Graph 12.1, below shows growth rates and date to 50% pollen shedding for respective hemp varieties tested in 1996. Four segments of the growth curve summarize the average daily growth rates for the varieties. The earliest variety is Zolotonosha 13 with Unico-B, Irene, Secuieni 1 and Kompolti second, third, fourth and fifth, respectively based on 50% pollen shedding dates. Zolotonosha 13 was the shortest variety. The growth curves reflect this as well.

The rapid growth of hemp and canopy developments is very effective in intercepting light. Hemp was able to intercept 39%, 90% and 98% of light within 18, 27 and 38 days, respectively, compared to soybeans, corn and oats - 25%, 30% and 69% at 38 days, respectively. See Graph 13.1 below. The measurements summarized below are measurements of percent light penetrating canopy to the soil. The difference from 100% is percent light intercepted by canopy.

Unico-B, Irene and Secuieni 1 tested 0.7%, 0.56% and 0.74%, respectively - above the 0.3% safe level at RCAT. Kompolti (0.06), Lovrin 110 (0.12) and Zolotonosha 13 (0.05) tested less than 0.3%. Tops, leaves and a 75% stem/25% top blend from Unico-B, field 1 were tested and resulted in 0.36%, 0.18% and 0.2% _9 THC. It is not established why Unico-B, Secuieni 1 and Irene tested beyond the 0.3% _9 THC level at RCAT. The hail damage on July 7/97 may be a factor contributing to this unexpected high level. The tops of Unico-B in field 1 only tested 0.36%. See Graph 14.1 below.

Tops, leaves and a 75% stem/25% top blend from Unico-B, field 1 were tested and resulted in 0.36%, 0.18% and 0.2% Δ9 THC. It is not established why Unico-B, Secuieni 1 and Irene tested beyond the 0.3% Δ9 THC level at RCAT. The hail damage on July 7/97 may be a factor contributing to this unexpected high level. The tops of Unico-B in field 1 only tested 0.36%. See Graph 14.1 above.
15. HEMP ROOT BIOMASS AND NUTRIENT COMPOSITION
Hemp roots produced about 3 x more biomass than corn roots per hectare in ½ the growing season Graph 15.1 below.

Industrial-Hemp has no psychoactive properties following definition of the European Economic Community (EEC); THC content is less than 0.3%. In general, low THC-seed varieties without psychoactive properties are those that have a THC content of less than 1%. (See also No-THC Hemp-seed.) THC= Delta-9 TetraHydroCannabinol.Copyright © 1995-2003 HempWorld, Inc. and Gordon Scheifele, Jean Marie Laprise et. al. Kenex, Ltd., All Rights Reserved.
