The field experiment was conducted under rainfed condition at Central Research Station of BARl, Joydebpur, Gazipur during rabi seasons, 1993-94 and 1994-95, respectively. The soil was acidic with pH 6.5 and silty clay in texture. The experiment was laid out in randomized block design with three replications. The unit plot size was 5m 3m. The treatments comprised : Tl) Sole chickpea, T2) Sole mustard, T3) Sole barley, T4) Sole coriander T5) Chickpea (75%) + mustard (25%), T6) Chickpea (75%) + barley (25%), T7) Chickpea (75%) + coriander (25%), T8) Chickpea (50%) + mustard (50%), T9) Chickpea (50%) + barley (50%), TlO) Chickpea (50%) + coriander (50%), Tll) Chickpea (100%) + mustard (33%), Tl2) Chickpea (100%) + barley (33%) and Tl3) Chickpea (100'%) + coriander (33%). Sole chickpea and mixed crops were fertilized on the basis of sole chickpea dose (20-40-20 N P205 K20 kg/ha) but sole mustard, barley and coriander were fertilized with their recommended doses. In mixed cropping treatments seed of both the crops were mixed before sowing in proportion of recommended seed rate of each crop. The crop was sown on 15 November, 1993 and 10 November, 1994. The seed rates of sole chickpea, mustard, barley and coriander were 30, 8, 100 and 10 kg/ha, respectively. The recommended varieties of different crops were Nabin, Tori - 7, conquest and local for chickpea, mustard, barley and coriander respectively. All fertilizers (urea, TSP and MP) were given as basal. Intercultural operations were done as and when necessary. The chickpea, mustard, barley and coriander were harvested on 12 March, 6 February, 27 March in 1994 and 21 March, 30 January, 15 March and 1 March in 1995, respectively. The amount of winter rains recorded during November, December, January, February and March were 1.6, 0.0, 0.0, 0.0 and' 73.2 mm during 1993-94 and 0.0,0.0,0.0,17.8 and 84.4 mm during 1994- 95, respectively distributed over 6 and 12 rainy days. The initial soil moisture (at sowing) was 19.5 to 24% at 0-15 to 45-60 em soil depth. Equivalent yield was converted on the basis of prevailing market prices of different commodities used for computation of economics of different treatments.
