The pace of change in our personal and business lives
continues to accelerate at an ever increasing rate.
Accordingly, it is necessary to periodically update
information in a long-running reference such as Handbook
for Vegetable Growers. Our goal in this revision is to provide
up-to-date information on vegetable crops for growers,
students, extension personnel, crop consultants, and all
those concerned with commercial production and marketing
Protected cropping provides vegetable growers with an opportunity to enhance product
quality and improve food safety. The overall objective of this project was to provide
Vietnamese scientists and extension specialists with the training and tools to implement
and foster regionally feasible improvements to current vegetable production practices and
supply chains. This was achieved through: 1) greenhouse replicated experiments and
demonstration trials in Northern, Central and Southern Vietnam; 2) four in-country
workshops and 3) two Australian study tours for research and extension personnel.
As early as the beginning of the 20th century Rudolf Diesel proposed vegetable oil as
fuel for his engine.1 A short time later, before and during World War Two, vegetable
oil was examined in “up-to-date” diesel engines. In 1940 first trials with vegetable oil
methyl and ethyl esters were carried out in France and, at the same time, scientists in
Belgium were using palm oil ethyl ester as a fuel for buses.2 In 1973, the oil crisis
refocused attention on and interest for local energy sources.
