Climate change and agricultural productivity in Sub-Saharan Africa: a spatial sample selection model

European Review of Agricultural Economics, 2013

We control for localized spatial correlation in unobserved disturbances affecting both the selection to plant cereals as well as in the resulting conditional yield response. We find that cereal yields across Sub-Saharan Africa will decline with increasing temperatures resulting from global climate change, and that failing to control for sample selection leads to underestimation of these adverse effects.

The interaction between vegetative growth and reproductive development was examined. Daily net photosynthesis and the related assimilate supply were calculated by a simulation model. The actual dry matter accretion of vegetative and reproductive organs was derived from non-destructive measurements of organ dimensions and subsequent convertion to dry matter by statistical relations. Integrated over the total period of investigation, dry matter accretion derived either from the calculated assimilate supply or from ac~;ual measurements agreed well. However, a significant discrepancy appeared in the dynamic resolution where apparent periods of assimilate surplus were followed by periods of apparent shortage of assimilates. In this respect, the regulation of temporary storage and subsequent remobilization of assimilates is studied in relation to source-sink interactions. A hypothesis is formulated that relates the dynamics of fruit growth to assimilate supply and the sink activity of individual fruits.

Effects of nitrogen supply on tillering dynamics and regrowth of perennial ryegrass populations

Three subsequent conditions were used: 1) two steady-state plant nitrogen concentrations (0.027 and 0.042 g N.g DM" 1), 2) changing nitrogen availability to zero, 3) changing nitrogen availability to a supra-optimal level. Populations were grown in monocultures and mixtures to investigate the correlation between monoculture and mixture performance. The highest yielding population yielded 40 % more cut herbage than the lowest yielding population. Its nitrogen uptake was 29 % higher and its organic nitrogen concentra tion was between 5 and 8.5 % lower. Population differences in mixtures were larger, but population order remained the same. It was therefore concluded that selection of populations for regrowth characteristics can best be done in mixtures. Stopping nitrogen application re duced tiller density and assimilate allocation to shoots. Both were restored to more than the original values after changing to a supra-optimal nitrogen availability. Analysis of tillering in terms of leaf appearance and site filling showed a negative genetic correlation between the two factors. A simulation model was developed to evaluate the relative importance of tiller density, leaf expansion and assimilate partitioning for regrowth.
