Manganese deficiency is a common problem in wheat cultivation, and it can lead to a significant reduction in yield. This micronutrient is essential for the plants’ physiological processes, such as photosynthesis, respiration, and the activation of numerous enzymes. In this article, we will discuss the control measures to tackle manganese deficiency in wheat crops.
Soil Fertility Management
Maintaining ideal soil fertility is essential for combating manganese deficiency in crops. In general, soils with a pH of 5.5 to 6.5 are ideal for wheat growth, and they must contain sufficient organic matter and nutrients. In addition, it is essential to conduct a soil test to determine the nutrient’s availability and adjust the soil pH accordingly. Soil amendments or fertilizers rich in manganese, such as manganese sulfate, can be added to soil in case of deficiency.
Seed Treatment
Seed treatments can be an efficient way of controlling manganese deficiency in wheat crops. Manganese sulfate seed treatment can be done by mixing the seeds with the solution. This treatment helps to ensure that the young seedlings have sufficient manganese to begin healthy growth.
Foliar Application
Foliar application of manganese can be an effective measure against this deficiency. It involves spraying the solution onto the plants’ foliage. The application should be done during the period of active growth, and it is recommended to avoid spraying during the hot day as this can cause burn on the plants’ leaves. Also, over application must be avoided as it can leads to leaf damage.
Crop Rotation
Another useful practice to control manganese deficiency in wheat crops is crop rotation. Crop rotation with legume crops, such as peas and beans, can provide additional manganese to the soil. Legumes have root nodules containing bacteria that can convert atmospheric nitrogen into a form readily available to the plants and improve soil nitrogen levels, a key nutrient needed for manganese absorption.
In conclusion, manganese deficiency can be detrimental to the growth and yield of the wheat crop. Soil fertility management, seed treatment, foliar application, and crop rotation are some of the measures that can be taken to combat the deficiency. These practices contribute to a healthy soil environment, reduced dependency on chemical fertilizers, and ultimately, help to improve yield and production.
