This leaflet is a summary of an experiment conducted to explore the deficiency symptoms in Teff.

The experiment took place in a green house using 3 litre pots, filled with perlite. Each nutrient was tested at three levels: zero, low and optimal level.

The treatments were based on the nutrient omission method where all but one nutrient was omitted at a time. The nutrients that were tested were N, P, K, S, Ca, Mg, Fe, Zn, Mn, Mo and Cu.

The application rates of each nutrient were none or “zero concentration” of the tested nutrient, “low concentration” – contains 10% of what is considered adequate concentration of the tested element – and adequate “optimal concentration” of the tested element.

The optimal nutrient solution was derived from the original protocol developed by Hoagland and Arnon (1938), where a typical growth solution consisting of the essential macro-elements: N, K, P, Ca, Mg and S; and micro-elements: a soluble form of Fe, B, Cu, Mn, Ni, Zn, Mo, Cl.

The results are summarised in the leaflet.
