Sorghum in Brazil.
1978
FERNANDES, F. T. | SCHAFFERT, R. E. | EMBRAPA-CNPMS; ROBERT EUGENE SCHAFFERT, CNPMS.
The area planted to grain sorghum in Brazil has increased since 1970. The major production areas are the states of Rio Grande do Sul and Sao Paulo. Even though the national average yield is 2.5 tonne/ha, results of national trials indicate that this yield can be doubled. The use of sorghum grain in animal feed, at the rate of 8% of the ration, will create a demand of 1 million tonnes of sorghum grown on 400 000 ha by 1980. Recent problems in seed production have restricted the expansion of sorghum. Even though the potential for 1978/1979 is in excess of 1 million ha, the area planted probably will not exceed 200 000 ha due to seed shortages. Forage sorghum is being used in some regions, and sweet sorghum appears to be excellent for the production of alcohol used as a fuel mixture with gasoline. The principal diseases are anthracnose, rust, sorghum downy mildew, and grain "weathering". Sorghum research in Brazil is coordinated by the National Maize and Sorghum Research Center which is a part of the Brazilian Enterprise for Agricultural Research (EMBRAPA). This research is organized in 13 subprojects. In 1977, two grain hybrids, two forage hybrids, and five sweet sorghum varieties with good agronomic characteristics and disease resistance were released to the farmer. Additional hybrids and genetic material will be released in 1979.
