Cxciii. 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 کاملEvaluation of Cross-fertilization in Forage Crops
In the improvement of forage crop varieties knowledge of~e .extent of cross-fertilization is of value for (1) de~g the extent and randomness of crossing in breedmg procedures, (2) estimating varietal changes due to contamination and mechanical mixtures, and (3) evaluating effects of cross,fertilization in the development and production of synthetic and hybrid combinations. Genetic markers can a...
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...
متن کاملSilage from tropical cereals and forage crops
The preservation of forages by ensiling has been a well known technology for many years and is popular in North America and Europe. This technology requires high investment in facilities, accurate timing in the several stages of the ensiling process, and better understanding of the whole process than hay making demands. In addition to these demands, silage making and management in tropical cond...
