Rendimiento por hectárea de sorgo grano y de fríjol en México: riego vs temporal

In Mexico, the production of grain sorghum and bean in irrigation districts in 2014, consumed the equivalent of 85.45% of water intended for the urban public use in all over the country. The aim of this research was to test whether the performance of tons per hectare of the mentioned crops produced in irrigation districts is higher -up to 3.3 times, as affirmed- than the obtained under rainfed conditions. The testing was carried out based on an analysis of variance of the average performance in tons per hectare of both obtained products in irrigation districts and rainfed at the national level; for this was used information grouped by irrigation districts of the crop years from 2001-2002 to 2013-2014. It was concluded that in each one of the considered crop years, the average performance per hectare of beans and grain sorghum obtained in rainfed was equal to the obtained in irrigation districts, with a significance level of 95%.
