Oat Crop Details for Exam

The oat (Avena sativa), popularly known as the common oat, is a type of cereal grain produced for its corresponding seed (usually in the plural, unlike other cereals and pseudocereals). Although oatmeal and rolled oats are good for human consumption, one of the most popular uses for oats is as livestock feed.

About Oats

Oats are next only to rye in the temperate parts of the world in terms of their capacity to survive on deficient soils. Despite being primarily used as animal feed, some oats are processed for human use, particularly as breakfast dishes. Under ideal circumstances, the plants give great grazing, decent hay, and good silage (stalk feed preserved by fermentation). Red oats, which are more heat tolerant, are primarily planted in warmer climates while common oats are cultivated in cool temperate regions. On sandy, infertile, or extremely acidic soils, the crop will grow if there is enough precipitation. The plants are generally free of pests and diseases, although their stems and leaves are vulnerable to rust and anthracnose.

History of Oats

The hexaploid wild oat, A. sterilis, is the wild ancestor of Avena sativa as well as the closely linked minor crop, A. byzantina. The Fertile Crescent of the Near East was where A. sterilis’ ancestors first appeared, according to genetic data. Oats are typically regarded as a secondary crop, meaning that they were domesticated in the Middle East and Europe after first emerging as a weed among the primary cereal domesticates and moving westward into cooler, wetter climates.

Oats Climate Requirements

Temperate locations are the greatest places to cultivate oats. They are especially crucial in regions with mild, rainy summers, like Northwest Europe and even Iceland, as they require less summer heat and can withstand more rain than other cereals like wheat, rye, or barley. Oats are an annual plant that can be sown in the spring or the fall for harvest in the late summer (for early autumn harvest). It grows well in environments with temperatures between 15 and 25 degrees Celsius. 80 to 100 mm of rain is ideal. The ideal sowing temperature range is 20 to 40 °C. Temperatures for harvesting should range from 25 to 30 °C.

Oats Soil Requirements

Oats can be grown on a variety of soil types. However, they do best on loamy soils with good organic matter and good drainage. For a higher yield, a soil pH range of 5.0 to 6.5 is ideal. Oat crops may grow in soils with a wider pH range than wheat or barley.

Oats Farming Techniques

It is essential to prepare the grains before sowing. Oat seeds are split into first and second grains, which have quite different shapes and sizes, in order to prepare the grains for sowing. The initial grains grow into strong, high-yielding plants with good tillering. Plants that develop from second-generation grains produce less. Oats must have their seeds treated with 40% formalin five days before planting. Dry and semi-dry procedures are used to treat seeds. This helps grains stay viable in the spring without affecting germination. It is carried out 30 to 60 days before planting. Only seeds with a moisture level of under 14% are subject to pre-treatment, it should be emphasised. A semi-dry treatment should be applied to the seeds two to three days prior to sowing if the moisture content is higher than 17%.

Rows of oats are spaced 15 cm apart. Oats are sown at a rate of roughly 20–25 g of seeds per square metre. Oats seeds should be planted 3 cm deep on heavy soils, 2 cm deep on cultivated soils, and 4–6 cm deep on light and dry soils. Before weeds emerge, thick soils can benefit from gentle harrowing to break up the soil crust and eradicate weed seeds. To lessen the number of weeds, a second harrowing might be done during the tillering stage.

Oats Physiology

Oats are yearly plants that can grow to a height of 1.5 metres (5 feet). The long leaves have a membrane ligule and rounded base sheaths (small appendages where the leaf joins the stem). The plant’s inflorescence, or flowering and fruiting structure, is made up of multiple branches with florets that develop into the caryopsis, or single-seeded fruit.

Oats Crop Development

The key oat growth stages are shown below:

1. Germination:
   The seeds now start to absorb water, expand, and grow. Oat seed is particularly susceptible to infections at this stage.
2. Leaf development:
   The first leaf of the plant occurs during this stage of oat growth, breaching the surface.
3. Tillering:
   At this point, extra stems known as “tillers” start to emerge and are joined to the main stem underground. Tillering continues until the plant switches to its reproductive form and stops growing leaves.
4. Stem elongation:
   This stage of oat growth is sometimes referred to as “jointing,” and it refers to the nodes (joints) which appear above ground at this stage.
5. Flowering:
   This is the oat plant’s blossoming stage. The panicle blooms first at the top. The panicle’s outside edge continues to flower. Before the head fully emerges from the boot, the plant may already be in bloom. Usually, the anthers are invisible.
6. Ripening:
   The grain has grown to its full size and is fully mature at this point. As water is lost, drying happens. Weather factors have a big impact on how long this time period will last.
7. Senescence:
   This is the last stage of oat growth. The plant is fully mature and ready to be harvested.

Oats Crop Diseases

Various fungal, bacterial, viral, nematode and other diseases affect oats. The most essential disease that is likely to affect a crop is influenced by the environment and the part of the world where the crop is grown. Some oat varieties are disease resistant.

Oats Harvesting

Techniques for harvesting depend on the equipment that is available, regional customs, and priorities. When the greenest kernels are just starting to turn cream-coloured or when the moisture content of the kernels has reached 35 percent, farmers harvest their crops for the best yield possible. After cutting the plants approximately 10 cm (4 inches) above ground, they harvest by swathing, placing the cut plants into windrows with the grain all facing in the same direction. Before coupling the windrows with a pickup header, they let them dry in the sun for a few days. They finally bale the straw.

After 75 to 85 days of seeding, 50% of the oat crop can be harvested. Four hundred quintals of green fodder can be obtained by harvesting fifty percent of the crop. With the second harvest taking place after 50% flowering, the crop generated for two harvestings should indeed be harvested in 55 to 60 days. Approximately 550 quintals of green fodder will be produced per acre during this crop. At a height of 4 to 5 centimetres, the plants should be harvested. They reach full maturity and are ready to be harvested four to five months after being sown, or you might say they are ready to be harvested in early April.

Oats as a Food

Oats can be used in a variety of ways in food, but they are most frequently processed into fine oat flour or rolled or crushed into oatmeal. Although oatmeal is most commonly consumed as porridge, it can also be found in a number of baked foods, including oatcakes, biscuits, and bread. Numerous cold cereals, in particular muesli and granola, have oats as a component. Additionally, oats are utilised to make milk alternatives (“oat milk”).

In Scotland, a dish is prepared by soaking oat husks for a week; the fine, floury portion of the meal was then filtered off, cooked, and consumed as sediment. Like barley or rice might be used in other nations, oats are also commonly utilised there as a thickening in soups. Oats are occasionally added to a variety of beverages. They are occasionally used to make beer in Britain. One type of stout that contains some oats in the wort is oatmeal stout. Scottish tradition calls for steeping oats in whisky and combining the resulting “brose” with honey and occasionally cream to create Atholl Brose. Avena, a cold, sweet beverage prepared with milk and ground oats that is popular throughout Latin America, is known by the Spanish name. Oliver Cromwell loved oatmeal caudle, a classic British beverage comprised of ale, oatmeal, and spices.

Oats Nutritional Information

Oats Health Effects

By making you feel full, oats may lower cholesterol and blood sugar levels and aid with appetite control. Oat bran may function by preventing the intestines from absorbing elements that can cause diabetes, high cholesterol, and heart disease. When applied to the skin, oats appear to lessen oedema. Diabetes, heart disease, and high cholesterol can all be treated with oat bran and whole oats. There isn’t any solid scientific evidence to back up their usage for these additional illnesses, including high blood pressure, cancer, dry skin, and many others.
