\textbf{Abstract}
\begin{abstract}
\normalsize{
Increasing temperatures due to climate change, saline soils due to lack of water and decreasing soil fertility due to missing crop rotations are some of the major problems farmers in Central Asia are faced with. Additionally, many farmers experience food insecurity, as governments tens to support cultivation of cash crops for export, rather than crop diversification; which in turn is intensifying the problematic agricultural and nutritive situation. Cultivation of mungbean as a catch crop could be part of a strategy to counteract this development, since symbiotic nitrogen fixing bacteria on mungbean roots may increase soil fertility by enhancing the nitrogen content in the soil and can hence contribute to an increase in yield of following crops. Thereby mungbean itself can also serve as food or fodder locally. 



Goals of this interdisciplinary research collaboration with partners from Uzbekistan, Pakistan, Taiwan and Germany on mungbean were: (i) to improve the livelihood of farmers and (ii) to identify heat, drought, salinity and yellow mosaic virus tolerant genotypes, and (iii) to integrate the best performing genotypes into crop rotations of dryland farmer, enabling them to develop also in adverse ecological conditions. 



The project is coordinated by AVRDC - The World Vegetable Centre in Taiwan, being also responsible for breeding and provision of seeds.  In Uzbekistan, yield performance and virus resistance of various genotypes will be measured at three locations, whereas in Pakistan the effect of plant growth promoting rhizobacteria (PGPR) and rhizobia on salinity tolerance is analyzed. In a pilot scale study, inoculation with PGPR strains containing ACC-deaminase, like \textit{Pseudomonas fluorescens}, and \textit{Rhizobium} performed significantly better by improving growth, nodulation and physiological parameters of mungbean as compared to sole inoculation of either \textit{Rhizobium} or PGPR strains under salt"=affected conditions. Mungbean's contribution to soil fertility will be examined by determining the impact of abiotic stress factors on the biological nitrogen fixation. Preliminary pot trial results indicate the likelihood of identifying genotypes for field application with better stress tolerance and improved nitrogen fixation, fostering the yield of subsequent crops.}
