hygrometer: An instrument used for the measurement of humidity. Using hygrometers supports proper growing conditions for crops and livestock.

hl: Abbreviation for hectolitre. Understanding hectolitre measurements helps farmers manage liquid volumes effectively.

heterosis: An increase in size or rate of growth, fertility or resistance to disease found in offspring of a cross between organisms with different genotypes. Also called hybrid vigour. Using heterosis in breeding programs can improve livestock and crop performance.

hundredweight: A measure of weight of dry goods such as grain. Abbreviated after numbers to cwt: 5cwt. The British hundredweight is equivalent to 50.8kg, and the US hundredweight is equivalent to 45.4kg. Understanding hundredweight measurements helps farmers manage crop yields and storage.

hydrophobia: Same as rabies. Preventing and managing hydrophobia ensures the health and safety of livestock.

hybridise: To produce hybrids by crossing varieties of plants or animals. Practicing hybridisation improves crop and livestock performance and productivity.

hay fever: Same as pollinosis. Managing hay fever effectively can improve the health and productivity of farm workers during peak haymaking seasons.

heart: A muscular organ that pumps blood round an animal’s body. Ensuring the health of livestock hearts through proper nutrition and care improves their overall productivity.

herbage: The green plants, especially grass, eaten by grazing animals. Maintaining healthy herbage ensures nutritious feed for livestock and supports their growth and productivity.
