Zinc is one of the essential micronutrients required by plants for their proper growth and development. Wheat is a cereal crop that is widely cultivated in many parts of the world. However, zinc deficiency is a common problem in wheat crops that affects their yield and quality. Therefore, it is important to know the information regarding the control of zinc deficiency in wheat crops.
One of the ways to control zinc deficiency in wheat crops is through soil application of zinc fertilizers. Zinc sulfate is a commonly used zinc fertilizer that can be applied to the soil before or during the growing season of wheat crops. The application rate of zinc sulfate depends on the soil type, crop yield potential, and the severity of zinc deficiency. However, it is important not to over-apply zinc fertilizers as it can lead to toxicity and have negative impacts on the environment.
Another effective way to control zinc deficiency in wheat crops is through foliar application of zinc fertilizers. Foliar application involves spraying the zinc fertilizer solution directly onto the leaves of wheat plants. This method is effective in correcting zinc deficiency in wheat crops that are already in their vegetative or reproductive stages. The timing of foliar application is critical as it should be done when the wheat plants are actively growing and have sufficient moisture.
In addition to zinc fertilizers, the use of zinc-enriched seed is also an effective method to control zinc deficiency in wheat crops. Zinc-enriched seed is produced by soaking the seed in a solution containing zinc before sowing. This method ensures that the young roots of wheat plants absorb sufficient zinc from the soil and hence prevents zinc deficiency.
It is also important to maintain the pH level of the soil within the optimum range of 6.0 to 7.5, as a high or low pH can affect the availability of zinc in the soil. Moreover, the use of organic fertilizers such as compost and manure can also increase the availability of zinc in the soil and hence prevent zinc deficiency in wheat crops.
In conclusion, zinc deficiency is a common problem in wheat crops that affects their yield and quality. The control of zinc deficiency can be achieved through various methods such as soil application and foliar application of zinc fertilizers, the use of zinc-enriched seed, and maintaining the pH level of the soil within the optimum range. It is important to apply these methods based on the severity of zinc deficiency and the crop growth stage for maximum effectiveness.
