Abstract: An experiment entitled “Evaluation of bio-intensive complementary cropping systems involving Mustard - Chickpea intercropping in Indo-Gangetic plains” was conducted in the field of Department of Soil Conservation and Water Management, C.S.A. University of Agriculture and Technology Kanpur, during rabi season of 2017-18 and 2018-19. To find out the suitable cropping systems on yield attributes i.e. number of pods plant^-1, number of seeds pod^-1 1000-seed weight, of chickpea crop. The treatments comprised of T₀ - Mustard alone (45 x10cm): Flat bed - Conventional method (Control-1), T₁ - Chickpea alone (30 x 10 cm): Flat bed - Conventional method (Control-2), T₂- Mustard + Chickpea (1:1): Additive series (45x10cm) Mustard+1Row of (Chickpea), T₃ - Sowing of Chickpea on ridges-one row on ridges, T₄ - Sowing of Chickpea + Mustard by skipping 1 row of Chickpea, T₅ - Sowing of Chickpea on narrow bed (45 cm): two rows of Chickpea, T₆ - Sowing of Mustard on narrow bed + Chickpea (one side mustard other side chickpea) and T₇ - Broad bed furrow -105 cm (BBF): 3 rows of Chickpea on BB and 1 row of Mustard in furrow in Randomized plot design with 3 replications. Results obtained in regarded to yields and quality parameters showed that the Component crops seed yield qha^-1 The mustard yield was obtained higher under Mustard alone (45x 10): Flatbed (Control-1) in first year and second year, 15.13 q/ha and 16.61 q/ha with mean 15.87 q/ha followed by Sowing of Chickpea + Mustard by skipping one row of chickpea as well as under intercropping found second highest 10.93 q/ha in first year and 11.79 in second year 11.36 q/ha. However, the seed yield of intercrops chickpea was obtained highest in Sowing of Chickpea on ridges-one row on ridges of 16.05 q/ha in first year and 17.95 q/ha in second year with average of both year 17.00 q/ha followed by Sowing of Chickpea on narrow bed (45cm): Two row of Chickpea 14.65 q/ha during first year and 16.49 q/ha during second year with average of both year 15.57 q/ha respectively. Highest LER recorded in Mustard + Chickpea (1:1): Additive series during both the years followed by Broad bed furrow -105 cm (BBF): 3 rows of Chickpea on BB and one row of Mustard in furrow and Sowing of Chickpea on ridges-one row on ridges produced second highest LER in first year and Broad bed furrow -105 cm (BBF): 3 rows of Chickpea on BB and one row of Mustard in furrow during second year. Showed that protein content in (%) of chickpea seed. Sowing of chickpea on ridges-one row on ridges methods of treatments content maximum protein recorded in first year (21.15) compare to sowing of Chickpea on narrow bed (45cm): Two row of Chickpea (21.03). However lowest protein content recorded in sowing of Chickpea + Mustard by skipping one row of Chickpea as first year (20.71) percent content in chickpea seed during first year. Oil content in (%) of mustard seed. Maximum oil content recorded in Mustard alone (45x 10): Flatbed (Control-1) 40.39% in mustard seed comparison to Sowing of Mustard on narrow bed + Chickpea (one side mustard other side Chickpea) recorded 39.38% in mustard seed. However, lowest oil content recorded in Sowing of Chickpea + Mustard by skipping one row of Chickpea 39.05% oil content in mustard seed during first year experiment.
