Keeping in view the emerging dryland farming systems for the semi-arid tropics, an attempt has been made to design and develop appropriate intercropping systems that reflect transgressive yielding, stability and profitability. Studies on competition between species enable characterization of complementary, aggressive and relatively neutral species. Under competition stress sorghum (Sorghum bicolor) was the most stable species, followed by pigeon pea (Cajanus cajan), while groundnut (Arachis hypogaea) has been found to be the most sensitive. Apart from yield, prevailing prices also become an important factor in the choice of component crops. In 7 of the most profitable intercropping systems identified, sorghum was a constant component
