Sure, here’s an article on the time and procedure of application of fertilizer for ahu rice (direct seeded):
Ahu rice is one of the most popular varieties of rice in South and Southeast Asia, known for its high yield and excellent taste. To get the most out of your ahu rice crop, it’s essential to understand the proper time and procedure of applying fertilizer to the soil.
Fertilizer application is a critical aspect of rice cultivation, and it determines the quality and quantity of the yield. Here are the steps you can follow to apply fertilizer to your ahu rice field:
1. Soil testing: The first step is to conduct a soil test to determine the soil’s nutrient levels. Soil analysis helps you determine the exact fertilizer requirements and plan the application process accordingly. It’s recommended to do a soil test at least two months before planting.
2. Pre-planting fertilizer application: Before planting the ahu rice, it’s essential to apply a basal dose of fertilizer to the soil. The amount and type of fertilizer depend on the soil test results. Apply the fertilizer to the soil and mix it thoroughly. It’s best to apply the fertilizer at least two weeks before planting.
3. Top-dressing: The second application of fertilizer is known as top-dressing. This application is done when the rice is in the vegetative stage and has fully established itself. The timing and amount of fertilizer depend on several factors such as the soil type, weather conditions, and crop growth. Top-dressing should be done at least 30-40 days after planting.
4. Nitrogen fertilization: Nitrogen is a crucial nutrient for rice plants, essential for its growth and development. A deficiency of nitrogen results in stunted growth and reduced yields. Nitrogen can be applied in the form of urea or ammonium sulfate. The recommended amount of nitrogen varies depending on the soil test results, crop growth and development, and weather conditions.
5. Fertilizer application methods: There are several methods of fertilizer application, such as broadcasting, banding, and deep placement. Broadcasting involves applying the fertilizer uniformly over the soil surface. Banding involves placing the fertilizer in bands on either side of the crop rows. Deep placement involves inserting the fertilizer below the soil surface.
In conclusion, proper fertilizer application is crucial for the optimal growth and development of your ahu rice crop. By following the right procedure and timing, you can ensure a healthy and high-yielding crop, resulting in better returns for your investment. So, take the help of an expert and carry out soil testing to determine the exact requirements of your ahu rice crop before fertilization.
