Information about fertilizer dose in cotton at sowing time

Fertilizer is a crucial component of cotton cultivation, as it helps provide the necessary nutrients for the crop to grow and produce a robust yield. The right dose of fertilizer is essential to ensure the proper growth and development of the cotton plant. The following article provides information on the ideal fertilizer dose for cotton at sowing time.

There are three primary nutrients that cotton plants need in large quantities: nitrogen, phosphorus, and potassium. These elements are essential for plant growth and development, and deficiency in any of them can lead to stunted growth, poor quality cotton, and even a lower yield.

The recommended fertilizer dose for cotton varies depending on the soil type, ecological conditions, and other factors. However, a general rule of thumb for cotton cultivation is to apply 20-25 kg N, 40-50 kg P2O5, and 20-25 kg K2O per hectare at sowing time. The amount of fertilizer needed may also depend on the cotton variety, with some varieties requiring more nutrients than others.

Fertilizer application can be split into two – basal and top-dressing. Basal application of fertilizer is done at sowing time, while top-dressing is done later in the crop cycle. Typically, the basal application of fertilizer in cotton is done in rows or bands, around 5-10 cm deep and 5-8 cm away from the seed.

In addition to the primary nutrients, cotton plants also need secondary nutrients and micronutrients. Secondary nutrients include calcium, magnesium, and sulfur, while micronutrients include zinc, copper, boron, iron, manganese, and molybdenum. These nutrients are only needed in small quantities, but their deficiency can still have an adverse effect on cotton growth and development.

Before applying fertilizer, it is essential to determine the current nutrient status of the soil. This can be done by conducting a soil test to determine the nutrient content and then adjusting the fertilizer dose accordingly. Overuse of fertilizers can lead to environmental pollution and can reduce soil fertility, while underuse can result in low yields and poor-quality cotton.

In conclusion, the ideal fertilizer dose for cotton at sowing time is 20-25 kg N, 40-50 kg P2O5, and 20-25 kg K2O per hectare. Cotton farmers should conduct soil tests before applying fertilizer and adjust their dose accordingly to ensure optimal cotton growth and development. By providing the necessary nutrients, cotton farmers can enjoy a bountiful harvest and support the cotton industry’s continued growth.
