Sure, here’s an article on the Dose of fertilizer in paddy crop.
Paddy crop, also known as rice crops, is one of the most common crops grown in India. To produce high-yield rice crops, farmers need to use a sufficient and balanced amount of fertilizers to prepare the soil with the necessary nutrients.
Fertilizers play a vital role in enhancing the soil quality and fertility. They provide essential elements like nitrogen, phosphorus, and potassium, which are the primary nutrients required for plant growth. In paddy cultivation, the soil is highly waterlogged, and farmers need to incorporate fertilizers appropriately to prevent nutrient losses.
NPK is a common term used to denote the fertilizer composition that contains Nitrogen(N), Phosphorus(P), and Potassium(K). The ratio of these nutrients varies depending on the soil type, water availability, and the crop type. For paddy crops, the recommended NPK ratio is 4:2:1.
The quantity of fertilizers required for paddy crops depends on several factors, including soil fertility, water availability, and crop growth stage. However, the most important determinant for fertilizer dosage is the soil test results.
Soil test analysis provides information on soil nutrients and pH levels. Based on soil test results, farmers can find out the exact quantity of chemical fertilizers required. Soil testing is essential because over-fertilization can have adverse effects on crop growth, quality, and the environment.
In the early stages of rice cultivation, farmers need to apply a basal dose of fertilizers. The basal dose is the first application of fertilizers done before planting. The basal dose fertilizers are applied on the soil surface, and the quantity is based on soil test analysis.
In the vegetative stage, which is when the crop is actively growing, farmers need to apply nitrogen fertilizer to meet crop requirements. Nitrogen fertilizers are applied in split doses for better crop uptake and to reduce nutrient loss due to leaching.
During the reproductive stage, which is a flowering and grain maturation stage, potassium and phosphorus are required in higher amounts. Farmers need to apply extra potassium and phosphorus fertilizers during this stage for better grain filling.
In conclusion, the correct dose of fertilizers is essential for a high-yield paddy crop. Farmers should conduct soil testing to determine the fertilizer requirements and apply them at the right stage to ensure efficient nutrient use and prevent environmental contamination. With the right amount of fertilizers, farmers can increase the yield, improve crop quality, and safeguard the environment.
