Oats are a cereal grain, like wheat and barley. Their scientific name is Avena sativa, and they are also called common oats. The plant is grown mainly for its seeds, which are also called oats. People eat them as rolled oats, oatmeal and porridge, and oats are also an important food for horses and other farm animals. Oats are rich in fiber, which makes them a filling breakfast.
History
Compared with wheat and barley, oats were farmed quite late in human history. For a long time, wild oats were thought of as weeds that grew among other crops. People probably started growing oats on purpose about 3,000 to 4,000 years ago, in Europe and the Near East. Some of the oldest oat grains have been found in Egypt, but these were probably wild oats, not a planted crop. Ancient cultivated oats have been found at Bronze Age sites in Switzerland.
Anatomy
Oats is a grass that, in the course of time, grows to an individual leaf or tufted stem of about 1.5-3 ‘ tall. The grass is light green in color and they are hollow, cylindrical and tapering (terete) and smooth. The grasses of oats are hidden by the sheaths. Each stem or clump has a few alternate leaves.. In each leaf, you can see a 15 mm broad and 12 inches long blade. The blades and the sheaths are usually seen in medium blue green color. We can see the white membranous ligules
Habitat
Oats are not native to the Americas; they originally came from Europe and the Near East. European settlers brought oats to North America to grow as a crop. Today they are farmed in cool regions around the world for grain, straw and animal feed. Oats sometimes escape from farms and grow wild in old fields, along roadsides and beside railroads. They are also sometimes planted along roads to help stop soil erosion.
Soil
Oats prefer well drained soil. They like soft and deep soil as well.
Watering
Oats need a good amount of water to grow well, more than crops like wheat and barley. If the soil gets too dry, the plants become weak and produce less grain. Water them regularly, especially when the weather is hot and dry. Very hot or very cold weather stresses oat plants and can make them more likely to get diseases.
Temperature
The oat shows only a moderate resistance to cool climates. Unlike barley and wheat, oats does not grow in much lesser temperature and, if too cold the oat grass will die. Oats can grow well in cool climates but the fact is that they cannot live in very cold climates and they will die if the temperature is less than -8 C. The climate has to be moist for the plant to thrive well. If the climate is hot and very dry also, the oat grass will die. The fact is that oat is a winter crop but they cannot survive in freezing climates. Cool summers are best suitable for them to grow healthy
Pests and diseases
Oats are fairly hardy, but a few diseases can affect them. The most common are rusts, such as crown rust on the leaves and stem rust on the stems, which leave orange or brown spots. Some caterpillars and aphids also feed on oat plants. Farmers help prevent problems by planting disease-resistant varieties and rotating their crops.
Uses
Oats can be used for many a purpose. They are commonly used as food. They are used as oatmeal and they are powdered as oat flour. They are used to make biscuits, porridge, bread, noodles, etc. in certain places oats are used to make beer. They are also used to make several drinks.
Avena Sativa as a Nerve Tonic
