Abstract
The emergence of direct seeded vegetables can be
reduced by numerous environmental and physical stresses
which commonly occur at the time of sowing in Florida. Tem
perature extremes, heavy rainfall, drought, and soil compac
tion can greatly alter total plant stands and seedling unifor
mity. A number of seed priming treatments improved germi
nation and emergence of cabbage (Brassica oleracea L), car
rot ( Daucus earota L), celery (Apium graveolens L), tomato
(Lycopersicon esculentum Mill.), pepper (Capsicum annuum
L), and lettuce (Lactuea sativa L). An additional improve
ment in stand uniformity for a number of crops was obtained
when seeds were sown with soil amendments. Use of the
gel-mix (peat:vermiculite:gel combination) and/or calcined
clay amendments (GrowSorb) greatly improved emergence
and plant uniformity in pepper, tomato, cabbage, and lettuce
sown under temperature stress.
