In Ethiopia, the use of traditional and improved grain sorghum [Sorghum bicolor (L.) Moench] variety as green forage crop is limited mainly by large stalk thickness low nutritive values. An experiment was conducted to explore if biomass accumulation values could be managed seeding rates. Two dual-purpose varieties (Melkam Chelenko), one local (Masugi) each representing early late maturity group...

A two-year field experiment was conducted to investigate the potential application of soil electrical conductivity for variable rate seeding. Map calculations and geo-statistical techniques were used to establish a relationship among EC, elevation, seeding rate, and yield. Yield data taken from the first year, which was a dry year, showed inconsistent relationships and the overall yield variati...
