Abstract
Rosmarinus officinalis L. (rosemary) is popular as a culinary herb, landscape plant, and potted florist crop. Little research has been reported on the greenhouse production of this plant. Effects of fertilizer concentration and irrigation rate on root and shoot growth were investigated for R. officinalis ‘Athens Blue Spires’. In the first experiment, rooted cuttings were potted and received fertilizer treatments of 100, 200, or 300 mg‧L nitrogen (N) from 15N2.2P-12.2K water-soluble fertilizer for twelve weeks. Two irrigation regimes were imposed plants were irrigated with fertilizer solution when the growing media dried down to less than 30% or 20% volumetric soil moisture content. Irrigation rate did not affect root growth, but the higher irrigation rate produced larger shoots at all fertilizer concentrations. The largest roots and shoots were produced at the lowest fertilizer concentration. In the second experiment, rooted cuttings of the same cultivar were potted and received fertilizer treatments of 50, 100, 150, or 200 mg‧L N from 15N-2.2P-12.2K water-soluble fertilizer. Plants were irrigated with fertilizer solution when the growing media dried down to less than 40%, 30%, or 20% volumetric soil moisture content. Plants were harvested at two, four, six, or eight weeks. Neither irrigation nor fertilizer affected root or shoot dry weight at week two, six, or eight. Irrigation affected roots at week four with the lowest irrigation rate producing the largest roots at all fertilizer concentrations except 100 mg‧L at the less than 30% irrigation rate. Irrigation also affected shoots at week four with the lowest irrigation rate producing the largest shoots at all fertilizer concentrations except 100 mg‧L at the less than 30% irrigation rate. Our results indicate rosemary can be grown successfully at low fertilizer concentrations and at any of the irrigation rates tested.
