IITAAgResults[Farmers' guide to management of aflatoxins in maize in Africa: pre-harvest and post-harvest recommendations]Farmers' guide to management of aflatoxins in maize in Africa: pre-harvest and post-harvest recommendations

Vietnam has pilot-tested a payment for forest environmental services (PFES) program in an effort to restore and protect forest areas, some of which have been severely degraded by the excessive cutting of trees by small-scale farmers planting annual crops on steep, sloping lands. The pilot program...

Alemayehu, A.Tamado, T.Nigussie, D.Yigzaw, D.Kinde, T.Wortmann, Charles S.[Maize–common bean intercropping to optimize maize-based crop production]Maize–common bean intercropping to optimize maize-based crop production

The recovery of a single application of leucaena (Leucaena leucocephala) leaf N (78 kg N ha−1) in a maize crop, the hedgerow and the top 10 cm soil of a leucaena alley cropping system was measured for 236 d through the use of 15N labeled residues. The leucaena-derived-N (LDN) was followed in the ...

Agroforestry systems involving leaf removal for animal fodder may result in rapid depletion of soil fertility. The purpose of this research was to determine if the effects of leaf removal on soil fertility parameters and maize yield in aLeucaena leucocephalaalley cropping system could be reversed...


Wendt, J.W.Jones, R.B.Bunderson, W.T.Itimu, A.O.[Leucaena + maize alley cropping in Malawi; part 2: residual P and leaf management effects on maize nutrition and soil properties]Leucaena + maize alley cropping in Malawi; part 2: residual P and leaf management effects on maize nutrition and soil properties

Maintaining indigenous nutrient supply and positive nutrient balances are key factors in sustaining rice yields. Irrigation systems act as conveyers for water, sediments and nutrients throughout landscapes, especially in mountainous, cultivated tropical areas where erosivity is usually high. Cont...


Slaets, J.I.F.Schmitter, Petra S.Hilger, T.Hue, D.T.T.Piepho, Hans-PeterVien, T.D.Cadisch, Georg[Sediment-associated organic carbon and nitrogen inputs from erosion and irrigation to rice fields in a mountainous watershed in Northwest Vietnam]Sediment-associated organic carbon and nitrogen inputs from erosion and irrigation to rice fields in a mountainous watershed in Northwest Vietnam

Composite agricultural systems with permanent maize cultivation in the uplands and irrigated rice in the valleys are very common in mountainous southeast Asia. The soil loss and fertility decline of the upland fields is well documented, but little is known about reallocation of these sediments wi...


Slaets, J.I.F.Schmitter, Petra S.Hilger, T.Vien, T.D.Cadisch, Georg[Sediment trap efficiency of paddy fields at the watershed scale in a mountainous catchment in northwest Vietnam]Sediment trap efficiency of paddy fields at the watershed scale in a mountainous catchment in northwest Vietnam

Aspergillus flavus induced ear rots and subsequent contamination of maize (Zea mays L.) by aflatoxin is a serious food safety issue, especially in developing countries where the crop is mostly cultivated by smallholder famers for own consumption and income generation. A better understanding of th...


Garrido-Bazan, V.Mahuku, George S.Bibbins-Martinez, M.Arroyo-Bacerra, A.Villalobos-López, M.A.[Dissection of mechanisms of resistance to Aspergillus flavus and aflatoxin using tropical maize germplasm]Dissection of mechanisms of resistance to Aspergillus flavus and aflatoxin using tropical maize germplasm

Agricultural extension to improve yields of staple food crops and close the yield gap in Sub-Saharan Africa often entails general recommendations on soil fertility management that are distributed to farmers in a large growing area. Site-specific extension recommendations that are better tailored ...
