio. The pooled mean increases in chickpea equivalent yield due to 5:1 row ratio and 5:2 row ratio were 15.95 and 21.03 percent and 12.93 and 17.87per cent, respectively over sole chickpea and sole linseed .The least pod damage (13.94 %) was observed in 3:2 row ratio which was statistically at par with 4:2, 5:2 and these were significantly superior over row ratios of 3:1, 4:1, 5:1 and sole chickpea.
