, marigold ( Tagetes erecta Big. ‘Inca Gold’) grown in a 3 pine chips:1 pinebark (by volume) substrate were equal to those grown in a 100% pinebark substrate when additional nutrients were applied to pine chip substrate. More recently, Boyer et al. (2006a

quantification procedure. z A plant species that may not benefit from supplemental silicon-based fertilizer applications is marigold. Frantz et al. (2008) reported that ‘African Atlantis Primrose’ marigold, Tagetes erecta L. plants, which received a nutrient

marigold ( Tagetes erecta ), Cox (1993) reported that single CRF applications of the total crop N at planting resulted in more nitrate leaching by the end of the crop cycle relative to SF applications. These losses likely resulted in the provision of more

43 mol·m −2 ·d −1 . They found that only one, african marigold ( Tagetes erecta ‘American Antigua Orange’), showed an increase in height with more light through all DLIs examined. Both ageratum ( Ageratum houstonianaum ‘Hawaii White’) and petunia

’ flower number was highest at a DLI of 19 mol·m −2 ·d −1 or higher, whereas Catharanthus roseus L. ‘Pacific Lilac’, Petunia × hybrida ‘Apple Blossom’, Tagetes erecta L. ‘American Antigua Orange’, and Zinnia elegans L. ‘Dreamland Rose’ flower

more recent alternative substrate similar to sawdust was described by Wright and Browder (2005) . They demonstrated that Japanese holly ( Ilex crenata ‘Chesapeake’), azalea ( Rhododendron obtusum ‘Karen’), and marigold ( Tagetes erecta ‘Inca Gold

Sally’ salvia, ‘Bonanza Yellow’ marigold ( Tagetes erecta ), and ‘Cooler Pink’ vinca ( Catharanthus roseus ] increased as N fertilizer rate increased from 0 to 2 lb/1000 ft 2 N per year; but, the authors reported no effect of N rate on aesthetic quality

active endogenous gibberellins by PGRs can reduce plant height. Paclobutrazol effectively inhibits elongation of several floriculture crops, including seed impatiens ( Impatiens walleriana ), salvia ( Salvia splendens ), marigold ( Tagetes erecta
