Foliar spray is an effective way of ensuring high yield in wheat crops. Wheat is an essential crop that provides food for humans and animals. The production of wheat largely depends on the health and vigor of the plants. Although wheat requires fertile and well-drained soil for optimal growth, foliar spray can also play a significant role in boosting yield.
Foliar spray is a liquid fertilizer applied to the crop leaves to supplement the nutrients in the soil. The application of foliar spray is particularly beneficial in a situation where the soil’s nutrient level is low or deficient. Foliar spray ensures that the plant absorbs the necessary nutrients directly through the leaves, resulting in faster growth, more robust plants, and an increase in yield.
For wheat crops, foliar spray can be used to boost yield in two ways:
1. As a source of growth regulators
Growth regulators are chemicals that control the plant’s growth, development, and physiological processes. Foliar spray containing growth regulators can increase both the yield and quality of wheat. Growth regulators such as auxins, gibberellins, cytokinins, and abscisic acid, when applied in the correct doses, can significantly improve wheat’s yield and quality.
2. As a source of essential nutrients
Foliar spray can also be used as a way of providing wheat crops with essential nutrients. Wheat requires a variety of nutrients, including nitrogen, phosphorus, and potassium. These nutrients are essential for the plant’s growth and reproduction and play a crucial role in the development of strong and healthy plants. Foliar spray containing the required nutrients ensures that the plants get these nutrients directly, leading to increased yields.
In conclusion, foliar spray is a vital tool for increasing wheat yields. The use of foliar spray in wheat farming provides the necessary nutrients and growth regulators needed for improved crop yield and quality. The yield increment of wheat crops from foliar spray is estimated to be between 10 – 30%. Farmers must use the right type of foliar spray and apply it in the correct dosage at the right time to maximize the benefits and mitigate the risks.
