Manganese is an essential micronutrient required for the growth and development of plants. Wheat is one of the most important cereal crops in the world and is extensively grown for its grain. However, the deficiency of manganese in wheat plants can substantially reduce the yield and quality of the crop.
Manganese deficiency in wheat can be caused due to several reasons, such as low availability of the nutrient in the soil, high pH, low organic matter content, and excess of other nutrients like iron, aluminum, and calcium. The symptoms of manganese deficiency are mainly visible on the younger leaves of the plant and include yellowing, interveinal chlorosis, and stunted growth.
To control manganese deficiency in wheat, it is important to ensure an adequate supply of the nutrient in the soil. One way to achieve this is by applying fertilizers containing manganese. Manganese fertilizers can be applied either as foliar sprays or soil applications. Foliar sprays are generally preferred for a quick response, while soil application can provide long-term benefits.
Apart from fertilization, other cultural practices can also help in improving the uptake of manganese by wheat plants. These include maintaining optimum soil pH (5.5-6.5), increasing organic matter content, and avoiding the application of other nutrients in excess.
In addition to these practices, genetics also play a crucial role in the uptake and utilization of manganese by wheat plants. Therefore, the development of high-yielding varieties with improved manganese uptake efficiency can also be an effective strategy to control manganese deficiency in wheat.
In conclusion, manganese deficiency is a significant concern for wheat growers as it can reduce the crop’s yield and quality. To control this deficiency, a combination of strategies like fertilization, cultural practices, and genetics can be used. It is essential to maintain an adequate supply of manganese in the soil to ensure optimum growth and development of wheat plants.
