Reports concentrations of primary and secondary nutrients in the dry matter that were harvested at various times and the removal of the nutrients from an upland soil in the Ethiopian highland in part III. Part IV deals with the concentration and uptake of Na, Mn, Cu, Zn and Fe from the dry matter...

Intercropping maize & forage type cowpeas in the Ethiopian highlands: III. Concentration, macronutrient yields and crop residue quality. IV. Concentration, micronutrient yields and crop residue quality
This paper looks at the applicability of three management oriented simulation models that are being evaluated by the environmental Sciences Division at ILCA. Basically the three models (CERES-maize NITROSIM and SCUAF) have been designed to simulate crop growth and development and crop yields, as ...

The effects of Leucaena leucocephala and L. pallida prunings and cattle manure on maize nutrient uptake and yield were investigated in a hedgerow inter-cropping trial in the Ethiopian highlands. Hedgerow inter-cropping (also called alley cropping) is an agroforestry system in which trees are grow...
