Pigeon pea, also known as Toor Dal or Arhar Dal, is a popular legume crop grown for its nutritious seeds. In order to achieve maximum yield and quality of pigeon pea, it is important to provide the right dosage of fertilizer to the crop.
The recommended fertilizer dose for pigeon pea crop is as follows:
1. Nitrogen (N): Pigeon peas are able to fix atmospheric nitrogen with the help of rhizobia bacteria present in their roots. Hence, nitrogen application is not required for pigeon pea crop. However, in case of very poor soil conditions, a small amount of nitrogen (around 20-25 kg/ha) can be applied during sowing.
2. Phosphorus (P): Phosphorus is essential for the development of roots and flowering in pigeon pea crop. The recommended dose of phosphorus for pigeon pea is around 25-30 kg/ha. It is advisable to apply phosphorus as a basal dose at the time of sowing.
3. Potassium (K): Potassium is important for the overall growth and development of pigeon pea plants. The recommended dose of potassium for pigeon pea crop is around 15-20 kg/ha. Potassium can be applied as a basal dose along with phosphorus at the time of sowing.
4. Micronutrients: In addition to the major nutrients, pigeon pea crop also requires micronutrients like zinc, iron, copper, manganese, and boron for healthy growth. It is recommended to apply micronutrients in the form of foliar spray or soil application based on the soil test results.
It is important to note that overuse of fertilizers can lead to nutrient imbalances in the soil, which can adversely affect the growth and yield of pigeon pea crop. Therefore, it is advisable to conduct soil tests before applying fertilizers to determine the nutrient status of the soil and to provide the appropriate dosage of fertilizers.
By following the recommended fertilizer dose for pigeon pea crop, farmers can ensure healthy growth, high yield, and good quality of the crop. Proper fertilization practices not only improve the productivity of pigeon pea crop but also contribute to sustainable agriculture practices.
