Agronomic evaluation of unacidulated and partially acidulated Chilembwe rockphosphates for clover seed production

Autor: Haque, I. Lupwayi, N.Z. Ssali, H.

Phosphorus (P) is required to improve soil fertility for food and feed produciton in sub-Saharan Africa, but the high cost of conventional, water-soluble P fertilizers limits their use by resource-poor farmers. Rockphosphates are a low-cost alternative. The effectiveness, in terms of seed product...

Soil micronutrient contents and relation to other soil properties in Ethiopia

Autor: Haque, I. Lupwayi, N.Z. Tadesse, T.

Alfisols, Vertisols, Inceptisols, Aridisols, Mollisols, and Entisols were sampled (0-30 cm) from 32 locations across Ethiopia. The soils were analyzed for copper (Cu), zinc (Zn), manganese (Mn), and iron (Fe) contents using 0.005 M diethylene triamine pentaacetic acid (DTPA), 0.05 M hydrochloric ...

Leucaena hedgerow intercropping and cattle manure application in the Ethiopian highlands. III. Nutrient balances

Autor: Lupwayi, N.Z. Haque, I.

Balances between nutrients applied or mineralized and nutrients removed in maize grain and stover were calculated in a hedgerow intercropping experiment in which Leucaena leucocephala and L. pallida prunings and cattle manure were applied. Hedgerow intercropping (also called alley cropping) is an...

Improved soil fertiliy increases nodulation of Phaseolus beans

Autor: Lupwayi, N.Z. Mkandawire, A.B.C.

The effect of soil fertility on the response of field beans (Phaseolus vulgaris L.) to inoculation with Rhizobium leguminosarum bv. phaseoli was investigated at five sites in northern and central Malawi. A split-plot design consisting of (a) un-inoculated plants, (b) inoculated plants and (c) N-f...
