15 صفحه اولCxciii. the Composition of Forage Crops
MANY papers dealing with the composition and digestibility of forage crops are to be found in the literature, but the analyses are usually restricted to those few groups included in the conventional methods of agricultural analysis. These rarely extend beyond the determination of ash, or mineral constituents, crude protein, crude fibre and ether-soluble material. The sum of these analyses is fa...
متن کاملThe Future of Alfalfa and Forage Crops
A diversity of forage species and forage ecosystems suited to different management practices exists in the United States. The future of cultivar development in forages includes the new and evolving areas of genomic and transgenic technologies. Genomic research gained momentum with the publication of the complete DNA sequence of the human genome and has since expanded to plant species including ...
متن کاملConservation Tillage Corn and Forage Crops
Several reduced, or conservation tillage (CT) approaches are currently being evaluated in Central Valley forage production systems. In theory, these practices reduce costs and minimize the time needed to go from one crop to the next. Recent single-year trials with dairy forage producers in Stanislaus and Tulare Counties have evaluated the potential of several CT systems and have identified a nu...
