Fertilizer Dose in Paddy: A Complete Guide
Paddy or rice is a staple food crop grown in several countries worldwide. The yield and quality of paddy are influenced by various factors such as nutrient management, soil type, climate, water management, etc. Among these factors, fertilizer management has a significant impact on the yield and productivity of the crop. Thus, it is essential to have a proper understanding of the fertilizer dose in paddy cultivation.
Let’s explore in detail the factors influencing the fertilizer requirement for paddy and the recommended fertilizer doses.
Factors Influencing Fertilizer Requirement in Paddy
Soil Type: The soil type plays a crucial role in determining the fertilizer requirement for paddy cultivation. The soils that are rich in organic matter and nutrients require a lower dosage of fertilizer as compared to soils that are deficient in them.
Crop Variety: The fertilizer requirement for paddy also varies with the crop variety. Some rice varieties are more responsive to fertilizers, while others have low fertilizer requirements.
Water Availability: Paddy fields that have access to water throughout the growing season require higher doses of fertilizer, while rainfed fields require less fertilizer due to limited water availability.
Climate: In regions with a warm and humid climate, the decomposition of organic matter is higher, resulting in increased soil fertility. As such, the fertilizer requirement may be lower in such areas.
Recommended Fertilizer Dose in Paddy
The recommended fertilizer dose in paddy varies depending on the soil type, crop variety, water availability, and other factors. Generally, fertilizer application is done in two or three splits during the crop growing season.
Here are some general guidelines on fertilizer dose in paddy cultivation:
– Nitrogen: Paddy requires higher doses of nitrogen as compared to other nutrients. The recommended dosage of nitrogen ranges between 100 to 120 kg/ha for high-yielding varieties and 80 to 100 kg/ha for low-yielding varieties.
– Phosphorus: The recommended dose of phosphorus is usually around 40 kg/ha.
– Potassium: The recommended dose of potassium is around 60-70 kg/ha.
– Micronutrients: In addition to the major nutrients, paddy also requires some micronutrients like zinc, iron, and manganese. The recommended dose of these micronutrients varies from 5 to 10 kg/ha.
It is important to note that fertilizer dose should be determined based on crop needs and soil fertility. Overfertilization can lead to environmental pollution, soil degradation, and higher input cost. On the other hand, underfertilization can result in lower productivity and yield losses.
Conclusion
Fertilizer management is an essential aspect of paddy cultivation and has a significant impact on the yield and quality of rice. The fertilizer requirement in paddy varies with several factors like soil type, crop variety, water availability, and climate. Therefore, it is necessary to determine the fertilizer dose based on crop needs and soil fertility. With proper fertilizer management, farmers can increase their productivity and profitability in paddy cultivation.
