What are the best times for topdressing peanuts?
Fertilizer is the guarantee of high yield for growers, so every stage of fertilizing and topdressing is extremely important. So how should peanuts be topdressed during cultivation? Which periods are the best times for topdressing? Let's learn some relevant knowledge about peanut topdressing below, so that your peanuts can also achieve high yields.
1. Base fertilizer
The base fertilizer is the stage of laying the foundation for peanuts. If the fertilizer at this stage is insufficient, the later growth will generally not be very good. The amount of fertilizer used at this time is also the largest, and the variety of fertilizer elements is also the richest, but try to avoid the peanut seeds coming into direct contact with the fertilizer. At this time, the peanut seeds only have a thin outer coat and can easily be corroded, leading to the death of the seeds. The fertilizers commonly used at this time include manure, urea, superphosphate, etc., with manure as the main one.
2. Rosette-stage fertilizer
The rosette stage refers to the period when the leaves and stems of the seedling stage begin to branch and form a cluster because they are relatively short. The advantage of topdressing at this stage is that it can ensure the later growth of the peanut seedlings. If the plants grow well, they can bear more peanut pods. The fertilizers used for topdressing at this stage are mainly those that promote the growth of peanut stems and leaves, allowing the entire peanut seedling to grow vigorously, so that more nutrients can be obtained later. At this stage, fertilizers such as urea and compound fertilizer are generally chosen for topdressing, and the effect is relatively obvious.
3. Flowering fertilizer
The flowering stage of peanuts is another good stage for topdressing. At this time, the main focus is on the root growth of the peanuts, making their roots grow faster and more vigorously, so that more root nodules will grow and create a good nutrient reserve for the subsequent large number of peanut pods. At this stage, phosphorus fertilizer, potassium fertilizer, and calcium fertilizer are mainly used, and the fertilizer should preferably be relatively close to their root system, so that the peanut seedling roots can better absorb nutrients.
4. Pod-setting fertilizer
Pod setting refers to the period when peanut pods gradually form below the peanut plants. This is basically the final sprint stage, and it is also a relatively important topdressing period. At this time, peanut plants have a relatively high demand for water and fertilizer nutrients, second only to the base fertilizer stage, and the fertilizers are mainly phosphorus and potassium fertilizers. If the soil is relatively dry, it is best to apply some aqueous fertilizer, so that both fertilizer and water are supplemented.
The above are several of the best topdressing periods for peanuts. If you want high yields, at the very least everyone must ensure that fertilization in this regard is adequate. If the land is somewhat mountainous, growers had better consider more use of water-soluble fertilizer, since such land is generally relatively dry.
