Legumes in current agriculture 2.3. Legumes in current agriculture Figures 1 and 2 show the most important agricultural products in the world, according to the FAO 2007 (Faostat 2008). The correspondent numbers for grain legumes are not quite accurate because of the difficulty to get good statistics. Almost all species that make up this section, particularly in underdeveloped countries (a circumstance that you can also spread to other crops). Therefore, it is possible that a given figure underestimates the total production, but still it is difficult that they could overcome their place. They have, consequently, a large representation to be the only crops bases on its protein content (except soybeans due to the possible consideration of their proteins are byproducts of oil extractions; therefore, there are major pulses in its strict sense). Another consequence that is made out of these figures consist in the interest of modern agriculture that is put in carbohydrates and fats. Considering the soybeans as the only source of protein (in terms of the byproducts oil industry) and beans to feed man based in the Plant Kingdom leaves something to be desired in terms of balance between principle blisters. Although soybeans doubles, at least, the amount of protein produced by grain legumes, it is impossible to think that this contributes to the relative balance of the diet as these, as the soy protein industry a byproduct, is used in developed countries almost exclusively for animal feeding, although numerous derivatives are produced for human food (for burgers, condiments, etc). However, the other major pulse is widely scattered throughout the areas where meat consumption is minimal, justifying the nickname "meat of the poor" as they sometimes are called. In the figure 3 it is possible to observe the data related to the most important species, ordered according to the production in 2007 with a correspondent surface. It is quite easy to check the low yields that are shown by this group species, an index of a primitive agricultural character, which yields have barely increased in the last 30 years (figure 4), keep having almost the constant surface and production. Nonetheless, maintenance does not affect all the countries and all forms of agriculture to the same extent.
