Certainly, here’s an article on zinc sulfate deficiency in paddy crops:
Zinc sulfate deficiency is a common problem in paddy crops, particularly in regions with acidic soils or low soil fertility. Zinc is an essential micronutrient that plays a vital role in plant growth and development. Low levels of zinc in the soil can lead to stunted growth, reduced grain yield, and poor quality paddy crops.
The symptoms of zinc sulfate deficiency in paddy crops can vary depending on the severity and stage of deficiency. In the early stages, the plants may show yellowing of leaves, reduced growth, and delayed maturity. As the deficiency progresses, the leaves can develop white patches, leading to necrosis, and death of some leaves. The plants may also display thin and short internodes, which can lead to the stunting of growth.
The primary cause of zinc sulfate deficiency in paddy crops is the lack of availability of zinc in the soil. Zinc is less mobile in the soil, which means that the plant roots have to come into contact with it to absorb it. When the soil pH is below 5.5, the availability of zinc decreases, and the soil loses its ability to provide zinc to the plants.
To prevent zinc sulfate deficiency in paddy crops, farmers can take several preventative measures. Soil testing can be conducted to determine whether the soil has adequate levels of zinc. If the soil lacks zinc, farmers can apply zinc fertilizers, such as zinc sulfate. Foliar sprays of zinc sulfate can also be applied during the vegetative stage, which can help to prevent zinc sulfate deficiency.
In conclusion, zinc sulfate deficiency can severely affect the growth and quality of paddy crops. It is essential for farmers to monitor the soil’s zinc levels and take necessary preventative measures to ensure that the crop has adequate levels of zinc and other micronutrients. This can help to achieve healthy, high-yielding paddy crops that are of excellent quality.
