TL;DR: In this article, a robust yield gap analysis for 10 countries in sub-Saharan Africa using location-specific data and a spatial upscaling approach reveals that, in addition to yield gap closure, other more complex and uncertain components of intensification are also needed, i.e., increasing cropping intensity and sustainable expansion of irrigated production area.
Journal ArticleDOI
Grapevine bud fertility and number of berries per bunch are determined by water and nitrogen stress around flowering in the previous year
TL;DR: The results show that the maximum yield that can be reached in season 2 is determined during the critical period of season 1 and they provide clues to estimate it and may help grape growers to adapt their practices to ensure a sufficient maximum yield for season 2.

Can Bangladesh produce enough cereals to meet future demand
Jagadish Timsina,Joost Wolf,Nicolas Guilpart,L.G.J. van Bussel,Patricio Grassini,J. van Wart,Akbar Hossain,H. Rashid,Saiful Islam,M.K. van Ittersum +9 more
TL;DR: The degree to which Bangladesh can be self-sufficient in terms of domestic maize, rice and wheat production by the years 2030 and 2050 is assessed by closing the existing gap (Yg) between yield potential (Yp) and actual farm yield (Ya), accounting for possible changes in cropland area.
Journal ArticleDOI

TL;DR: This study produced the first spatially explicit, coherent and complete maps of the rootable depth and RZ-PAWHC of soil in SSA, and developed and parameterised functions, rules and criteria to evaluate soil water retention at field capacity and wilting point, the soil fine earth fraction from coarse fragments content and, for maize,The soil rootability (relative to threshold values) androotable depth.
Journal ArticleDOI
Estimating yield gaps at the cropping system level.
TL;DR: A framework to estimate cropping system yield potential and yield gap was developed and opportunities to increase crops system annual yield were identified.
