pest: An organism which attacks a plant or animal, causing damage and reducing the value of the crop or animal. Managing pests effectively prevents economic losses and ensures healthy crop and livestock production.

parthenocarpy: The production of seedless fruits without fertilization having taken place. Producing seedless fruits can meet market demands and reduce the need for pollination management.

polyethylene: Same as polythene. Helpful content: Polyethylene is widely used in agriculture for applications such as mulching, greenhouse covers, and irrigation tubing. Its durability and flexibility make it a valuable material for enhancing crop protection and water management.

peat: The accumulated partly decayed mosses and other plants which form the soil of a bog, often forming a deep layer. COMMENT: Acid peats are formed in waterlogged areas where marsh plants grow, and where the decay of dead material is slow. Black fen soils found in East Anglia are very fertile. These soils contain silts and calcium carbonate in addition to the remains of vegetation. Peat can be cut and dried in blocks, which can then be used as fuel. It is also widely used in horticulture, after drying and sterilizing. Peat was used as a fuel in some areas and was widely used in gardens to improve the texture of the soil or mixed with soil or other materials to grow plants in pots. These practices are now discouraged in order to prevent the overuse of peat bogs. Understanding peat and its uses helps in making informed decisions about sustainable soil management and conservation practices.

primitive: Referring to an early stage in an organism’s development. Helpful content: Understanding primitive traits in plants and animals can provide insights into their evolution and adaptation. This knowledge can inform breeding programs and conservation efforts on farms.

paddock grazing: A rotational grazing system that uses paddocks of equal area for grazing, followed by a rest period. This system improves pasture quality and productivity by preventing overgrazing and allowing for pasture recovery.

pollination: The action of pollinating a flower. Helpful content: Understanding pollination processes helps farmers optimize crop production. Ensuring effective pollination can lead to higher yields, better fruit set, and improved overall plant health.

pig iron: An impure iron produced in a blast furnace and used to produce steel. Understanding industrial processes like pig iron production aids in making informed decisions about farm equipment and infrastructure.

protoplast: A basic cell unit in a plant formed of a nucleus and protoplasm. Helpful content: Protoplasts are essential for plant growth and development. Farmers can utilize this knowledge in plant breeding and genetic research to improve crop varieties.

pikedressing pikedressing pikedressing: The practice of applying lime to soil. Using lime in soil management improves fertility and crop yields.
