Selection of sorghum (Sorghum bicolor) and millet (Pennisetum americanum) cultivars by production efficiency and forage quality indexes.

Sumario: Six commercialvarieties of sorghum (Sorghum bicolor), one of pearl millet(Pennisetum americanum), and six millet lines from TheInternational Crop Research Institute for the SemiaridTropics (ICRISAT), Hyderabad, India, were planted onMarch 23, 1998 in Santa Cruz Xoxocotlán, Oax., México, toidentify materials of sorghum and millet with higherproduction efficiency and forage quality under conditions ofrestricted irrigation, as a result of generalized lower watertable levels during the spring-summer period. To facilitate theselection of varieties, productivity and modified qualityindexes were generated from dry matter production data. TheIPM was more adequate than the IP to discriminate thevarieties for their forage production efficiency and quality.On average, the sorghum genotypes, especially Sweet Siouxand Domor, the last one showing little variation betweenharvests, were more efficient in dry matter production thanthe millet ones. However, because of their high productionefficiency and quality at the first harvest, the millet cultivarsNELC C4 and ICMH 423 could be recommended for farmerswhich need forage urgently and have less water availability.
