Fertilizer Dose at the Time of Paddy (Jhona) Transplanting
Paddy, also known as Jhona, is a widely cultivated crop in many parts of the world. It is a staple food for millions of people and plays a crucial role in global food security. To ensure a healthy and productive paddy crop, it is essential to provide the right amount of nutrients, especially during the transplanting stage.
During the transplanting process, seedlings are uprooted from the nursery and transplanted into the main field. This critical stage requires careful attention to ensure the healthy establishment and growth of the paddy plants. Adequate nutrient supply at this stage sets the foundation for the crop’s overall growth and productivity.
Let’s take a look at the recommended fertilizer dose for paddy transplanting:
1. Nitrogen (N): Nitrogen is a vital nutrient that promotes vegetative growth, leaf development, and overall plant vigor. The optimum dose of nitrogen for paddy transplanting is around 30-40 kg per hectare. Split application of nitrogen is beneficial, with 50% applied before transplanting and the remaining 50% applied in three subsequent splits: 10-15 days after transplanting, 35-40 days after transplanting, and finally, 60-65 days after transplanting.
2. Phosphorus (P): Phosphorus plays a significant role in root development, nutrient uptake, and energy transfer within the plant. An optimum dose of phosphorus for paddy transplanting is around 20-25 kg per hectare. It is advisable to apply the entire phosphorus dose at the time of transplanting itself, preferably in the form of superphosphate or diammonium phosphate.
3. Potassium (K): Potassium is crucial for overall plant growth, disease resistance, and water regulation within the plant. An optimum dose of potassium for paddy transplanting is around 20-25 kg per hectare. Similar to phosphorus, it is advisable to apply the entire potassium dose at the time of transplanting, preferably in the form of muriate of potash or potassium chloride.
4. Micronutrients: Although other essential nutrients like iron, zinc, copper, and manganese are required in trace amounts, they play a significant role in ensuring healthy plant growth and productivity. Soil testing can help determine the need for micronutrient application. Generally, micronutrients can be added through soil incorporation or foliar sprays if deficiencies are identified.
It is essential to mention that the recommended fertilizer doses may vary depending on various factors such as soil type, nutrient availability, and specific regional conditions. Consulting with agricultural experts or local agricultural extension offices can provide precise guidance tailored to specific paddy-growing regions.
Proper fertilization during paddy transplanting significantly influences the final yield and quality of the crop. However, over-application of fertilizers can harm the environment and cause nutrient imbalances. Hence, it is crucial to follow recommended doses and practices while applying fertilizers to optimize paddy growth while minimizing environmental impact.
In conclusion, paddy transplanting is a critical stage that requires careful attention to provide the right fertilizer dose. Nitrogen, phosphorus, potassium, and micronutrients play essential roles in fostering healthy growth and maximizing yield. Adhering to recommended fertilizer doses and consulting with agricultural experts will help paddy farmers achieve optimal results and contribute to overall food security.
