摘要：Figures See all figures Authors Jérôme Bossuet , Vincent Vadez ICRISAT Patancheru 502324 Andhra Pradesh India Key words: crop systems, grain legumes, nutrition value, soil fertility, sustainable intensification DOI : 10.1684/sec.2014.0408 Page(s) : 314-21 Published in: 2013 Nitrogen and phosphorus are two of the main nutrients for agriculture but their growing scarcity makes them increasingly less available and affordable for farmers in the semi-arid tropics. Legumes have the comparative advantage over other plant species of being able to independently fix nitrogen, but also to absorb natural phosphorus that is in non-soluble form in the soil. In addition to soil fertility, grain legumes bring other important benefits for farmers in different farming systems. It is a quality fodder source for livestock. Rich in protein, energy and sometimes in lipids, grain legumes are nutritious food for humans. They are ideal as rotation crops with cereals and have also become a cash crop in some regions. Legumes should play an important role in future crop systems in semi-arid tropics. This article discuss the importance legumes, in particular grain legumes, could have as fertilizing and nutritious crops for farmers in semi-arid tropics if the current constraints for large-scale cultivation can be addressed.
