ID-250: An Introduction to Industrial Hemp and Hemp Agronomy
Rich Mundell, David Williams | Jul. 20, 2018 (New)
Cannabis sativa is a summer annual plant that is strongly photoperiod-sensitive (flowers according to day length/photoperiod; not physiological maturity). It is mostly dioecious in that male and female flowers occur on separate plants (i.e. there are both male plants and female plants). However, there are also several monoecious commercial varieties (male and female flower parts on the same plant). Different plant parts are harvested for specific purposes, and modern day hemp may be produced for one or more purposes. Depending on the harvestable component of interest, (i.e. fiber, grain or cannabinoids) male plants and/or pollen might be vitally necessary or completely unwanted.
ID-154: Low-Maintenance Lawn Care, Stressing Pest Avoidance and Organic Inputs
Dan Potter, A.J. Powell, Paul Vincelli, David Williams | Mar. 15, 2005 (Reprinted)
This publication is written for those who wish to maintain their lawn with minimal inputs. Low-maintenance lawn care offers certain benefits, such as minimal pesticide use, reduced fertilizer input, less need for irrigation, and reduced mowing frequency. However, when choosing a low-maintenance approach, recognize that the lawn will not offer the same dark green, uniform sward of turf that is seen under a high-maintenance lawn-care program.
