Nano Chelated Iron and Boron Effect on Their Rates of Absorption and Transport by Moringa Plant

An experiment was carried out under a plastic house during 2019/2020 in Al-hindiya Herticaullare Station, Kerbala Province, Iraq. Seeds of Moringa Were sown in black polyethylene bags 5 kg soil capacity. Factorial experiment within Completely Randomized Design (C.R.D) with three replicates was adopted. The aim was to assess the effect of three Levels of the nano chelated Fe i.e. 0 ,180 and 360 mg. L-1, and Four Levels of B i.e. 0, 25 ,50 and 75 mg. L-1 spraying either once or twice – on the Fe and B rates of absorption and transport.
