Declining water resources is a major concern in the Southern High Plains of New Mexico and Texas, where dairy and beef industry is growing rapidly. To sustain the animal industry in the region, we need to improve efficiency of using limited water resources. One of the ways of achieving it is by developing intercropping systems of sorghum (Sorghum bicolor L) and legume crops, which in addition to increasing water use efficiency, increases quality of the forage. A field research was initiated in 2006 to identify a suitable legume crop for intercropping with forage sorghum. Of 10 different legumes tried, lab lab cv. Rongai (Lablab perureus L) was the most promising. Irrigation levels seem to influence the contribution from legume. Most of the prostrate legumes did not perform well. Shade tolerance and growth duration closely matching forage sorghum are two important factors in deciding ideal intercrop with sorghum.
