Sure, here’s an article about the fertilizer dose for cotton at sowing time:
Fertilizer Dose for Cotton at Sowing Time
Cotton is an important cash crop cultivated all over the world. It is grown for its fiber, which is used in the textile industry. To achieve a good yield of cotton, proper fertilization is essential. Fertilizers provide essential nutrients to the plant, which are necessary for growth and development. Fertilizer application at the sowing time is an important step in the cotton cultivation process.
Fertilizer Requirements for Cotton
Cotton plants require a balanced supply of nutrients for optimum growth and yield. Nitrogen (N), phosphorus (P), and potassium (K) are the three primary macronutrients required by cotton. Calcium (Ca), magnesium (Mg), and sulfur (S) are also important secondary macronutrients. In addition, micronutrients such as zinc (Zn), iron (Fe), and manganese (Mn) are needed in small amounts.
Fertilizer Dose for Cotton at Sowing Time
The fertilizer dose for cotton at the sowing time depends on the nutrient status of the soil, the cotton variety, and the expected yield. Generally, a dose of 50-60 kg N, 40-50 kg P2O5, and 20-25 kg K2O per hectare is recommended for cotton cultivation. The nitrogen fertilizer should be applied in the form of urea, whereas the phosphorus and potassium fertilizers can be applied in the form of single superphosphate and muriate of potash, respectively. The application of micronutrients such as zinc, boron (B), and copper (Cu) may also be necessary depending on the soil conditions.
Fertilizer Application Methods
Fertilizers can be applied to cotton at the time of sowing using various methods such as broadcasting, drill application, and band placement. Broadcasting involves spreading the fertilizer uniformly over the soil surface. Drill application involves placement of the fertilizer in a narrow strip along with the seed during the sowing process. Band placement involves applying the fertilizer in bands next to the seed rows.
Conclusion
Fertilizer application at the sowing time is an important step in cotton cultivation as it provides the essential nutrients required for optimum growth and yield. A balanced dose of nitrogen, phosphorus, and potassium along with micronutrients can be applied using different application methods. Proper fertilization will enable the cotton plant to produce high-quality fiber and improve overall yield.
