Soil Sulfur Deficiency Indices Assessment for Wheat Production in Ethiopia

Assefa Menna · Asian Journal of Soil Science and Plant Nutrition · 2017

Sulfur (S) deficiency is becoming one of the soil health challenges in the Ethiopian crop production systems. However, visual identification of its deficiency, especially in cereals is difficult, because the symptoms are nearly identical with those of nitrogen. Hence, deficiency...

Assessment of Sulfur Deficiency in Soils through Plant Analysis in Three Representative Areas of the Central Highlands of Ethiopia-IV

Assefa Menna · Journal of Agriculture and Ecology Research International · 2017

Field survey was conducted in Arsi(Ar), East Shewa(ES) and Oromia Liuu(OL) zones in 2012-15 cropping seasons, aimed at assessing sulfur(S) status of soils through plant analysis. The general information on land-use, soil types, were collected using semi-structured questionnaire t...

Estimation of Optimum Rate of Sulfur for Application in Soils for Wheat Production in Ethiopia –III

Assefa Menna, Johnson M. R. Semoka, Tekalign Mamo & Nyambilila Amuri · Journal of Agriculture and Ecology Research International · 2016

Six on-farm experiments were conducted in 2013/2014 seasons, in the Central Highlands (CHLs) of Ethiopia, with the main aim of estimating optimum sulfur rate for wheat. The treatments were, 4-levels of S(S0 =0, S1 =5, S2 =10, and S3 =20 kg S/ha); 2-levels of N(N0 =0, N =N1 =69 kg...
