Effect of bio‐fertilization and edapho‐climatic conditions on chickpea nodulation, grain yields, and seed protein in a Mediterranean context: a meta‐analysis approach

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract Chickpeas (Cicer arietinum L.) serve as a protein‐rich staple, particularly in Mediterranean countries, where they are often grown in marginal and water‐stressed areas. This meta‐analysis synthesized evidence from peer‐reviewed publications across Mediterranean countries to assess how chickpea rhizobial inoculation influences chickpea ...

A Bibliometric‐Based Review of Biochar for Salt‐Affected Soil Restoration: Mapping Research Trends and Future Directions

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT In recent years, biochar has been studied for its range of applications. Recognized by the IPCC as a key Carbon Dioxide Removal (CDR) strategy, it also stands out as an important tool for reclaiming degraded lands, including vast global areas affected by salinity, such as those in China, India, and Australia.
