When to Apply Foliar Fertilizer to Peanuts? Analysis of the Best Spraying Time

Peanut is a common crop, and many regions rely on growing it to make money. To get a good peanut harvest, you need to fertilize well. So when should you apply foliar fertilizer to peanuts?

1. Seedling stage

During the peanut seedling stage, the focus is on growing the seedlings, so it is recommended to supply nitrogen fertilizer at this time. Although phosphorus and potassium fertilizers are also important, at this stage the nutritional consumption of these is indeed relatively small, with nitrogen fertilizer being consumed the most. You can consider nitrate nitrogen fertilizers or ammonium nitrogen fertilizers such as ammonium nitrate or ammonium chloride; of course, potassium nitrate is also a good choice.

2. Flowering stage

During the flowering stage, the peanut's nutritional demand for nitrogen fertilizer declines somewhat. In addition, since its own nitrogen-fixing capacity is relatively strong, there is no need to supplement nitrogen fertilizer at this time. You can appropriately increase the application of some phosphorus and potassium fertilizers. Phosphorus plays an important role in the growth and development of the peanut root system and root nodules, while potassium fertilizer can also promote flowering and prevent lodging. However, at this time, phosphorus and potassium fertilizer alone is still slightly insufficient. Science Xingnong suggests supplementing the peanut with some trace elements as well. Zinc (Zn) and iron (Fe) can increase yield and also help prevent disease.

In summary, you can consider supplementing with a multi-compound macro- plus trace-element foliar fertilizer such as monopotassium phosphate + zinc sulfate + ferrous sulfate. Of course, there are also specially sold trace-element fertilizers on the market that can be applied together with monopotassium phosphate, giving very good yield-increasing and disease-resistant effects.

3. Pod-setting and swelling stage

During the pod-setting and swelling stage, spraying monopotassium phosphate can promote the pod's demand for phosphorus and potassium fertilizer and greatly improve the peanut's potassium content and fruit plumpness.

It should be noted that when spraying foliar fertilizer, you must pay attention to controlling the concentration, be sure to follow the instructions, and do not blindly increase the dosage. Also, when spraying, pay attention to the weather and the spraying time to avoid wasted effort.
