Horticulture - In strict terms the scientific cultivation of fruit, vegetables, flowers and shrubs. Also used to describe the commercial production of such crops, some on general farms, but mostly on specialised holdings where soil, climate, skilled labour and irrigation can produce maximum yields of high-quality crops and where access to markets or good roads enable their sale at economical prices. Most horticultural enterprises have increasing output per unit area with the help of cultivation and environmental control, and the widespread use of machinery. On some farms the shortage and high cost of labour have led to the introduction of 'pick your own' harvesting for direct sales to consumers.

Husbandry - The economic management of a farm.

Husk - 1. The dry, thin, outer covering of certain fruits and seeds, e.g., the Glumes of cereal seeds.
2. A disease of cattle and sheep due to parasitic nematode worms, and typified by a husky cough and, when severe, difficult breathing.

Hybrid -  The offspring of parents of different species, varieties or breeds of plants or animals. They may be fertile or sterile. The likelihood of sterility is increased the greater the difference between the Genotypes of the parents, due to the increase chance of imperfect Chromosome pairing.

Hybrid Vigour -. Qualities in a Hybrid not present in either parent, e.g.,
increased hardines, improved growth rate.
