Sure, here is an article on varieties of fodder maize:
Fodder maize, also known as corn silage, is a popular and productive feed crop for livestock. It is high in nutrition, energy, and fiber, making it an excellent choice for dairy cows, beef cattle, and other farm animals. However, not all fodder maize varieties are equal in terms of yield, quality, and adaptability. In this article, we will explore some of the most common varieties of fodder maize and their characteristics.
1. BMR (Brown Mid Rib)
BMR maize is a hybrid variety that is genetically engineered to have lower lignin content in its stalks and leaves. This results in a softer and more digestible plant material, which is particularly attractive to dairy cows that require a lot of fiber in their diet. BMR maize is known for its high yields, fast growth rate, and good resistance to diseases and pests. However, it may have lower starch content and grain yield compared to other maize varieties.
2. FAO (Food and Agriculture Organization) numbers
The FAO has developed a classification system for maize that helps farmers and researchers select the most suitable varieties for their region and climate. The FAO numbers indicate the number of days it takes for maize to reach maturity, from planting to harvesting, and are based on the growing season length and thermal requirements. For example, FAO 100-120 maize is suitable for areas with short growing seasons, while FAO 400-500 maize is best suited for tropical and subtropical climates.
3. Dent maize
Dent maize is a variety of maize that has an indentation or “dent” on the crown of each kernel when it is dried. This type of maize is usually grown for grain, but can also be used for silage if harvested at the right time. Dent maize is known for its high starch content, which makes it an excellent source of energy for livestock. It is also resistant to drought and has good adaptability to different soil types.
4. Silage-specific hybrids
Some maize varieties are specifically bred for silage production, meaning they are selected for their high fiber, moisture, and digestibility characteristics. Silage-specific hybrids are designed to optimize the fermentation process that occurs during storage, which helps preserve the nutritive value of the maize and prevent spoilage. Some examples of silage-specific hybrids are Pioneer 11C33, Dekalb DKC34-84, and Dairyland DS-2100.
5. High oil maize
As the name suggests, high oil maize is a variety of maize that has a higher oil content in its kernels compared to other varieties. This makes it a valuable source of energy for livestock, as well as for the production of biofuels and other industrial products. High oil maize is often used in feed blends to supplement other sources of protein and energy.
In conclusion, there are many varieties of fodder maize available, each with its unique qualities and benefits for livestock and farmers. The choice of maize variety depends on several factors, including climate, soil, management practices, and the intended use of the crop. By selecting the most suitable maize variety, farmers can maximize their yields, reduce costs, and provide high-quality feed for their animals.
