FLOURISH - Boron is a Borax ( Sodium tetraborate ) contains 10.5 %
Boron is required for cell division and extension. It is essential for pollen tube
growth which affects seed/fruit set and hence yield.
Rice: Young leaves are deformed and growing points undergo drying and
Wheat: Boron deficiency causes thickening of stems and leaves, shortened
internodes and reduced flowering and seed formation.
Pulses: Stem thickens, growing points die, leaves become slightly chlorotic
and mottled, seed setting is reduced.
Boron should be applied to a deficient soil as borax @ 10 kg/ha through
broadcasting at the time of planting rice, wheat or pulses.
It can also be applied through foliar spray as 0.5 % solution of borax 15 days
after planting and at flower initiation stage.
