Abstract: Alternative water management practices for rice (Oryza sativa) production have been developed for water conservation purposes, such as the furrow-irrigated rice production system, which results in variable volumetric water content (VWC), temperature, and oxidation-reduction (redox) potential conditions. The spatial and temporal variations in environmental factors can affect greenhouse gas (GHG) emissions.

Abstract: Water management regimes influence greenhouse gas emissions in rice (Oryza sativa L.) production. The objective of this study was to quantify methane (CH4), nitrous oxide (N2O), and carbon dioxide (CO2) under direct-seeded conditions in the greenhouse to evaluate the effects of water regime on fluxes and growing-season-long emissions. Research was conducted during 2019 using a hybrid rice cultivar (RT 7311 CL) grown in a DeWitt silt loam (Albaqualf).

Abstract: The CIPK gene family plays a key role in plant development and in stress signal transduction. The orthologs for experimentally proven drought stress responsive CIPKs from rice was identified in maize and sorghum. A total of 49 genes from the three species were analyzed for their phylogenetic relationship, gene structure, expression level and tissue specificity upon drought stress.

Abstract: Rice (Oryza sativa L.) is one of the most important field crops after wheat in the world providing staple food to the millions. It is an indispensable source of calories for almost half of the population with in Asia. More than 90% of the world rice is produced and consumed in Asia, which is a native for 60% of the earth’s population.

Abstract: A two-year experiment was conducted in 2013 and 2014 to evaluate the effect of water management practices on methane (CH4) and nitrous oxide (N2O) emission, and grain yield from Louisiana rice fields. Three water management practices, including delayed flooding (DF), straighthead (SH), and intermittent flooding (IF), were evaluated. Seasonal cumulative CH4 emissions were lowest in IF treatment in both 2013 (125 kg CH4 ha-1) and 2014 (271 kg CH4 ha-1)

Abstract: Furrow-irrigation is a relatively new rice (Oryza sativa L.) production practice that results in large variations in nearsurface soil water contents along the long length of a furrow-irrigated field that may have major impacts on the ability to accurately measure and quantify greenhouse gas (GHG) emissions. The objective of this study was to evaluate the effects of tillage [conventional tillage (CT) and no-tillage (NT)], site position
