Do commercial biological and chemical products increase crop yields and economic returns under smallholder farmer conditions? por Jefwa, J.M., Pypers, Pieter, Jemo, M., Thuita, Moses N., Mutegi, E., Laditi, M.A., Faye, A., Kavoo, A., Munyahali, W., Herselman, L., Atieno, M., Okalebo, J.R., Yusuf, A., Ibrahim, A., Ndung’u-Magiroi, K.W., Asrat, A., Muletta, D., Ncho, C., Kamaa, M., Lesueur, Didier

“…Except for tissue cultured bananas, the effect of arbuscular mycorrhizal fungal (AMF) inoculants was less evident with optimal yield of legumes realized with co-inoculation with P solubilizing bacteria and when supplemented with inorganic fertilizer such as DAP. Other products containing Trichoderma or Bacillus spp. improved growth under field conditions, soil-dependent growth improvements of over 40% in tissue culture bananas. …”

Arbuscular mycorrhizal fungal communities in subSaharan Savannahs of Benin, West Africa, as affected by agricultural land use intensity and ecological zone por Tchabi, A., Coyne, Danny L., Hountondji, F.C.C., Lawouin, L., Wiemken, A., Oehl, F.

“…We conclude that the West African savannas contain a high natural AM fungal species richness, but that this natural richness is significantly affected by the common agricultural land use practices and appears not to be quicklyrestored by fallow.…”

Does the enhanced P acquisition by maize following legumes in a rotation result from improved soil P availability? por Pypers, Pieter, Huybrighs, M., Diels, J., Abaidoo, Robert C., Smolders, E., Merckx, Roel

“…This study assessed the mechanism of this positive rotational effect in terms of soil P availability using a greenhouse trial with large volume (74 l) containers. The rotation effect was analysed in relation to PR application, previous legume growth and incorporation of the legume residues. …”

Trade-offs related to agricultural use of antimicrobials and synergies emanating from efforts to mitigate antimicrobial resistance por Wieland, Barbara, Grace, Delia, McDermott, John J., Magnusson, Ulf, Waage, Jeff, Fèvre, Eric M., Chadag, Vishnumurthy Mohan, Schillinger, Dieter

“…This evidence will then help to define and evaluate interventions needed to achieve development outcomes and to sustainably contain the risks around AMR. Directly linked are important synergies in such that improving husbandry and strengthen disease prevention would promote more productive and sustainable production systems, while at the same reducing need for use of antimicrobials. …”

Changes in fermentation and biohydrogenation intermediates in continuous cultures fed low and high levels of fat with increasing rates of starch degradability por Lascano, Gustavo J., Alende, Mariano, Koch, L.E., Jenkins, Thomas C.

“…The objective of this study was to compare accumulation of biohydrogenation intermediates causing milk fat depression, including conjugated linoleic acid (CLA), when corn with low or high Kd were fed to continuous cultures. Diets contained (dry matter basis) 50% forage (alfalfa pellets and grass hay) and 50% concentrate, with either no added fat (LF) or 3.3% added soybean oil (HF). …”
