Tomato plants are highly valued horticultural crops, Tomato crops are highly susceptible to nutrient deficiencies, which can adversely affect both yield and quality. Proper nutrient management is essential to ensure healthy plant growth, vibrant fruit development, and increased productivity.
Understanding Nutrient Deficiency in Tomato Plants
Calcium Deficiency in Tomatoes
- Fruit Cracking
- Blossom End Rot: Dark, sunken spots at the blossom end of the fruit.
- Slower plant development.
- Leave Curling upwards or inward.
- Flower and Fruit Drop: Premature shedding in severe cases.
Management
Use Katyayani Calcium Nitrate:
- Soil Application: Apply 5- 10 g per Acre.
- Foliar Spray: 3 g per liter of water
Magnesium Deficiency
Symptoms
- Interveinal Chlorosis: Yellowing between leaf veins, starting with older leaves.
- Leaf Margins: Browning and scorching edges.
- Stunted Growth: Slower plant development.
- Premature Defoliation: Early leaf drop in severe cases.
Management
Use Katyayani Epsom Salt:
- Foliar Spray: Dissolve 10-15 g per liter of water. Apply 3-4 sprays per crop.
- Soil Application: Use 2-3 kg per acre
Nitrogen Deficiency in Tomatoes
Symptoms:
- Pale, yellow leaves
- Stunted growth and poor fruiting
Management:
Potassium Deficiency in Tomatoes
Symptoms:
- Brown spots on leaf edges
- Weak stems and poor fruit development
Management:
- Spray- 00:00:50 - 5 gm / liter water
- Soil Application- 1 kg / Acre
Sulfur Deficiency
Symptoms
- Yellowing Leaves: Starting from younger leaves.
- Thin, Brittle Leaves: Curling downward.
- Stunted Growth: Slower development.
- Purple Veins: Reddish-purple veins in severe cases.
Management
Use Katyayani SULVET:
- Soil Application: Sulphur 80% - 750-1000 g per acre. OR Sulphur 90% - 3-6 kg / acre
Boron Deficiency
- Symptoms: Cupped or brittle leaves, terminal chlorosis, and internal browning in fruits.
- Management: Foliar spray of Katyayani Boron 20%, 1-1.5 g per liter of water.
Copper Deficiency
- Symptoms: Interveinal chlorosis, wilting, and misshapen fruits.
- Management: Apply Katyayani Copper Sulphate, 400 g per acre.
Iron Deficiency
- Symptoms: Interveinal chlorosis- especially on younger leaves.
- Management: Use Katyayani Iron EDTA, 1-2 g per liter for foliar spray.
Manganese Deficiency
- Symptoms: Chlorosis with necrotic spots and stunted growth.
- Management: Apply Katyayani Manganese Sulphate, 1 kg per acre.
Zinc Deficiency
- Symptoms: Compressed plant appearance, reduced fruit size, and leathery leaves.
- Management: Spray Katyayani Zinc EDTA 12%, 100 g in 150-200 liters of water per acre.
Frequently Asked Questions
Q. What causes calcium deficiency in tomatoes?
A. Uneven watering, acidic soils, and overuse of nitrogen fertilizers are common causes.
Q. How can I prevent blossom end rot in tomatoes?
A. Ensure consistent watering, use calcium-rich fertilizers, and maintain proper soil pH.
Q. How do I identify magnesium deficiency in tomatoes?
A. Look for yellowing between veins of older leaves and browning of leaf edges.
Q. Why are my tomato plant leaves turning yellow?
A. Yellowing may indicate nitrogen, magnesium, or sulfur deficiency despite regular watering.
Q. Can calcium nitrate and magnesium sulfate be mixed?
A. No, apply them separately to avoid chemical reactions that reduce effectiveness.
