This article investigates the technical feasibility of small-scale oilseed production and on-farm processing of biodiesel and livestock feed using primary data from two Vermont farms. Results indicate that small-scale production of sunflowers, canola, and soybeans, and on-farm processing of livestock feed and biodiesel are technically feasible, but yields depend on many factors. Increased local expertise, information-sharing among the farm and Extension communities, and improved access to harvesting and processing equipment can improve productivity and efficiency. Additional experience in seed drying and expeller pressing techniques should reduce fat content in the seed meal, improve meal value, and improve oil production efficiency. …

Pigeonpea (Cajanus cajan) is an annual or short-lived perennial food legume of acute regional importance, providing significant protein to the human diet in less developed regions of Asia and Africa. Due to its narrow genetic base, pigeonpea improvement is increasingly reliant on introgression of valuable traits from wild forms, a practice that would benefit from knowledge of its domestication history and relationships to wild species. Here we use 752 single nucleotide polymorphisms (SNPs) derived from 670 low copy orthologous genes to clarify the evolutionary history of pigeonpea (79 accessions) and its wild relatives (31 accessions). We identified three well-supported lineages …

This article addresses the economic costs of good agricultural practices (GAPs) audits of small and medium size farms in Vermont. It focuses on the costs of infrastructure, equipment, and labor required to successfully pass a U.S. Department of Agriculture (USDA) GAPs audit. In-depth interviews and surveys of produce farmers in 2011 revealed that the cost of GAPs certification ranges between $37 and $54 per acre, and an additional 7 hours were required each week during the growing season. Based on this exploratory research, certifying all the farms in Vermont would cost between $228,216 and $3,019,114. Our study explored all the …
