As one of the most important crops in Asian countries, paddy or rice cultivation requires special attention when it comes to fertilization. The proper use of fertilizers is crucial for the optimal growth of the crop and the attainment of satisfactory yields. Here’s what you need to know about fertilizer doses when planting paddy or jhona.
First off, let’s talk about the different types of fertilizers that are commonly used in paddy farming. The primary nutrients that paddy needs are nitrogen (N), phosphorus (P), and potassium (K). The most common sources of N are urea, ammonium sulfate, and calcium ammonium nitrate. P can be obtained from single superphosphate and triple superphosphate, while K can be sourced from muriate of potash or potassium chloride.
Now, when it comes to the timing of fertilizer application during the paddy planting stage, there are typically two approaches. One is the basal application, which involves incorporating the fertilizers into the soil before planting the crop. The other is topdressing, which entails applying the fertilizers on top of the soil around the base of the plants after they have emerged and started growing.
For the basal application method, the recommended doses of N, P, and K for paddy planting are 75-100 kg/ha, 50-60 kg/ha, and 50-60 kg/ha, respectively. These fertilizers should be spread evenly and mixed well with the soil to ensure uniform distribution. The basal application should be done a few days before planting to allow time for the nutrients to become available to the plants.
On the other hand, for topdressing, the recommended doses of N, P, and K for paddy planting are 50-60 kg/ha, 25-30 kg/ha, and 25-30 kg/ha, respectively. The first topdressing should be done about 20-25 days after planting, followed by another application at 40-45 days after planting. When topdressing, care should be taken not to damage the emerging shoots or the roots of the plants. The fertilizers should be spread evenly around the plants and lightly incorporated into the soil surface.
It’s important to note that the actual fertilizer requirements for paddy may vary depending on soil type, climatic conditions, and other factors. Soil testing is recommended to determine the specific nutrient needs of your soil.
In conclusion, proper fertilization is crucial to maximize paddy yields, and the right timing and dosage of fertilizers are essential for achieving this goal. By following the recommended fertilizer doses and methods for paddy planting, you can help ensure the optimal growth and health of your crop.
