After planting groundnuts how many weeks or days to applying fertilizer

For groundnuts, fertilizer application timing can vary based on soil test results and the specific nutrients needed. However, a common practice for post-planting application (often for phosphorus, potassium, or calcium, as groundnuts fix their own nitrogen) is:

• 3 to 6 weeks after planting (WAP), which is approximately 21 to 42 days after planting. This period generally coincides with early vegetative growth and the onset of flowering, which is a critical stage for nutrient uptake. Calcium, in particular, is often applied around the flowering/pegging stage directly to the soil surface.
