As hybrid rice cultivation has become increasingly popular among farmers, it is important to know the recommended fertilizer dose for obtaining high yields and better quality produce. Fertilizer management is a crucial factor in hybrid rice cultivation, as applying the right amount and type of fertilizer can make a significant difference in the growth and yield of the crops.
The recommended fertilizer dose for hybrid rice may vary depending on factors such as the soil fertility, climate, and the crop variety. However, there are some general guidelines that farmers can follow to achieve maximum yields and improve the quality of their produce.
Firstly, it is important to ensure that hybrid rice gets an adequate supply of nitrogen (N), phosphorus (P), and potassium (K) during its growth phases. Before planting, farmers should apply 30-40 kg N, 20-30 kg P, and 20-25 kg K per hectare. After 20-25 days of seedling growth, another 30-40 kg N should be applied, followed by another 30 kg N at 45-50 days of growth. Farmers can also supplement this with micronutrients such as zinc and iron.
Additionally, using organic manure or compost can also help improve soil fertility and provide the necessary nutrients for hybrid rice growth. It is recommended to apply 10-15 tons of organic manure or compost per hectare, preferably before planting.
Farmers should also keep in mind that excessive use of fertilizers can have adverse effects on the crops and the environment. Overuse of nitrogen, for example, can lead to lodging, disease susceptibility, and poor grain quality. It can also negatively impact the soil in the long term. Therefore, careful monitoring and application of fertilizer is essential for hybrid rice cultivation.
In conclusion, the recommended fertilizer dose for hybrid rice consists of providing adequate amounts of nitrogen, phosphorus, and potassium during different growth phases. Farmers can also supplement this with organic manure or compost and micronutrients such as zinc and iron. Careful monitoring and management of fertilizer use can help achieve maximum yields and improve the quality of the produce.
