Correct Answer - Option 1 : Nitrate
The correct answer is Nitrate.
- Nitrogen is the most abundant element in our atmosphere.
- It is an important component of many essential structural, genetic and metabolic compounds in plant cells.
- Roots take up nitrogen in their inorganic forms, nitrate (NO3-) and ammonium (NH4+) ions.
- Nitrogen is the nutrient that normally produces the greatest yield response in crop plants, promoting rapid vegetative growth and giving the plant a healthy green colour.
- It is also a major component of amino acids, the building blocks of proteins. Without proteins, plants wither and die.
- Plants lacking nitrogen have very slow growth and look weak and stunted.
