RT Journal Article SR Electronic T1 Early field performance of Acacia koa seedlings grown under subirrigation and overhead irrigation JF Native Plants Journal JO NATIVE PLANTS JOURNAL FD University of Wisconsin Press SP 94 OP 99 DO 10.3368/npj.12.2.94 VO 12 IS 2 A1 Davis, Anthony S A1 Pinto, Jeremiah R A1 Jacobs, Douglass F YR 2011 UL http://npj.uwpress.org/content/12/2/94.abstract AB Koa (Acacia koa A. Gray [Fabaceae]) seedlings were grown with subirrigation and overhead irrigation systems in an effort to characterize post-nursery field performance. One year following outplanting, we found no differences in seedling height or survival, but root-collar diameter was significantly larger for subirrigated seedlings. This indicates that koa seedlings, with equal or better morphological quality compared with overhead irrigated seedlings, can be effectively produced using subirrigation systems, thus allowing for potential reductions in water use and wastewater during nursery culture.
