A field experiment was conducted during 2000-02 at the Indian Agricultural Research Institute, New Delhi, India to find out the optimum irrigation schedule for gram (Cicer arietinum cv. Pusa 256) + Indian mustard (Brassica juncea cv. Pusa Jaikisan) intercropping system. Irrigation at 0.2 irrigation water:cumulative pan evaporation (IW:CPE) ratio in sole gram and 0.4 IW:CPE ratio in Indian mustard was optimum for seed yield. Irrigation in gram at 0.4 IW:CPE ratio caused 31.6% reduction in seed yield compared with 0.2 IW:CPE ratio. The yield of gram + Indian mustard in intercropping systems was dependent on row proportions of component crops. Gram-equivalent yield (GEY) was highest in sole Indian mustard (3.04 tonnes/ha) and with irrigation at 0.2 IW:CPE ratio (2.42 tonnes/ha). At closer row proportions (2:1 and 3:1) of gram and Indian mustard intercropping system, irrigation at 0.4 IW:CPE ratio recorded higher gram-equivalent yield (2.88 and 2.744 tonnes/ha), while at wider row proportions (4:1 and 6:1) irrigation at 0.2 IW:CPE ratio gave higher gram-equivalent yield (2.41 and 2.33 tonnes/ha). The water-use efficiency (kg/ha-mm) was highest in sole Indian mustard (12.66) and unirrigated crops (11.7).
