As cotton is one of the most important cash crops in many parts of the world, it is crucial to apply effective fertilization practices to ensure healthy plant growth and high yields. In this article, we will discuss the recommended fertilizer dosages for cotton crops during the narma stage.
The narma, or the flowering stage, is the most critical stage of cotton growth, where the plants start to produce bolls and set the seeds inside. To promote healthy growth and maximize yield, cotton plants require a balanced supply of nutrients, including nitrogen, phosphorus, and potassium.
At the narma stage, the recommended nitrogen dosage for cotton crops is around 120-140 kg/ha. Nitrogen is essential for the development of leaves, stems, and roots, and it directly affects the plant’s photosynthesis. However, excessive nitrogen application can delay maturity and reduce fiber quality.
Phosphorus is another critical nutrient for cotton growth, especially during the early stages. At the narma stage, the recommended dosage of phosphorus is around 40-45 kg/ha. Phosphorus helps the plants develop strong roots, stimulates flower formation and fruiting, and enhances fiber quality.
Potassium is also essential for healthy cotton growth, especially during the narma stage, where the plants need a balanced supply of all nutrients to develop and mature the bolls. The recommended dosage for potassium varies depending on the soil type, but generally, it ranges between 100-120 kg/ha. Potassium strengthens the plant’s immunity, enhances stress tolerance, and improves fiber quality.
Apart from these major nutrients, cotton crops also need micronutrients such as zinc, iron, and manganese, which are often deficient in many soils. The recommended dosage of micronutrients is much lower than that of major nutrients, and it usually ranges between 2-3 kg/ha.
In conclusion, fertilization is a critical aspect of cotton cultivation, and the proper dosage of nutrients during the narma stage plays a crucial role in maximizing yield and fiber quality. Farmers should always consult with the local agricultural extension services or agronomists to determine the optimal fertilization practices for their specific soils and climate conditions.
