What is the best fertilizer for peanuts?

Peanut fertilization time

1. Each growth stage of peanuts requires different nutrients. During the seedling stage, not much nutrients are needed, so just apply enough base fertilizer. After that, topdressing fertilizer is needed. When applying fertilizer, you can use the method of broadcasting and furrow application.

2. The growth direction of peanuts during the flowering period slowly changes to the reproductive growth stage, so it is necessary to apply top dressing to the plants in time to ensure that the plants have sufficient nutrition to promote flowering.

What fertilizer to use for peanuts

The seedling-promoting fertilizer for peanuts is quick-acting nitrogen fertilizer. Three to four kilograms of urea should be applied per mu to promote seedling growth and flower bud differentiation. Flower needle fertilizer should be applied during the flowering period, with five to six kilograms of urea, six to eight kilograms of diammonium sulfate, and five to six kilograms of potassium sulfate applied per mu. Six to eight kilograms of superphosphate should be applied during the pod-setting period, and foliar fertilizer should also be applied.

Peanut fertilization method

1. Apply sufficient base fertilizer to peanuts before sowing, and apply appropriate compound fertilizer, but do not apply too much phosphorus and potassium fertilizer. If the base fertilizer is insufficient during the seedling stage, fertilize in time before flowering, mainly with nitrogen fertilizer.

2. During the peanut pod-setting period, the nutrient demand and consumption are the largest in the entire growing period. During this period, topdressing mainly consists of potassium fertilizer, supplemented by nitrogen and phosphorus, to improve the disease resistance of peanuts.

3. After the peanut pods mature, their ability to absorb nutrients will gradually weaken. Appropriate application of foliar nitrogen fertilizer can promote the maturation of the pods, but care must be taken to control the amount of fertilizer used.

Precautions for peanut fertilization

During the growth process of peanuts, their absorption of nitrogen is mainly through nitrogen fixation by the plant's rhizobia, but the application of nitrogen fertilizer must also be controlled. If excessive application, it will easily lead to excessive growth and a decline in quality.
