The present study investigates the commercial potential of speciality corn (sweet corn and baby corn), groundnut, and parching sorghum in pigeonpeabased intercropping systems in Odisha. Pulses are soil-enriching crops, and conversely, corn and parching sorghum are exhaustive, but have much higher economic potential. A combination of both may be a sustainably profitable enterprise for small and marginal farmers. The intercropping of pigeonpea with baby corn in 1:2 proportion (replacement series) gave the maximum system pigeonpea equivalent yield (2461 kg/ha), closely followed by pigeonpea+groundnut in a 1:2 proportion (additive series), which gave PEY of 2448 kg/ha. However, maximum net return (Rs. 97,176/-) and B:C ratio (2.49) was recorded from pigeonpea+groundnut intercropping system. The maximum system Land Equivalent Ratio (LER=1.64) was recorded with the pigeonpea+groundnut intercropping system. This treatment also recorded the maximum monetary advantage index (Rs. 63,366/-). Pigeonpea recorded maximum competition ratio (2.49), Aggressivity (1.66), and relative crowding coefficient (20.63) when intercropped with groundnut. Pigeonpea was found as the dominant component, and intercrops are dominated through all intercropping combinations. However, pigeonpea+ groundnut (1:2) and pigeonpea+baby corn (1:2) intercropping are recommended for the farmers of the East and south eastern coatal plain agroclimatic zone of Odisha for higher profitability, depending on market demand.
