Abstract

Greenhouse and field tests were made to evaluate the
frost protection afforded by various seedbed designs.
Planting in pockets was the most effective in reducing
radiative freeze damage to sugar beet (Beta vulgaris)
seedlings in the two-leaf stage. Pockets were 7.5 cm in
diameter by 5 cm deep, formed at 45° to the horizon in
45° south-facing slopes on sides of 20-cm-high soil ridges.
During freeze periods, leaf temperatures of the plants in
the pockets averaged 3.4 C and 2.2 C higher than leaf
temperatures of plants in the conventional seedbed under
greenhouse and field conditions, respectively. Temperature
differences were not as great under field conditions
because of low soil temperatures. The planting system
could, however, add 2 weeks to the spring growing season
for sugar beets in southern Idaho, provided soil temperatures
are high enough for germination.
