Determining Interest in Value-added Planters: Consumer Preference and Current Grower and Retailer Perceptions

Autor: Kathleen M. Kelley, E. Jay Holcomb, Jonathan Phillips

Publikováno v: HortTechnology. 17:238-246

Three intercept surveys were conducted at the Southeast Research and Extension Center in Landisville, Pa., at three separate field days during the period of 28 July to 4 Aug. 2004 to determine grower (n = 78), retailer/landscaper (n = 52), and consum

Autor: Bruce Dye, Lisa White, Eric P. Burkhart, Michael D. Orzolek, Kathy Demchak, E. Jay Holcomb, William J. Lamont

Publikováno v: HortTechnology. 13:358-362

At the Pennsylvania State University (Penn State) High Tunnel Research and Education Facility, a system of production of high-value horticultural crops in high tunnels has been developed that uses plastic mulch and drip irrigation. The Penn State sys

Greenhouse Growth of Marigolds in Three Leached Sources of Spent Mushroom Compost over a 3-Year Period

Autor: E. Jay Holcomb, Charles W. Heuser, John R. Young

Publikováno v: HortTechnology. 12:701-705

Though high electrical conductivity (EC) levels are commonly held to be the primary limiting factor for using spent mushroom compost (SMC) as a growing substrate, EC can be reduced by leaching. This allowed SMC to be successfully used for growing pla

In situ determination of electrical conductivity of potting media using time domain reflectometry

Autor: James M. Hamlett, E. Jay Holcomb, Tom O. Owino

Publikováno v: Communications in Soil Science and Plant Analysis. 31:2685-2705

The possibility of measuring both the volumetric water content (ν θ) and bulk electrical conductivity (ECb) of media using a single instrument makes time domain reflectometry (TDR) invaluable for greenhouse potting media ν and ECb determination. L

Marigold Growth and Phosphorus Leaching in a Soilless Medium Amended with Phosphorus-charged Alumina

Autor: E. Jay Holcomb, Yuan Ling P. Lin, Jonathan P. Lynch

Publikováno v: HortScience. 31:94-98

Alumina granules charged with P were used as an amendment to improve the ability of a soilless medium to retain P and provide it to plants. Commercially available alumina was acidified, saturated with P, and evenly distributed in a medium of peat, ve

Chrysanthemum and poinsettia growth in coal gasification slag amended media

Autor: Paul N. Walker, E. Jay Holcomb

Publikováno v: Communications in Soil Science and Plant Analysis. 26:2497-2510

Coal gasification slag is a by‐product of the power industry that may prove useful to the horticultural industry as a component of growing media. The objectives of this research are to determine if suitable crops of chrysanthemum and poinsettia can

Growth of bedding plants and poinsettias in mineral wool and mineral wool/peat substrates

Autor: Thomas M. Contrisciano, E. Jay Holcomb

Publikováno v: Communications in Soil Science and Plant Analysis. 26:485-501

Studies were conducted to ascertain the suitability of mineral wool (MW), either alone or in combination with sphagnum peat moss, as a substrate for potted greenhouse plants. Two types of hydrophyllic mineral wools, cleaned mineral wool (CMW) and unc

A practical method for the production of flowering Easter lilies from callus cultures

Autor: Enaksha R. M. Wickremesinhe, Richard N. Arteca, E. Jay Holcomb

Publikováno v: Scientia Horticulturae. 60:143-152

Callus cultures were established from immature leaf explants of Easter lily ( Lilium longiflorum Thunb. cv. ‘Nellie White’). These callus cultures were induced to undergo organogenesis within 3 weeks upon subculture to medium containing 0.1 mg l
