Description
700,000 ha of the temperate semi-arid area of Zacatecas state are grown with rainfed crops. Low productivity is obtained from these crops: 350 kg/ha of beans grain and 500 kg/ha of corn grain. This state is characterized by a wide range of topographic and climatic values. A need for alternative crops led to establishment of a trial to evaluate rainfed forages, and to know in what range these could be located. Geographic information systems were used to find out the potential area of the species. Results indicated that sorghum presented a higher yield (5822 kgDM/ha) than sorghum x sudan (5460), pearl millet (4316), corn (3783), barley (3092), triticale (2638), wheat (2540), oats (1934) and beans (1243). Pearl millet presented the highest CP (16.5%) and lowest FAD (28.2%); and sorghum x sudan the lowest CP (6.5%) and highest FAD (38.7%). Sorghum (Sucro) produced 2.07 kg DM per each cubic meter of water evapotranspired, and for beans 0.5 kgDM/m3. Areas of low productivity potential for the traditional crop (beans) appeared as the medium potential areas for sorghum forage.
