Abstract

In field trials at Rajendranagar in 1983-84, groundnuts cv. Robout 33-1 and pigeonpeas cv. ICPL-6 were grown in pure stands with 30 and 60 cm between-row spacing, resp., or intercropped in a 3, 4, 5, 6 or 8:1, groundnut rows:pigeonpea rows ratio with 30 cm between row spacing. Within row spacing was adjusted accordingly to maintain pure stand and intercrop groundnut and soyabean plant densities of 333 000 and 60 000 plants/ha, resp. Av. groundnut pod yield ranged from 558 kg/ha (3:1 groundnuts:pigeonpeas intercrop) to 1720 kg (pure stand). Av. pigeonpea grain yield ranged from 1048 kg (8:1 intercrop) to 1619 kg/ha (3:1 intercrop); pure stand yield was 1339 kg/ha. Mean land equivalent ratios were 1.15, 1.36, 1.49, 1.48 and 1.41 for the 3:1, 4:1, 5:1, 6:1 and 8:1 ratios of groundnut rows:pigeonpea rows, resp. The economic returns from the different sowing arrangements are considered.
