Deficiency of Zinc Sulphate in Paddy Crop
Zinc is an essential micronutrient required for the healthy growth and development of plants. It plays a crucial role in the formation of enzymes, proteins, and plant hormones. Zinc deficiency in crops can lead to stunted growth, reduced yields, and poor quality produce. In paddy crop, zinc deficiency is a common problem that affects the production of high-quality rice. Zinc sulphate is an effective fertilizer used to prevent and treat zinc deficiency in paddy crops.
Symptoms of Zinc Deficiency in Paddy Crop
The symptoms of zinc deficiency in paddy crop are often seen in young plants. The leaves of affected plants show a yellowing or mottling pattern, especially in the interveinal areas. The veins of the leaves may appear green due to the accumulation of chlorophyll. The leaves of the affected plants are small, thin, and flaccid, with a reduced blade size. The stems of the affected plants are thinner and shorter than healthy plants. The yield of the affected plants is reduced, and the quality of the produce is poor.
Causes of Zinc Deficiency in Paddy Crop
Zinc deficiency in paddy crop is caused by a lack of available zinc in the soil. Soil pH, soil structure, soil moisture, and soil type can all affect the availability of zinc to plant roots. Cold, wet soils can slow root growth, reducing the uptake of zinc. Sandy soils with a low organic matter content can also be deficient in zinc. High levels of phosphorus and iron can also reduce the availability of zinc to plant roots.
Treatment of Zinc Deficiency in Paddy Crop
Zinc sulphate is an effective fertilizer used to treat zinc deficiency in paddy crop. It can be applied as a foliar spray or soil amendment. Foliar application is the most effective method of treating zinc deficiency in paddy crops. Zinc sulphate can be added to the irrigation water or sprayed directly on to the leaves of the affected plants. The application should be timed during the vegetative growth stage of the plants, and the dosage should be adjusted according to the severity of the deficiency.
Prevention of Zinc Deficiency in Paddy Crop
Prevention of zinc deficiency in paddy crop can be achieved by ensuring that the soil has adequate levels of available zinc. Soil testing can determine the zinc availability in the soil and help determine if any additional zinc fertilization is necessary. The application of organic matter can improve soil structure and the availability of zinc to plant roots. Agronomic practices such as crop rotation and intercropping can also help to reduce zinc deficiency in paddy crops.
Conclusion
Zinc deficiency in paddy crop is a common problem that can lead to reduced yields and poor-quality produce. The symptoms of zinc deficiency are yellowing or mottling of the leaves, small and thin leaves, and reduced stem growth. Zinc sulphate is an effective fertilizer used to prevent and treat zinc deficiency in paddy crops. Foliar application is the most effective method of application; however, it can also be applied as a soil amendment. Prevention of zinc deficiency can be achieved through soil testing, organic matter application, and agronomic practices such as crop rotation and intercropping.
