Abstract

A substrate component (WholeTree) made from loblolly pine (Pinus taeda L.) was evaluated along with starter fertilizer rate in the production of greenhouse-grown petunia (Petunia xhybrida Vilm. 'Dreams Purple') and marigold (Tagetes patula L. 'Hero Spry'). Loblolly pine from a 12-year-old plantation were harvested at ground level, chipped, and further processed through a hammer mill to pass a 0.64-cm screen. The resulting WholeTree (WT) substrate was used alone or combined with 20% (WTP2) or 50% (WTP5) (by volume) Canadian sphagnum peatmoss and compared with an industry standard peat-lite (PL) mix of 8 peatmoss : 1 vermiculite : 1 perlite (by volume). Substrates were amended with 1.78 kg.m-3 dolomitic lime, 0.59 kg.m-3 gypsum [CaSO4-2(H20)], 0.44 kg.m-3 Micromax, 1.78 kg.m-3 16N-2.6P-9.9K (3- to 4-month release), and 1.78 kg.m-3 16N-2.6P-10.8K (5- to 6-month release). A 7N-I.3P-8.3K starter fertilizer (SF) was added to each substrate at 0.0, 1.19, 2.37, or 3.56 kg.m-3. Container capacity (CC) was greatest for PL and decreased as the percentage of peatmoss in the substrate decreased with WT having 35% less CC than PL. Conversely, air space (AS) was greatest for the WT and decreased as percentage of peatmoss increased with PL containing 33% less AS than WT. In general, petunia dry weight was greatest for any substrate containing peatmoss with a SF rate of 2.37 kg.m-3 or greater. The exception was that petunia grown in WT at 3.56 kg.m-3 SF had similar dry weight as all other treatments. Marigold dry weight was similar for all substrates where at least 2.37 kg.m-3 SF was used.

50. Milled Paulownia tomentosa as a Substrate Component in Greenhouse Annual Production©.

Author

Weldon, Tyler L., Fain, Glenn B., Sibley, Jeff L., Gilliam, Charles H., and Witcher, Anthony L.

Abstract

The article presents a study which examines the potential of milled Paulownia tomentosa (PT) as substrate in greenhouse annual production at the Paterson Greenhouse Complex in Auburn University in Alabama. The study combined PT substrate component with different rates of Canadian sphagnum peatmoss (P) to achieve six treatments for container-grown petunia or dianthus. The study found the influence of PT-amended substrates in the reductions of plant growth.
