Nutrient Deficiency Symptoms - Soil Science Oneliner
1. Dieback of citrus is due to deficiency of Copper (Cu).
2. Sickle leaf disease occurs due to deficiency of phosphorus.
3. Due to Calcium deficiency failure of terminal bud caused.
4. Yellow disease of tea is due to Sulphur deficiency.
5. Top sickness of tobacco is due to Boron deficiency.
6. Little leaf of cotton is due to Zn deficiency.
7. Pollen sterility in wheat is due to Boron deficiency.
8. Excess vegetative growth is due to supply of excess Nitrogen.
9. Whip-tail of cauliflower is due to Mo deficiency.
10. Deficiency symptoms of N,P,K,Mg and Mo appears in older leaves.
11. Deficiency symptoms of Fe,Mn,Cu,S appears on new leaves.
12. Deficiency symptoms of Zn appear on both old and new leaves.
13. Purple colour in leaves is due to deficiency of Phosphorus deficiency.
14. Zn toxicity is reduced by addition of Super phosphate.
15. Condition when crop required more of given nutrient yet shows no deficiency symptoms is called as “Hidden Hunger”.
16. Sunflower is an indicator plant of Boron.
17. Osmotic regulation is maintained by Potassium.
18. Al & Si is also known as Ballast element.
19. Functional nutrients are 21 (17 essential + 4 beneficial).
20. Sodium (Na) is most important element for deflocculation of soil.
21. Calcium (Ca) is important for flocculation of soil.
22. Potassium is useful to increase disease resistance in plant.
23. Nutrient mobility concept was given by ‘R.Bray’.
24. Concept of functional nutrient was given by ‘D.J.Nicholas’.
25. Mycorrhiza is most suitable for the absorption of Phosphorus.
26. Nutrient index concept is introduced by ‘Parker’.
27. Reclamation disease is due to deficiency of Copper.
28. Master nutrient of oilseed is Sulphur.
29. Indicator plant for phosphorus deficiency is mustard.
30. Mg is responsible for activation of RUBP (Rubisco) and germination of pollen.
31. Zn is involved in Auxin production.
32. Mo is needed for synthesis of ascorbic acid.
33. Cl is used as nitrification inhibitor.
34. K is essential for tuber crops.
35. Phosphorus is also known as ‘Key of Life’.
36. Phosphorus is helpful for anti-lodging of plants.
37. Potassium is also known as Traffic Police Man.
38. White bud in maize is due to Zn deficiency
39. Excess of B Nutrient in soil causes the Deficiency of - Mo
40. Energy Exchange elements - H,O.
