Manganese sulphate is an essential micronutrient for wheat crops that plays a crucial role in various metabolic processes, including photosynthesis, nitrogen metabolism, and enzyme activation. The deficiency of this nutrient in wheat plants results in reduced yield, stunted growth, and poor quality grains.
To ensure adequate manganese supply to wheat plants, farmers often use manganese sulphate spray as a part of their fertilization program. However, to achieve the desired results, it is crucial to apply the spray at the right time and in the optimal dosage.
Timing of Manganese Sulphate Spray
The ideal time to apply manganese sulphate spray in wheat crops is during the vegetative stage when the plants are actively growing and developing new leaves. This stage usually occurs between the fourth and seventh week after seedling emergence when the plant has completed tillering and started elongating.
At this stage, the wheat plants have a high demand for manganese, and deficiency symptoms are likely to manifest if the nutrient is not provided adequately. It is recommended to apply the spray during the early morning or late evening when the weather is calm and cool to avoid evaporation or wind drift.
Dose per Acre of Manganese Sulphate Spray
The dose of manganese sulphate spray required per acre of wheat crop depends on several factors, including soil type, crop stage, weather conditions, and crop yield expectation. As a rough estimate, farmers can apply 1-2 kg of manganese sulphate per acre in the form of a spray solution.
It is essential to note that excessive use of manganese sulphate spray can lead to toxicity, which can cause severe damage to the wheat crop. Therefore, farmers must follow the recommended dosage guidelines and adjust them according to the specific needs of their crop.
Conclusion
In conclusion, applying manganese sulphate spray at the right time and optimal dose is crucial to ensure adequate supply of this essential micronutrient to wheat crops. Farmers should take into consideration several factors when determining the right dose and apply the spray during the vegetative stage of growth for optimal results. Proper manganese fertilization can help farmers achieve healthy crops, high yields, and better quality grains.
