Fertilizer Dose in Direct Seeded Rice: Everything You Need to Know
Rice is a staple grain that a majority of the world’s population depends on. Farmers who cultivate rice have to be aware of the required fertilizer dose to ensure that their yields are optimized. Direct seeded rice (DSR) is a method of rice cultivation that has gained popularity because of its low labour input, less water usage and earlier maturity time. However, proper fertilizer application is necessary to ensure high yields. In this article, we delve into the fertilizer dose in direct seeded rice, the types of fertilizers used, and their application methods.
Types of Fertilizers
Fertilizers contain nutrients that are essential for plant growth. There are two broad categories of fertilizers used in direct seeded rice cultivation:
1. Organic Fertilizers: These are fertilizers that are derived from animal or plant residue, and they provide a natural source of nutrients to the plants. Examples of organic fertilizers include farmyard manure, compost, and green manure.
2. Inorganic Fertilizers: These are synthetic fertilizers that contain essential nutrients in their pure chemical form. Examples of inorganic fertilizers include urea, ammonium sulfate, and potassium chloride.
Fertilizer Application Methods
1. Broadcasting: This is a method of applying fertilizers by uniformly spreading them on the soil surface. It is the most common method of fertilizer application in direct seeded rice cultivation. Broadcasting is especially suitable for granular fertilizers such as urea.
2. Side-Dressing: This is a method of applying fertilizers by placing them on the soil beside the plant. It is effective for supplying plant nutrients to the roots directly. It is commonly used for liquid fertilizers such as ammonium nitrate.
Recommended Fertilizer Doses for Direct Seeded Rice
The recommended fertilizer doses for direct seeded rice will depend on various factors, including soil type, crop variety, and environmental conditions. However, some general guidelines are recommended:
1. NPK: NPK is a fertilizer that contains nitrogen, phosphorus, and potassium. It is essential for high yields in direct seeded rice cultivation. The recommended dosage for NPK fertilizer in DSR is 120 kilograms per hectare.
2. Urea: Urea is a type of nitrogen fertilizer that is commonly used in direct seeded rice cultivation. The recommended dosage varies depending on the soil type and crop variety. However, a general guideline is to apply 60 kg of urea per hectare at the time of sowing and another 60 kg per hectare during the tillering stage.
Conclusion
In summary, proper fertilizer application is essential for high yields in direct seeded rice cultivation. Organic and inorganic fertilizers can both be used, and the recommended dose will depend on the soil type, crop variety, and environmental conditions. Broadcasting and side-dressing are the commonly used fertilizer application methods. The general guideline for NPK fertilizer dosage in DSR is 120 kilograms per hectare, while urea is recommended at 60 kg per hectare at sowing and 60 kg per hectare during the tillering stage. With the right fertilizer doses and application methods, you can increase your direct seeded rice yield and contribute to meeting the world’s food demand.
