Cotton Nutrient Deficiencies and Remedies: The Secret to a Successful Crop

Cotton Nutrient Deficiencies & Remedies

As a result of the introduction of new high-yielding types and hybrids of cotton seeds, the rapid depletion of soil nutrients has become a limiting factor in cotton production. As a result, cotton farmers have raised the application rate of main plant nutrients in the form of concentrated fertilizers each year, resulting in the depletion of secondary and micronutrients from the soil. In this blog, we will take a look at the common nutritional deficiencies in cotton and their solutions.

Nutritional deficiency symptoms in cotton and their solutions

Nitrogen Deficiency


Nitrogen deficiency is the major cotton deficiency that a farmer needs to face. The most obvious sign of it in cotton plant is that the leaves are a pale yellowish green color and are getting smaller. In the end, the cells become disorganized, and red pigments called anthocyanins start to form. A plant that doesn’t have enough nitrogen also has little vegetative growth, lacks vigor, and grows slowly.

Nitrogen deficiency symptoms tend to be worse in cotton that grows in soils with a rough texture and not much organic matter.


You can administer urea-based fertilizers for cotton to cure nitrogen deficiency. It is a common cotton nutrient deficiency solution. Urea is a small organic compound that moves quickly into the plant. Within 6 hours, urea-N can be found in the bolls. Within 24 hours, most of the urea-nitrogen that the leaf took in will have moved into the bolls. Cotton will store nitrogen as protein in its leaves during times when there is more of it so that it can use it later.

Phosphorus Deficiency


Cotton plants with a phosphorus deficiency have smaller, darker green leaves. Cotton’s older, lower leaves are the first to show signs of shortage. Extreme phosphorus deficit causes not only a diminution in plant size but also a loss of secondary branches and a decrease in the total number of cotton bolls. The cotton bolls’ flowering, fruiting, and ripening are all slowed as a result.


The phosphorus shortage can be remedied by applying a foliar solution of DAP at a concentration of 2%.

Potassium Deficiency


Cotton rust is a striking sign of malnutrition caused by a lack of potassium. There are yellowish white spots on the leaves, and between the veins, the color of the leaves changes to light yellowish green. The tips and edges of the leaf break off and curl down. Lastly, the whole leaf turns reddish brown, dries out, and falls off the plant too soon. This stops the cotton bolls from growing normally, so they stay small and immature. Many bolls don’t open at all because the fiber inside isn’t very good.


Combating the nutrient deficiency of cotton such as Potassium is possible with foliar sprays(as potassium nitrate or potassium sulphate). The shortage can be remedied in as little as 20 hours with foliar K treatments. Three to four foliar applications of around 1.36 K/acre should be applied at least a week apart to address the deficit, depending on the cotton boll load.

Eliminating Cotton Nutrient Deficiencies: The Ultimate Solution

A high nutrient absorption rate is one of the most desirable characteristics of cotton seeds. With such type of cotton seeds, one can reduce the possibility of various nutrient deficiencies in cotton. Remember, addressing nutrient deficiency is a part of the holistic cotton plant protection plan. You need to combine it with cotton disease protection and cotton pest protection to achieve a good cotton crop.

A good cotton seed is the foundation of a good cotton crop. Buy cotton seeds online from Badi Kheti, India’s most trusted online seed seller with the top agriculture brands in India.
