The role of rice cultivation in changes in atmospheric methane concentration and the Global Methane Pledge

Global Change Biology, 2023
Resumption of the increase in atmospheric methane (CH4) concentrations since 2007 is of global concern and may partly have resulted from emissions from rice cultivation. Estimates of CH4 emissions from rice fields and abatement potential are essential to

Long-term combined effects of tillage and rice cultivation with phosphogypsum or farmyard manure on the concentration of salts, minerals, and heavy metals of saline-sodic paddy fields in Northeast China

Soil & Tillage Research, 2022
Soil sodicity is a major ecological problem in the western Songnen Plain of Northeast China and rice cultivation is the main approach used to mitigate saline-sodic soils. However, rice cultivation alone may not be the most effective practice.

Soybean crop incorporation in irrigated rice cultivation improves nitrogen availability, soil microbial diversity and activity, and growth of ryegrass

Agriculture, Ecosystems & Environment. Applied Soil Ecology, 2022
Due to the genetic improvement of soybean cultivars more adapted to lowlands and to new drainage technologies, there has been a great insertion of soybean cultivation in rotation with irrigated rice in South America.

CH4 and CO2 emissions in water networks of rice cultivation regions.

Environmental Research, 2022
Rice cultivation regions have a high density of open water networks to meet the requirements of rice growth and production. These open water networks have a significant risk of carbon (C) emissions due to agricultural production, but the C emissions from

Artificial selection in the expansion of rice cultivation

Theoretical and Applied Genetics, 2021
Gene distributions and population genomics suggest artificial selection of ghd7 osprr37, for extremely early heading date of rice, in the Tohoku region of Japan. The ranges of cultivated crops expanded into various environmental conditions around the world after their domestication.

Effects of mild alternate wetting and drying irrigation and mid-season drainage on CH4 and N2O emissions in rice cultivation.

Science of the Total Environment, 2020
Rice, one of the major sources of CH4 and N2O emissions, is also the largest consumer of water resources. Mild alternate wetting and drying (AWD) irrigation is widely adopted to save irrigation water resources and maintain rice production, but its ...

Rotavation and Rice Cultivation

Madras Agricultural Journal, 1953
It is a known fact that the low yields of irrigated paddy are in a large measure traceable to late sowings and the same may also be said in the case of this State where predominantly rice growing areas exist and the vagaries of the monsoon do not allow the fields being got prepared for the timely sowings.
