Abstract
Fractionation of forage legume crops can make a protein-rich feed available for monogastric animals. The aim of the current study was to assess the effect of fractionation method, leaf stripping or juice production, in lucerne (Medicago sativa) on protein yield in low-fibre fractions. We established field trial with replications on two lucerne varieties in Menemen, Turkey, in 2018. At first cut in 2019 whole plant and six different fractions were processed and sampled. Across varieties, juice, leaves and leaf juice yields accounted for 45%, 53% and 24% of the whole plant dry matter yield, respectively. Crude protein content was higher in leaf juice (26%) than whole plant juice (23%) and the content in leaves differed between the varieties (22% and 27%). Leaf stripping separated a higher proportion (on average 70%) of the total crude protein in the plant than juice production (on average 55%). The effects of variety, harvesting time and number of cut need further investigation.

This paper draws on network science and uses a Social Network Analysis to improve our understanding of how the implementation of no-till in England is influenced by farmers' social networks. No-till is a low disturbance farming practice with potential to benefit soil health, the aquatic environment and farm economy, but is currently only implemented at a small scale in Europe. Interpersonal networks are important for farmers and influence farmer learning and decision-making and farmers often view each other as their main source of information. In this study, the social networks of 16 no-till farmers in England were mapped and semi-structured interviews carried out to assess the link between farmer network characteristics and the implementation of no-till in England. We also aimed to improve our understanding of the nature and extent of knowledge exchanged within farmer networks and their spatial and temporal dynamics. Our findings suggest that intermediary farmers had an important role in increasing the information flow and knowledge exchange between the different clusters of the no-till farmer network. These intermediaries were also the biggest influencers as they were often no-till farmers with a high level of experiential knowledge and viewed as important sources of information by other farmers. No-till farmer networks were geographically distributed as the farmers preferred to discuss farming practices with similar minded no-till farmers rather than local conventional farmers who did not understand what they were trying to achieve. Therefore, online communication platforms like social media were important for communication. We question the role of formal extension services in supporting farmers with innovative practices like no-till and suggest that advisors should strive to improve their understanding of these well-developed information networks to enable a more streamlined and efficient information diffusion.
