Broadcasting in agriculture refers to a method of sowing or spreading seeds over a wide area by hand or using mechanical equipment. It involves scattering the seeds uniformly across the soil surface without placing them in specific rows or furrows. Broadcasting is commonly used for small-seeded crops, such as grasses, cover crops, or certain types of grains.

Manuring refers to the application of organic or inorganic materials to the soil with the intention of improving its fertility and providing essential nutrients to plants. It is a practice in agriculture where manures or fertilizers are added to the soil to enhance plant growth and yield.

Sprinklers are irrigation devices that deliver water to crops in the form of a spray or fine droplets. They are designed to simulate rainfall by distributing water evenly over the crop area. Sprinkler systems consist of sprinkler heads or nozzles, pipes, valves, and a water source.
