Effect of Iron chelate consumed and non-consumed tea on corn plant

Abstract

The factorial experiment was conducted during autumn season 2009, from 10th July to 29th September to study effect of three Fe-chelate comp- ounds and two types of tea residue (consumed and non consumed tea) each of them with 5 levels which equivalent (0 , 2.5 , 5 , 7.5 and 10 mg Fe Kg-1 soil) and their interactions on growth, iron and chlorophyll concentration in corn plant using completely randomized design with 3 replicates.The results indicated significant effect of type, levels of compounds and their interaction on total chlorophyll ,iron concentration in plant and dry weight the highest values of them (16.32 mg.g-1 dry matter , 136.86 µg.g-1 dry matter and 119.2 g.pot-1 were recorded from interaction treatments (Fe-EDTA*L5 , Fe-EDDHA 6% *L4 and 1% of consumed tea * L2) respectively.
