Conteúdo: | In new south wales, soybeans are usually grown as a full-season, single crop. Perhaps 10 percent of the area would be double-cropped after awinter cereal grain. The latter system is common in California. Reports indicate that soybeans are also double-cropped before or after winter cereals in central Kansas and following a variety of winter crops inJordan. Although intercropping, particulary with maize, is a common practice in humid regions, there are few references to such patterns under more arid conditions. Similarly, there is little evidence of any established rotations involving soybeans. Attemps to assess the potential of rotations in contributing to the nitrogen supply of the followingcrop have been conducted and are continuing. Soybeans have a higherwater requirement than other summer field crops. Varieties with a shorter a growing season would reduce this requirement and would also allow them to be double-cropped as the second crop with more assurance. Unfortunately, Their photoperiod sensitivity restricts the planting timeand limits the manipulation of season length. Varieties with improved seedling vigor would be valued where the climate and soil conditions, or both, are unfavorable for emergence. Soybeans are grown primarily as a full-season, single crop or under double-cropping where the growing season is long enough to allow the beans to mature. That situation is not likely to change foreseeable future.
