Better production performance of grain legumes can motivate increased cultivation of grain legumes in farming systems currently with and without grain legumes. Due to their inability to compete with other agricultural activities, lentils, faba bean and chickpeas are perceived to have been pushed out of many farming systems. Despite an apparent importance of harvest difficulty in cultivating soybean, the Product Lines do not include efforts to increase the mechanizability due to the availability of private-sector initiatives. Difficulty in harvesting greatly affects three legumes soybeans, faba bean and lentil. Improved traits such as earliness, herbicide-tolerance, and ability for machine harvest can reduce scarce and expensive inputs such as land and labor. For pigeonpea, substantial yield increases are foreseen in the next ten years ranging from 14% in Myanmar (1230 to 1400 kg/ha) to 100% in Mozambique (340 to 700kg/ha). In India, the largest pigeonpea producer, yields are expected to increase 50% (730 to 1100 kg/ha). Such large productivity increases are expected to intensify farming systems where pigeonpea is grown.
