Relationships of grain delta C-13 and delta O-18 with wheat phenology and yield under water-limited conditions
Stable carbon isotope composition (delta C-13) of dry matter has been widely investigated as a selection tool in cereal breeding programmes. However, reports on the possibilities of using stable oxygen isotope composition ...
Soil carbon stocks in conservation agriculture systems of Southern Africa
In view of the importance of soil carbon (C) and the scarce data on how conservation agriculture might influence its accumulation in Southern Africa this study presents data from 125 on-farm validation trials across 23 ...
Why Self-fertilizing Plants Still Exist in Wild Populations: Diversity Assurance through Stress-Induced Male Sterility May Promote Selective Outcrossing and Recombination
Climate change creates challenges for wild species, but plants have survived and adapted
to similar changes in their evolutionary past. Most plants were originally outcrossing, one theoretical
genetic reason being that ...
Diversity analysis of 80,000 wheat accessions reveals consequences and opportunities of selection footprints
Undomesticated wild species, crop wild relatives, and landraces represent sources of variation for wheat improvement to address challenges from climate change and the growing human population. Here, we study 56,342 ...
Yield gain due to fungicide application in varieties of winter wheat (Triticum aestivum) resistant and susceptible to leaf rust
In three independent experiments in Turkey and Kazakhstan, winter wheat germplasm with variable degrees of resistance to leaf rust was subjected to fungicide protection. The yield loss of genotypes susceptible to leaf rust ...
Soil salinity management on raised beds with different furrow irrigation modes in salt-affected lands
Mismanagement of irrigation water and the ensuing secondary salinization are threatening the sustainability of irrigated agriculture especially in many dryland regions. The permanent raised-bed/furrow system, a water-wise ...
Overcoming constraints of scaling: Critical and empirical perspectives on agricultural innovation scaling
Scaling is a ubiquitous concept in agricultural research in the global south as donors require
their research grantees to prove that their results can be scaled to impact upon the livelihoods
of a large number of beneficiaries. ...
Spearheading Development through Empowering Smallholder Farmers along Beef Cattle Value Chains: a Case of Goromonzi and Murehwa Districts, Zimbabwe
Smallholder beef subsector can potentially contribute to the nation’s development. The paper presents the
results of the value chain analysis of the beef sub sector in Zimbabwe. Data was gathered through cross
sectional ...
Photoperiod and vernalization response of wheat under controlled environment and field conditions
Characterization of large numbers of breeding lines for vernalization and photoperiod response in wheat is needed to enhance adaptation. A total of 20 wheat lines were evaluated for response to vernalization and photoperiod ...
Global crop improvement networks to bridge technology gaps
To ensure future food security, there is an urgent need for
improved co-ordination of agricultural research. While
advances in biotechnology hold considerable promise,
significant technology gaps exist that may reduce ...
