Abstract: Context Perennial forage grass species are often grown with limited water following establishment and rely on accessing water deep in the soil profile to survive. Aim This study aimed to characterise bermudagrass (Cynodon spp.) genotypes with rapid vertical root growth associated with post-establishment survival. Methods Twelve bermudagrasses representing genotypes from erse climate zones in Australia were established in rhizotrons to analyse the stability in genotypic variation in root and shoot growth in winter and summer experiments. Genotypic rank of root length, leaf area, and root dry weight were consistent in both seasons. Key results Bermudagrass genotypes exhibited different traits correlated with root vertical growth rate and inconsistency of genotypic rank of shoot growth. During winter establishment, the rate of root depth development (RRDD) (r = −0.64) was correlated with the proportion of root length that became inactive, that was likely due to seasonal root death in winter conditions during summer establishment, RRDD was correlated with tiller appearance rate (r = 0.45) and root distribution to 10 cm depth (r = −0.62). Shoot dry weight was correlated with photosynthesis (r = 0.85) and transpiration (r = 0.79) in summer, but not in winter. RRDD (r = 0.75, winter and r = 0.77, summer) was correlated with drought resistance index, previously analysed under field conditions. Conclusions and implications Genotypes from the Mediterranean climates in Australia showed rapid growth of roots and shoots in both seasons and have the greatest potential for broader application for forage production in variable environments.

Abstract: The participation of youth in agricultural entrepreneurship (agripreneurship) is beneficial for the sustainable development of agrarian societies that are transitioning towards the commercialization of agriculture. Accordingly, we investigated the phenomena that motivate practicing young, small- and medium-scale agripreneurs to pursue their careers, using the Lao People’s Democratic Republic (Laos) as a case study. To achieve this, we applied narrative inquiry techniques to the accounts of 74 young Laotian agripreneurs regarding their entry into agripreneurship. This enabled us to identify and describe common and influential paradigms that were subsequently interpreted from the perspective of entrepreneurship and behavioral studies of career decision making to explain the influence of motivations on the young agripreneurs. Our study has shown that despite the characteristics that set agripreneurship in Laos apart from entrepreneurship in general, commonly identified typologies of entrepreneurial motivation, particularly income, extrinsic benefits and emotional paradigms also motivate Lao youth to become agripreneurs. The application of narrative inquiry has revealed the emphasis some practicing agripreneurs in Laos place on the attainability of their career, which resulted in its practice by both opportunity-driven and necessity-driven entrepreneurs, with implications for the sustainable development of other countries in transition to commercial agriculture.
