Hybrid Maize Revisited
Bob Hargrave
Over the years ECHO has been asked to give advice concerning whether or not to use hybrid seed. We carry very few hybrid varieties in our seed bank because we expect people who receive seed to multiply it locally. Now some new information about this old question, specifically about maize, has come to our attention.
Low Fertility Soil and Traditional Varieties
Joel Matthews received some feedback about his comments on low fertility soil and traditional varieties in EDN 86. In response, he sent the following additional comment.
Aflatoxin in Peanut Butter
The University of Zimbabwe (2002) studied the presence of aflatoxin in peanut butter.

Gray Water and Crop Irrigation
Larry Yarger and Dawn Berkelaar
“Gray water” (also “grey water,” “graywater” or “greywater”) is the term used to describe wastewater from dish washing, laundry, bathing, and rinsing. (Note: the term gray water does not refer to toilet waste, which is often called “black water.”) Although gray water does not need extensive treatment before it is used for irrigation, one must be careful as it can contain grease, hair, detergent, dead skin, food particles and occasionally fecal matter.
