Biochar and nano biochar: Enhancing salt resilience in plants and soil while mitigating greenhouse gas emissions: A comprehensive review.

Salinity stress poses a significant challenge to agriculture, impacting soil health, plant growth and contributing to greenhouse gas (GHG) emissions. In response to these intertwined challenges, the use of biochar and its nanoscale counterpart, nano-biochar, has gained increasing attention. This comprehensive review explores the heterogeneous role of biochar and nano-biochar in enhancing salt resilience in plants and soil while concurrently mitigating GHG emissions.

Dry direct-seeded rice has higher energy and carbon production efficiencies without reducing economic benefits.

Background: Water and energy shortages and food security challenges associated with global warming are essential issues affecting human survival and development. Rice is one of the world's top three staple food crops. In the present study, the energy footprint (EF), carbon footprint (CF), energy production efficiency (EPE), carbon production efficiency (CPE), and economic benefit (EB) of dry direct-seeded rice (DSR), wet direct-seeded rice (WSR), and transplanted rice (TPR), respectively, were integrated and assessed.

Rice yield penalty and quality deterioration is associated with failure of nitrogen uptake from regreening to panicle initiation stage under salinity.

In recent years, the development and utilization of saline land for rice cultivation have effectively expanded grain productivity. Rice is a salt-sensitive crop, and the increasing salinity problem threatens rice yield and quality. Therefore, we conducted open field experiments to study the effect of salinity on different growth stages of rice.
