In agriculture, precision seeding is a method of seeding that involves placing seed at a precise spacing and depth. This is in contrast to broadcast seeding, where seed is scattered over an area. [1]
Although precise hand placement would qualify, precision seeding usually refers to a mechanical process. A wide range of hand-push and powered precision seeders are available for small- to large-scale jobs. Using a variety of actions, they all open the soil, place the seed, then cover it, to create rows. There are also precision seeders for planting flats of seeds for indoor seed starting. The depth and spacing is generally adjustable to accommodate a range of crops and the desired plant density; the degree of adjustability depends upon the chosen seeder. [2]
In commercial production, precision seeding is an alternative to placing larger quantities of seed in a row, by dribbling seed or setting several seeds in each position. Depending on the device, precision seeders may place only one, or a very few seeds per position. This is an advantage, in that it saves seed and it avoids crowding, or the need for thinning, allowing plants the space to grow efficiently. On the downside, by placing fewer seeds, a very high germination rate is required to make full use of the seeded area. [3]
Sowing is the process of planting seeds. An area or object that has had seeds planted in it will be described as a sowed or sown area.
Precision agriculture (PA) is a farming management strategy based on observing, measuring and responding to temporal and spatial variability to improve agricultural production sustainability. It is used in both crop and livestock production. Precision agriculture often employs technologies to automate agricultural operations, improving their diagnosis, decision-making or performing. The goal of precision agriculture research is to define a decision support system for whole farm management with the goal of optimizing returns on inputs while preserving resources.
A tractor is an engineering vehicle specifically designed to deliver a high tractive effort at slow speeds, for the purposes of hauling a trailer or machinery such as that used in agriculture, mining or construction. Most commonly, the term is used to describe a farm vehicle that provides the power and traction to mechanize agricultural tasks, especially tillage, and now many more. Agricultural implements may be towed behind or mounted on the tractor, and the tractor may also provide a source of power if the implement is mechanised.
Weed control is a type of pest control, which attempts to stop or reduce growth of weeds, especially noxious weeds, with the aim of reducing their competition with desired flora and fauna including domesticated plants and livestock, and in natural settings preventing non native species competing with native species.
Pollination management is the horticultural practices that accomplish or enhance pollination of a crop, to improve yield or quality, by understanding of the particular crop's pollination needs, and by knowledgeable management of pollenizers, pollinators, and pollination conditions.
Dryland farming and dry farming encompass specific agricultural techniques for the non-irrigated cultivation of crops. Dryland farming is associated with drylands, areas characterized by a cool wet season followed by a warm dry season. They are also associated with arid conditions, areas prone to drought and those having scarce water resources.
A seed drill is a device used in agriculture that sows seeds for crops by positioning them in the soil and burying them to a specific depth while being dragged by a tractor. This ensures that seeds will be distributed evenly.
Thinning is a term used in agricultural sciences to mean the removal of some plants, or parts of plants, to make room for the growth of others. Selective removal of parts of a plant such as branches, buds, or roots is typically known as pruning.
Silviculture is the practice of controlling the growth, composition/structure, as well as quality of forests to meet values and needs, specifically timber production.
Iron sights are a system of physical alignment markers used as a sighting device to assist the accurate aiming of ranged weapons (such as a firearms, airguns, crossbows, and bows, or less commonly as a primitive finder sight for optical telescopes. Iron sights are the earliest type of sighting device, as it relies completely on the viewer's naked eye, and is distinctly different to optical sights such as telescopic sights, reflector sights, holographic sights, and laser sights, which make use of optical manipulation and/or active illumination.
In agriculture, gardening, and forestry, broadcast seeding is a method of seeding that involves scattering seed, by hand or mechanically, over a relatively large area. This is in contrast to:
A market garden is the relatively small-scale production of fruits, vegetables and flowers as cash crops, frequently sold directly to consumers and restaurants. The diversity of crops grown on a small area of land, typically from under 0.40 hectares to some hectares, or sometimes in greenhouses, distinguishes it from other types of farming. A market garden is sometimes called a truck farm in the USA.
Seed companies produce and sell seeds for flowers, fruits and vegetables to commercial growers and amateur gardeners. The production of seed is a multibillion-dollar global business, which uses growing facilities and growing locations worldwide. While most of the seed is produced by large specialist growers, large amounts are also produced by small growers who produce only one to a few crop types. The larger companies supply seed both to commercial resellers and wholesalers. The resellers and wholesalers sell to vegetable and fruit growers, and to companies who package seed into packets and sell them on to the amateur gardener.
A cultivator is a piece of agricultural equipment used for secondary tillage. One sense of the name refers to frames with teeth that pierce the soil as they are dragged through it linearly. It also refers to machines that use the rotary motion of disks or teeth to accomplish a similar result. The rotary tiller is a principal example.
Canna indica, commonly known as Indian shot, African arrowroot, edible canna, purple arrowroot, Sierra Leone arrowroot, is a plant species in the family Cannaceae. It is native to much of South America, Central America, the West Indies, and Mexico. It is also naturalized in the southeastern United States, and much of Europe, sub-Saharan Africa, Southeast Asia, and Oceania.
Kinze Manufacturing, Inc. is an American company that produces agricultural equipment.
A planter is a farm implement, usually towed behind a tractor, that sows (plants) seeds in rows throughout a field. It is connected to the tractor with a drawbar or a three-point hitch. Planters lay the seeds down in precise manner along rows. Planters vary greatly in size, from 1 row to 54, with the biggest in the world being the 48-row John Deere DB120. Such larger and newer planters comprise multiple modules called row units. The row units are spaced evenly along the planter at intervals that vary widely by crop and locale. The most common row spacing in the United States today is 30 inches.
Pachyrhizus ahipa, also called the ahipa or Andean yam bean, is a tuberous root-producing legume, which is mainly distributed in the Andean region.
Sorghum is an important staple crop for more than 500 million people in sub-Saharan Africa and South Asia, including many people in Nepal. In statistics collected from 1992 to 1994 about general millet, Nepal had an area of 0.21 million ha, with a yield rate of 1.14 (t/ha), and produced around 0.24 million tons of sorghum. The entirety of the crop is highly valued, with both the grain and the stem being utilized. The Terai region of Nepal tends to be more tropical which is ideal for the growth of sorghum. It tolerates hot climates better than maize or soybeans. For subsistence farmers, like those in Nepal, fertilizers are not necessary and the crop is frequently harvested by hand.
