What nitrogen management practice is recommended for cotton?

The practice of split applications of nitrogen is especially beneficial for cotton because it allows for a more efficient uptake of nutrients, aligning nitrogen availability with the crop's growth stages. When nitrogen is applied in multiple smaller doses rather than in one large application at planting, it can be more effectively utilized by the plant. This timing coincides with critical growth periods, particularly during rapid vegetative growth and just before and during flowering.

By promoting root biomass through split applications, this approach enhances the plant's overall health and productivity. Increased root development improves the plant's ability to access water and nutrients from the soil, which is crucial in the variability of soil moisture conditions often faced in cotton cultivation. Additionally, split applications can reduce the risk of nitrogen leaching and promote more sustainable nitrogen management practices, thereby contributing to both crop yield and environmental stewardship.
