Types of Grain Sorghum

There are several types of grain sorghum, each adapted to different climates, soil conditions, and agricultural practices. For instance, some common types include:

• Forage Sorghum

  Forage sorghum is primarily grown for livestock feed and pastures. It is valued for its high biomass production and nutritional content.

• Sweet Sorghum

  Sweet sorghum is noted for its sugary stalks, which are rich in sap. This sap can be processed to make molasses, syrup, or biofuels like ethanol.

• Sorghum Bicolor

  This species is one of the most widely cultivated sorghums globally, known for its drought resilience and grain production. It is the main source of food grains in many sub-Saharan African countries.

• Sorghum Technicum

  This species is used primarily for producing Rapaduro, a type of unrefined sugar. This variety has a high sugar content, making it ideal for sugar production.

• Durra Sorghum

  This type of sorghum has hard, durable grains that are extremely hardy. It is a staple food source in arid regions and is highly resistant to drought and poor soil conditions.

• Tannin-Containing Sorghums

  These varieties have tannins in their grains. These tannins can discourage pests and birds, making the grain less palatable to certain organisms.

• Shattercane Varieties

  Shattercane is a wild relative of domesticated sorghum, identified as an invasive weed in some regions. Certain regions cultivate it for its hardiness and adaptability.

Growing and Extractions of Grain Sorghum

Growing of Grain Sorghum

• Land Preparation

  The land is ploughed and harrowed to create a suitable seedbed for planting. Farmers also conduct soil tests to determine nutrient levels and pH balance. This helps them decide on suitable fertilizers and amendments.

• Sowing

  Grain sorghum seeds are typically sown in the spring or early summer, when temperatures are warm. They have no problem growing in temperatures ranging between 20°C to 30°C. Farmers use seed drills or planters to ensure even spacing and proper planting depth, which is usually around 2 to 5 centimeters.

• Watering

  Sorghum is highly drought-resistant, but adequate moisture is important for optimal growth. Farmers aim to provide around 25 to 30 inches of rainfall equivalent per growing season.

• Nutrient Requirements

  Grain sorghum requires nitrogen, phosphorus, and potassium for proper growth. Farmers usually apply fertilizers based on soil tests. This ensures that the plants have the necessary nutrients to grow properly.

• Pest and Disease Management

  Farmers use integrated pest management (IPM) strategies to control pests and diseases. Pests and diseases are some of the major factors that reduce yields in farms. They can cause up to 70% wasting in some cases. This involves the use of both chemical and non-chemical methods.

• Harvesting

  Sorghum is usually ready for harvest about 3 to 4 months after planting. This is especially the case when optimal growing conditions are observed. Farmers monitor the moisture content of the grains to know the right time to harvest. They preferably harvest when the moisture content is between 20% to 25%.

Extraction of Grain Sorghum

The grain is harvested and dried to an appropriate moisture level. This is usually between 12% to 14%. The drying process helps prevent mold and ensures longer shelf life for the grains. Some common methods used to extract grain sorghum include:

• Mechanical Harvesting

  Many farmers use combines with specialized headers for sorghum. These machines are designed to minimize shattering since sorghum grains can easily break off the stalks.

• Threshing

  After harvesting, the grain is separated from the chaff and other plant materials. This is often done using threshing machines that rub the grains between tough surfaces.

• Hand Harvesting

  In small-scale or subsistence farms, hand harvesting with sickles or by stripping the grain from the stalks is common.

• Drying

  Once the grain is harvested, it needs to be dried to reduce its moisture content. This is because high moisture levels contribute to spoilage and reduce the effectiveness of pest control practices.

• Winnowing

  This is the process of separating the grains from lighter chaff, husks, and other debris. Traditional methods involve tossing the grain mixture in the air to allow the wind to carry away the lighter materials. There are also mechanical winnowers that perform this task more efficiently.

• Sieving

  After winnowing, the grains may still contain some small particles of chaff or broken husks. Sieving, using mesh screens or sieves, helps to further clean the grains by separating them from unwanted solid materials.

Benefits of Grain Sorghum

• Drought Tolerance

  Grain sorghum's robust root systems enable it to thrive in arid soils with low water retention.

• Nutritional Value

  Grain sorghum is rich in antioxidants, such as tannins and phenolic compounds. These antioxidants help combat oxidative stress and may reduce the risk of chronic diseases.

• High Fiber Content

  The high fiber content in grain sorghum promotes healthy digestion and regular bowel movements. It also helps in keeping a person full for a long time. This reduces food intake and is thus ideal for people who want to lose weight.

• Gluten-Free

  Sorghum's naturally gluten-free status makes it a safe and versatile option for people with celiac disease or gluten intolerance. They can consume it in forms like flour, grain treats, and pasta.

• Economic Benefits

  Sorghum's adaptability and resilience can contribute to more stable yields for farmers in challenging climates. They support local economies and reduce the need for grain imports, thus lowering grain costs.

• Used for Ethanol Production

  Grain sorghum can be converted into bioethanol, a renewable energy source. It provides an alternative to gasoline and reduces dependence on fossil fuels.

• Versatile Uses

  Sorghum grains can be used for various purposes, including animal feed, human food products, and industrial applications. Sweet sorghum has edible starchy leaves. This makes them a good option for forage or silage for livestock.

• Pest and Disease Resistance

  Sorghum's genetic diversity and hardiness make it more resistant to certain pests and diseases. This reduces the need for chemical pesticides and herbicides.

• Supports Biodiversity

  The diversity of sorghum varieties supports a wide range of wildlife, including birds and beneficial insects. These are some of the key natural controllers of pests.

Considerations When Buying Grain Sorghum Seeds

• Seed Variety

  Different grain sorghum seed varieties offer different yield outcomes, drought tolerance, and disease resistance. Assess the specific growing conditions in the target region. They include climate, soil type, and elevation. They will help in selecting the right variety.

• Yield Potential

  Buyers need to consider the yield potential of the seeds in order to settle for a product that has grain productivity potential. They should evaluate the seed’s yield potential, both in normal and stressful situations.

• Long-Term Investment

  Buyers also need to take into consideration the yield potential over time. They should look for information on how well the variety performed in previous growing seasons.
