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.
How much of a supplemental nutrient to apply should be
determined based on prior experience of the farmer, obser-
vation of plant growth, knowledge of soil characteristics
such as organic matter, cation exchange capacity, phosphorus
and potassium supplying ability, and base saturation, knowl-
edge of crop needs and field history, and understanding of
the nutrient supplying power of the material to be used. An
example of nutrient application rates is provided in Table 2.
Overapplication can cause problems in crop production as
well as in the environment.
The title of this book is not ambiguous, but as it relates to a subject rarely thought about by the generality of
people, it may save some misapprehension if at once it is plainly stated that the following pages are in
vindication of a dietary consisting wholly of products of the vegetable kingdom, and which therefore excludes
not only flesh, fish, and fowl, but milk and eggs and products manufactured therefrom.
