Describe in brief about the Boron  - Micronutrients 

Boron is required in extremely small amounts in the range of 0.01 to 1.0 ppm. The actual amount may vary from crop to crop but seldom exceeds 33-56 kg of borax per hectare when broadcast (spread in the form of a shower from above) or 4.5 kg when applied in the rows.

  • It influences cell development by affecting the polysaccharide formation and regulates Trans location of sugars across membranes.
  • It affects the intake of calcium and its efficient utilisation by the plant.
  • It acts as a regulator of the K+/Ca2+ ratio.
  • It is intimately related to the absorption of nitrogen and is necessary in cell division.
  • It appears to be fixed in plant tissues so that it cannot move to parts where it is most needed. As a result continuous supply is needed to meet plant requirement.
  • If plant contains a large supply of potassium there is a boron deficiency.
