Manganese deficiency is a common problem that affects the production and yield of wheat crops. This deficiency occurs when the soil does not provide enough manganese to the plants. The symptoms of manganese deficiency include white or yellow stripes between the veins of the leaves, reddish-brown spots on the leaves, and reduced growth of the plant.
In order to control this deficiency, farmers and agricultural experts recommend several strategies. The first strategy is to ensure that the soil is properly prepared before planting wheat crops. Farmers should test the soil and add manganese fertilizer if necessary. The application of manganese fertilizers such as manganese sulfate or manganese oxide can help to increase the availability of manganese in the soil.
Another strategy is to maintain optimal soil pH levels. Manganese is more available to plants when the soil pH is between 5.5 and 6.5. Farmers can add lime to the soil to raise the pH or add sulfur to lower the pH.
In addition, farmers should practice crop rotation to prevent the buildup of manganese deficiency in the soil. Wheat should not be planted in the same field for more than two years in a row to avoid overuse of the soil.
Lastly, farmers can also use foliar application of manganese fertilizers. This method involves spraying a solution of manganese fertilizer directly onto the leaves of the wheat plants. This increases the uptake of manganese by the plant and reduces the incidence of deficiency.
In conclusion, the control of manganese deficiency in wheat crops requires a combination of strategies, including proper soil preparation, optimal soil pH, crop rotation, and foliar application of manganese fertilizers. By following these strategies, farmers can improve the yield and production of wheat crops.
