Does the combined application of organic and mineral nutrient sources influence maize productivity? a meta analysis por Chivenge, Pauline P., Vanlauwe, Bernard, Six, Johan

“…The greater yield responses with ORs + N fertilizers than either resource alone were mostly due to extra N added and not improved N utilization efficiency because negative interactive effects were, most often, observed when combining ORs with N fertilizers. …”

Long-term effects of continuous direct seeding mulch-based cropping systems on soil nitrogen supply in the Cerrado region of Brazil por Maltas, A, Corbeels, Marc, Scopel, E., Oliver, R., Douzet, Jean-Marie, Silva, F.A.M. da, Wery, Jacques

“…These results indicate that even in the medium term (10 years), continuous DMC cropping has limited implications for N fertilization recommendations, since the extra soil N supply represents less than 20% of the common N fertilization dose for maize in the region.…”

Sustainable intensification of agriculture with sustainable irrigated agroecosystem services por Makin, Ian W., Manthrithilake, Herath

“…Future population growth and economic development means that the increasing demand for food must be expected to continue, and it is projected that intensified irrigated agriculture will have to provide about 60% of the extra food needed (World Bank, 2007). Yet, the expansion of irrigated areas has slowed, rates of productivity improvement are slowing, and water availability for irrigation is being constrained by alternate demands for water. …”

Estimates of genetic variances in Striga resistant extraearlymaturing maize populations por Badu-Apraku, Baffour

“…Breeders should maintain sufficient genetic variability in a population to ensure continuous advance from selection for a target trait. The extra-early-maturing Striga resistant/tolerant maize (Zea mays L.) populations, TZEE-W Pop DT STR (white) and TZEE-Y STR (yellow), have each gone through three cycles of S1 recurrent selection for improvement for grain yield, Striga resistance under artificial Striga infestation, and other desirable agronomic characters. …”

Large genetic diversity for fine-flavor traits unveiled in cacao (Theobroma cacao L.) with special attention to the native Chuncho variety in Cusco, Peru por Eskes, A., Rodríguez, C.A.C., Cruz Condori, D., Seguine, E., García Carrion, L., Lachenaud, P.

“…Chuncho beans, still largely employed as a bulk cocoa source, deserve to become fully processed as an extra-fine cocoa variety. The valorization of the numerous T. cacao sensory profiles in chocolates, raw beans and juices should substantially diversify and boost the fineflavor cocoa industry, this time based on the Matsigenka/Inca and not anymore on the Maya cocoa traditions.…”

Options for soil organic carbon maintenance under intensive cropping in the West African savanna por Diels, J., Lyasse, O., Sanginga, N., Vanlauwe, Bernard, Aihou, K., Iwuafor, E.N.O., Merckx, Roel, Deckers, J.

“…Based on calculations with the Rothamsted carbon model, this extra biomass translates into an increase in the topsoil carbon content of 0.33% C after 20 years. …”
