Like human beings, plants also go through deficiency of different nutrients. The insufficiency of nutrients in plants can be primarily judged through colour and texture of leaves.
Nutrient deficiencies in plants can be identified by their leaves, i.e. leaf color and leaf texture. Here we will tell you how to test for nutrient deficiencies in the form of symptoms.
In plants, the nutrient deficiencies appear in the leaves first which can be used as an important indicator of the overall health of the plant.
The growers recognizing and understanding these symptoms as early as possible can effectively address the problem by providing their crops with the nutrients they need to ensure optimal growth and high yields.
(a). Nitrogen deficiency:
Nitrogen is an important nutrient for cabbage.
Symptoms: Yellowing of older leaves (chlorosis), starting at the tips and progressing towards the center. Growth may be stunted.
Reason: Nitrogen is mobile in plants, so its deficiency first appears in older leaves as nutrients are diverted to younger tissues.
(b). Phosphorus deficiency:
Phosphorus is an important nutrient for cabbage.
Symptoms: Dark green or purple color of older leaves due to anthocyanin build-up, poor root development, and slow growth
Cause: Phosphorus deficiency affects energy transfer in plants, especially in the early growth stages.
(c). Potassium deficiency:
Potassium is an important nutrient for cabbage.
Symptoms: Browning or scorching of leaf edges, i.e. slight scorching appearance, curling, and yellowing between the veins in older leaves (interveinal chlorosis)
Cause: Potassium helps regulate water use and enzyme progression, so its deficiency results in reduced drought tolerance and weakened plants
(d). Sulfur deficiency:
Sulfur is an important nutrient for secondary nutrients.
Symptoms: Uniform yellowing of young leaves (similar to nitrogen deficiency but affects new leaves first).
Reason: Sulfur is immobile in plants and is essential for protein synthesis
(e). Magnesium deficiency:
Magnesium sulfate is the main dietary component of secondary components.
Symptoms: Interveinal chlorosis in older leaves, veins turn green while the rest of the leaf turns yellow. In severe cases of deficiency, leaf drop may occur.
Reason: Magnesium is a central component of chlorophyll, so its absence affects photosynthesis.
(f). Iron deficiency:
Ferrous or iron components are an important dietary component of small plants.
Symptoms: Interveinal chlorosis in young leaves, in severe cases the entire leaf turns yellow.
Reason: Unlike magnesium, iron is immobile in plants, so symptoms appear first on new growth.
(g). Calcium deficiency:
Calcium components are an important dietary component of small plants
Symptoms: Deformed, distorted, or curled leaves, often with brown spots on young leaves and shoot tips.
Reason: Calcium is essential for cell wall strength and membrane stability, and its deficiency leads to structural weakness.
(h). Zinc deficiency:
Zinc is an important nutrient for micronutrients
Symptoms: Small, small-shaped leaves with interveinal chlorosis on these leaves, often with pink or short internodes.
Reason: Zinc is essential for enzyme activity and hormone regulation in plants.
Brief introduction
Their identification and solution, that is, these points must be paid attention to, we often ignore them, although they do not require as much expenditure as the loss due to severe reduction in production.
Note
Special attention should be paid to ferrous sulfate in all types of areas
And in sandy areas, along with ferrous sulfate, calcium application should also be considered
