🌾 Introduction
For achieving good production in groundnut, using only quality seeds is not enough. Balanced nutrient management at different stages of crop growth is also very important. In particular, the nutritional requirements of groundnut change during different growth stages such as early vegetative growth, flowering, pegging, pod development, seed filling, and seed quality improvement.
Water-soluble fertilizers dissolve easily in water and can help make essential nutrients quickly available to the crop. However, the type, quantity, and method of fertilizer application should be determined by considering soil fertility, crop condition, irrigation method, and local agricultural recommendations.
📅 Nutrient Management According to Crop Growth Stage
1️⃣ 25 Days After Sowing – Early Growth Stage
During this period, the roots, branches, and leaves of the groundnut plant develop rapidly. At this stage, balanced nutrition can help the crop establish healthy early growth.
A balanced water-soluble fertilizer such as 19:19:19 contains a balanced proportion of Nitrogen, Phosphorus, and Potassium (NPK). When applied according to the crop’s requirements and recommended practices, it can help provide essential nutrients for healthy early-stage growth.
2️⃣ 40 Days After Sowing – Flowering and Pegging Stage
At this stage, flowering begins in groundnut, followed by the pegging process. The availability of phosphorus and other essential nutrients becomes important for proper crop development.
A nutrient management program using 12:61:00 + Boron may support flowering and overall crop development when used appropriately. Boron application should be based on the crop’s requirements, soil/leaf test results, and local agricultural recommendations.
3️⃣ 55 Days After Sowing – Flowering and Pegging Stage
During this period, pegging and the initial development of pods are at an important stage in groundnut. Providing appropriate nutrition can support healthy crop growth and pod development.
A phosphorus- and potassium-based fertilizer such as 00:52:34 may be used according to the crop’s nutritional requirements. The recommended dosage and application method should always follow the product label and the advice of an agricultural expert.
4️⃣ 65 Days After Sowing – Beginning of Seed Filling Stage
At this stage, pod development and seed filling become important processes in the groundnut crop. Nutrients, particularly potassium, play an important role in crop development and seed quality.
A fertilizer such as 13:00:45 may be applied based on the crop condition and nutritional requirements. Proper nutrient management can help support seed filling and maintain good seed quality.
5️⃣ 80 Days After Sowing – Seed Filling and Quality
During the final growth stage of the crop, seed filling is a very important process. At this stage, the requirement for potassium may become important depending on the crop condition.
A potassium-based fertilizer such as 00:00:50 may be applied according to the appropriate recommendations. Proper application can help support seed filling and maintain overall crop quality.
🌿 Important Guidelines for Farmers
- Use fertilizers according to the actual nutritional requirements of the crop.
- Soil testing is beneficial for understanding soil fertility and nutrient status.
- Soil type, rainfall, irrigation, and crop conditions vary from field to field, so the same fertilizer program may not be suitable for every field.
- When using water-soluble fertilizers, follow the dosage and application method mentioned on the product label.
- Before mixing fertilizers with insecticides, fungicides, or other crop-protection products, check their compatibility.
- If rainfall is expected, avoid foliar nutrient sprays or select the appropriate application time according to local agricultural advice.
- If symptoms such as yellowing, reduced growth, leaf spots, diseases, or pest infestation are observed, do not simply increase fertilizer application; first identify the problem correctly.
- Excessive use of micronutrients such as Boron can be harmful, so they should be applied strictly according to recommendations.
⚠️ Important Note
The above stage-wise fertilizer program should be considered general guidance only. Soil type, rainfall, irrigation, variety, crop growth, and nutrient status can vary from one area to another. Therefore, before deciding the exact dosage, number of sprays, and product combinations, priority should be given to the advice of a local agricultural expert and the recommendations provided on the relevant fertilizer product label.
