more economical than nursery stock transplantation
<br />techniques to meet the shrub density standard. The
<br />economic comparisons shown indicate that great
<br />advances in transplant technology would be necessary to
<br />overcome the huge differences in shrub establishment
<br />costs between transplantation and direct seeding and
<br />these authors believe that research and technology
<br />development should be concentrated in the area of direct
<br />seeding and enhanced, good quality, seed production.
