vegetable: A plant grown for food, especially plants grown for leaves, roots, or pods or seeds that are usually cooked. Growing a variety of vegetables can provide a diverse and nutritious food supply, enhancing farm sustainability.

violet root rot: A common disease of sugar beet in which a violet-colored fungus (Helicobasadium purpureum) grows on the surface of the root. Managing violet root rot can prevent crop losses and improve sugar beet yields.

V-graft: A method of grafting where the stem of the stock is trimmed to a point and the stem of the cutting is split to allow it to be fitted over the point of the stock. Using V-grafts can improve plant propagation and crop yields.

vermicide: A substance that kills worms. Using vermicides can control parasitic worms in livestock, improving animal health and productivity.

VOC: Abbreviation for volatile organic compound. Managing VOC emissions can improve air quality and environmental sustainability on the farm.

vegetative propagation: The artificial reproduction of plants by taking cuttings or by grafting, not by seed. Using vegetative propagation can ensure consistent crop quality and improve farm productivity.

volatile organic compound: An organic compound which evaporates at a relatively low temperature. Managing VOC emissions can improve air quality and environmental sustainability on the farm.

vitamin A: A vitamin which is soluble in fat and can be synthesized in the body from precursors, but is mainly found in food such as liver, vegetables, eggs, and cod liver oil. Ensuring adequate vitamin A intake can improve animal growth and disease resistance.

verandah: A type of housing for poultry or pigs with a slatted or wire floor, through which the droppings fall. Using verandah housing can improve hygiene and reduce disease in poultry and pigs.

vine: A plant that supports itself by climbing up something or creeping along a surface. Growing vine crops can provide high-value produce and diversify farm income.
