Other claims from this paper (8)

Intervention effect In both the pot and field experiments, tef grain yield increased with phosphorus up to 6 mg L−1 and declined at 12 mg L−1.
Intervention effect In the pot experiment the decline in tef grain yield at 12 mg L−1 P was precipitous and significant.
Intervention effect In the field experiment the decline in tef grain yield at 12 mg L−1 P was gradual and statistically insignificant.
Intervention effect In the pot experiment, tef grain yield increased with potassium up to 40 mg L−1.
Intervention effect The effect of potassium concentration on tef was seen only in grain yield.
Intervention effect Potassium concentration had no effect on the size of the other plant organs of tef.
Intervention effect In the field experiment, tef grain yield was highest at 80 mg L−1 K but not statistically different from that at 40 mg L−1.
Intervention effect The effect of potassium on tef growth was apparent only at maturity and not at flowering.
