Selection of sorghum (Sorghum bicolor) and millet (Pennisetum americanum) cultivars by production efficiency and forage quality indexes.
varieties of sorghum (Sorghum bicolor), one of pearl millet
(Pennisetum americanum), and six millet lines from The
International Crop Research Institute for the Semiarid
Tropics (ICRISAT), Hyderabad, India, were planted on
March 23, 1998 in Santa Cruz Xoxocotlán, Oax., México, to
identify materials of sorghum and millet with higher
production efficiency and forage quality under conditions of
restricted irrigation, as a result of generalized lower water
table levels during the spring-summer period. To facilitate the
selection of varieties, productivity and modified quality
indexes were generated from dry matter production data. The
IPM was more adequate than the IP to discriminate the
varieties for their forage production efficiency and quality.
On average, the sorghum genotypes, especially Sweet Sioux
and Domor, the last one showing little variation between
harvests, were more efficient in dry matter production than
the millet ones. However, because of their high production
efficiency and quality at the first harvest, the millet cultivars
NELC C4 and ICMH 423 could be recommended for farmers
which need forage urgently and have less water availability.
