To achieve a good groundnut crop, simply applying fertilizer is not enough. The type of fertilizer, the right timing, soil condition, and the crop’s growth stage are also very important.
- 15–20 Days After Sowing
At this stage, the plants begin to establish and develop. Farmers should regularly monitor plant growth, leaf color, and soil condition in the field.
If symptoms of nitrogen deficiency are observed, corrective fertilizer management can be carried out as per the advice of an agricultural expert. Unnecessary or excessive application of urea in groundnut can lead to excessive vegetative growth and may also increase cultivation costs.
Timing: 🌱 15–20 Days After Sowing
- 25–30 Days – Beginning of Flowering
This is a very important stage for the groundnut crop. When flowering begins, gypsum, which is a good source of calcium and sulfur, can be beneficial for the crop.
The exact rate of gypsum application should be determined based on soil conditions and local agricultural recommendations.
Timing: 🌼 Approximately 25–35 Days After Sowing
- 35–45 Days – Pegging and Pod Formation Stage
At this stage, pegging and pod formation begin in the groundnut crop. Maintaining adequate soil moisture is very important during this period.
At this stage:
If gypsum is required, apply it as per the recommended guidelines.
Use micronutrients such as boron or zinc only if a deficiency is observed.
Avoid unnecessary or excessive application of micronutrients.
Timing: 🥜 35–45 Days After Sowing
- 45–60 Days – Kernel Filling Stage
At this stage, the kernels begin to fill inside the pods. Proper soil moisture management is important, along with regular monitoring of leaf color and overall crop health.
If symptoms of nutrient deficiency are observed, foliar sprays or other corrective measures can be applied based on soil/leaf testing or the recommendations of an agricultural expert.

⚠️ Important Note
It is not appropriate to apply the same type and quantity of fertilizer to every field. Fertilizer requirements vary depending on soil type, previous crop, rainfall, variety, and soil test results.
In particular, avoid applying urea and other nitrogen fertilizers in excess of the crop’s actual requirements.
