HORTICULTURE

Detailed explanation-1: -Cause: Nitrogen promotes green, leafy growth and deficiency results in yellowing and stunted growth.

Detailed explanation-2: -Nitrate serves plants as a nutrient and is an important growth factor. It is absorbed from the soil through the roots and helps build organic compounds such as proteins and nucleic acids. Nitrite (NO2-) is an intermediate product in the conversion of nitrate and is formed with the help of microorganisms and enzymes.

Detailed explanation-3: -This happens because plants close their aqua pores in response to an N lack. Consequently, water and nutrient transportation to shoots is restricted. Under severe nitrogen deficiency – without water, nutrition, cell-building materials, poor photosynthesis and no energy as a result – crops will eventually die.
