Summary: This study used genotyping-by-sequencing (GBS) to evaluate agronomic traits and phenolic compounds in 96 sorghum genotypes, and conducted genome-wide association studies (GWAS) to identify the genetic basis of biomass-related traits. The research found six major phenolic compounds in sorghum biomass. Additionally, 40 significant single-nucleotide polymorphisms (SNPs) associated with heading date, plant height, dry yield, and phenolic compounds were identified. The findings highlight the potential value of sorghum as a biomass resource and the possibility of selecting sorghum genotypes with reduced phenolic contents for use in the bioindustry.

Summary: This study characterized the spatial and temporal variation of the target population of environments (TPE) for sorghum in the United States using the APSIM-sorghum model. The results showed that as the intensity of environmental stress increased, there was a clear reduction in grain yield. The study also identified different water and heat stress patterns and their impact on sorghum yield, which can be used in breeding programs to improve genetic gains and facilitate collaboration between breeders, agronomists, and farmers.

Summary: This study assessed the effects of rainwater harvesting and different rates of Leucaena leucocephala biomass on soil moisture content, rainwater use efficiency, and stover and grain yields in sorghum. The results showed that tied contour and infiltration pits significantly increased soil moisture content, and higher Leucaena biomass application rates also increased soil moisture content. All Leucaena biomass application rates significantly increased grain and stover yields, and rainwater use efficiency also increased with Leucaena biomass application rates. The study suggested that tied contour and infiltration pits are better adaptive mechanisms for drought-prone areas and can be combined with Leucaena biomass to improve sorghum production.

Summary: In coastal saline lands, where organic matter is scarce and saline stress is high, the intervention of organic acid from biological materials can improve soil conditions and increase the forage output. The study found that the citric acid-pine needle composite effectively reduced soil salinity and increased nutrient content, leading to improved growth and physiological performance of sweet sorghum. The fulvic acid-pine needle composite also had positive effects on plant growth at later stages.

Summary: This experiment compared 12 different cytoplasmic male sterile sorghum genotypes and their respective male fertile lines to assess the frequency of hybridization and seed set. Results indicated significant differences in interspecific hybridization frequency among the sorghum genotypes, and pollen fertility in sorghum reduced the rate of hybridization. Hybridization rates also varied across study environments. These findings are helpful for developing gene flow mitigation strategies and suggest that gene flow could be reduced by selecting appropriate seed parents for sorghum hybrids.

Summary: The use of treated water for agriculture can promote sustainable irrigation development and ensure food sovereignty. This study evaluated the feasibility of subsurface drip irrigation (SDI) and reclaimed water (RW) for forage production in a warm arid region, comparing them with traditional drip irrigation (DI) and conventional groundwater (CW). The results showed that using RW for irrigation without additional fertilizers produced a forage yield of 200 tons/ha/year. Soil fertility increased and risk parameters returned to normal levels after the rainy season. RWSDI was found to have the highest water use efficiency, requiring 34% less water compared to RWDI. This study highlights the importance of considering nitrate elimination rates and establishing new salinity tolerance levels for agricultural reuse in arid regions.

Summary: The study investigates the impact of soil and lightning NOx emissions on the trend of OMI NO2, finding that improvements in estimating soil NOx emissions have led to a slowdown in the reduction of total NOx emissions. With background emissions becoming relatively larger and inter-annual variations uncertain, relying solely on NO2 VCDs is insufficient to discern trends in anthropogenic emissions.

Summary: This study utilized a modeling approach to estimate plant greenness in tidal wetlands within the San Francisco Bay Area, finding that the approach accurately estimated plant greenness but with larger errors in more dynamic restored wetlands, particularly at early post-restoration stages. The modeled EVI can be used as an input variable in greenhouse gas models for estimating carbon sequestration and gross primary production. Future research can further develop this strategy by assessing restoration and management effects on wetland phenological dynamics and incorporating the entire Sentinel-2 time series within Google Earth Engine.

Summary: Regenerative agriculture aims to improve soil health and promote biodiversity while producing nutritious food profitably. By implementing multiple regenerative practices, soil quality, water infiltration rate, microbial quantity, plant biomass, and invertebrate diversity can be increased while reducing pest populations and improving orchard profits. The success of regenerative farms lies in the combination of multiple practices into a functional system rather than relying on a single practice.
