Tef (Eragrostis tef) Responses to Phosphorus and Potassium Fertigation under Semi-Arid Mediterranean Climate

Tef (Eragrostis tef (Zucc.) Trotter) is an annual small grain, panicle bearing, C4 cereal crop native to Ethiopia, where it a major staple food. The objectives of the present study were characterize responses two genotypes escalating phosphorus (P) and potassium (K) levels determine optimum range for P K at which performance maximized. Two experiments carried out in Gilat Research Station, each testing different (405B 406W), one experiment pots controlled conditions, other field. In both experiments, highest grain yield increased until 6 mg L−1 P, declined 12 P. decline was precipitous significant pot experiment, gradual statistically insignificant field experiment. 40 K, with no decrease thereafter. effect concentration only seen not size plant organs. 80 but from L−1. on growth apparent maturity flowering.
