Sure, here’s an article on deficiency of Zinc Sulphate in paddy crop:
Zinc is an essential micronutrient required for the growth and development of plants. It plays a vital role in various physiological processes such as photosynthesis, carbohydrate metabolism, and protein synthesis. Zinc is also involved in the synthesis of chlorophyll, which is necessary for the growth of healthy paddy crops. Zinc deficiency in paddy crops can lead to stunted growth, reduced yield, and poor quality grains.
The importance of Zinc Sulphate
Zinc Sulphate is a commonly used source of Zinc for crops such as paddy. It is a water-soluble salt that is easily absorbed by the paddy roots, making it an effective and efficient fertilizer. Zinc Sulphate supplies Zinc to the plant, which is then taken up by the roots and transported to different parts of the plant.
Symptoms of Zinc deficiency in paddy crops
Paddy crops deficient in Zinc Sulphate display a variety of symptoms. The most prominent being chlorosis, which is the yellowing of the leaves due to a lack of chlorophyll. Other symptoms include delayed maturity, stunted growth, and small, malformed leaves. Plants may also display a reduced root system and lower yields for their size.
The cause of Zinc deficiency in paddy crops
Zinc deficiency in paddy crops can be caused by several factors. It’s important to recognize these factors so as to prevent Zinc deficiency in the first place. Some of the common causes of Zinc deficiency in paddy crops include:
1. High pH soils: High pH soils are deficient in Zinc because Zinc becomes less soluble and available to plants under high pH, especially when the soil contains high levels of calcium carbonate.
2. Sandy soils: Sandy soils are known for their low cation exchange capacity and their low ability to hold nutrients, making it challenging for plants to access nutrients in the soil.
3. Cool and wet environments: Zinc mobility in the soil decreases in the cool and wet environments, making it less accessible to the plant roots.
4. High phosphorus levels: High levels of phosphorus in the soil can lead to Zinc deficiency in paddy crops because the two nutrients compete for the same uptake sites.
How to prevent Zinc deficiency in paddy crops
Preventing Zinc deficiency in paddy crops begins with a good soil fertility program. Soil analysis before planting is crucial since it allows the necessary adjustments to be made before the crops begin to grow. Zinc Sulphate should be applied during the early stages of growth to ensure proper Zinc uptake.
Regular foliar applications have also proven to be an effective way to prevent Zinc deficiency in paddy crops. For maximum benefit, the foliar spray should be applied in the early morning or late evening when the stomata of the plant are open.
In conclusion, Zinc Sulphate is an essential nutrient for paddy crops. Zinc deficiency can lead to stunted growth, lower yield, and poor quality grains. To prevent Zinc deficiency in paddy crops, soil testing before planting is highly recommended, and the application of Zinc Sulphate during early crop growth stages is essential.
