Certainly, as an AI language model, I can provide you with an article on “Fertilizer Dose in Paddy Nursery.”
Paddy, also known as rice, is the most important staple food for more than half of the world’s population. However, the yield of rice crops is influenced by various factors. Proper nutrient management is essential in achieving maximum yield in paddy cultivation. In this regard, adequate fertilizer dose in paddy nursery ensures optimum growth conditions for the germinated rice seeds.
The following are some key points to consider when using fertilizer dose in paddy nursery:
1. Significance of the Fertilizer Dose
The fertilizer dose plays a crucial role in the development of rice seedlings. It supplies essential nutrients for the growth of nursery plants, promotes the development of robust roots, sturdy stems, and healthy leaves.
2. Selecting the Fertilizer
There are different types of fertilizers available, such as organic, inorganic, and biofertilizers. Inorganic fertilizers, such as urea, DAP, and MOP, are widely used in the paddy nursery. Organic fertilizers, such as compost and vermicompost, are used to provide long-term nutrient supply. Biofertilizers, such as Rhizobium, Azospirillum, and Phosphobacteria, improve soil fertility, and enhance plant growth.
3. Fertilizer Composition
The fertilizer dose should be composed of a balanced ratio of macronutrients, such as nitrogen (N), phosphorus (P), and potassium (K). A commonly used nitrogen-phosphorus- potassium (NPK) ratio is 20:20:20. Additional micronutrients, such as boron, iron, and zinc, can also be added in form of foliar spray.
4. Fertilizer Application
The fertilizer dose is usually applied in two or three split doses. The first dose should be applied five to seven days after sowing, the second dose about two weeks after sowing, and the third dose at around the 21st day. The application should be done uniformly to avoid burning of the seedlings.
5. Precautions While Applying Fertilizer
Care should be taken no to exceed the recommended fertilizer dose, as excess fertilizer can lead to reduced seed germination and slow growth. In addition, because of the prominence of nitrogen, fertilizer may attract pests and disease to the nursery is the application is not done accurately and uniformly.
In conclusion, adequate fertilizer dose in paddy nursery is incredibly important to boost the nutrient levels of the soil, improve its fertility and boost the growth of rice seedlings. Proper application of fertilizers following the recommended guidelines can help farmers achieve maximum yields and grow healthy, robust crops. Farmers need to bear in mind that excess use of fertilizer may do harm and limit the yield of their crops.
