“…While a combination of in-furrow insecticidal application may be of benefit to growers, growers should consider manipulating sorghum hybrids and planting date when making decisions on the use of in-furrow applications of flupyradifurone. Historically, corn has been the main silage crop in the USA, although recent reports suggest that forage sorghum has the potential to produce large quantities of silage that can sustain dairy and feedlot beef cattle operations [22,23]. Therefore, more studies that aim to optimize biomass production of other types (e.g., silage, forage, sweet, and bioenergy) of sorghum by effectively suppressing M. sorghi infestations are needed across a wider geographical area.…”

Studies on the management of the invasive Melanaphis sorghi are essential to refining integrated pest management strategies against M. sorghi in forage sorghum in the USA. The objective of this study was to determine the impact of planting date (early planting and late planting) and in-furrow and foliar insecticide application of flupyradifurone, on M. sorghi infestation and forage sorghum yield in Tifton, Georgia and Florence, South Carolina, USA, in 2020 and 2021. Early planted sorghum supported slightly higher aphid density and severity of infestation as evident in the greater cumulative insect days values in the early planted sorghum at both Florence and Tifton in 2020 and 2021. A single foliar application reduced aphid infestations below the threshold level of 50 aphids per leaf. In contrast, in-furrow insecticidal application in selected plots at both locations significantly suppressed M. sorghi density to near-zero levels. Yield results in Florence in 2020 showed that sorghum yield was over 50% greater in early planted plots compared to late planted plots. Both insecticide treatments (foliar and in-furrow) resulted in significantly higher yield than untreated plots. These data indicate that early planting coupled with in-furrow and foliar insecticide applications can suppress M. sorghi infestations and improve silage production in forage sorghum in the USA.

“…Altered and nonfunctional playas demonstrate significantly reduced recharge and increased evaporative water losses relative to naturally functioning playas (Bolen et al, 1979;Bolen et al, 1989). The Ogallala Aquifer has historically beenand continues to be-pumped at a rate higher than recharge (Almas et al, 2004;Hornbeck & Keskin., 2014;Steiner et al, 2021). In some areas of Texas, the Ogallala Aquifer is now too depleted for any groundwater extraction, and those producers and municipalities have been forced to move or acquire water from elsewhere (Zellmer, 2007).…”

With roughly 3.9 million acres of wetlands, 2.3% of its total land area, Texas has the fifth largest wetland acreage in the United States. As of 1990, there was an estimated 52% reduction in the state's original wetland acreage, but there has been no recent assessment of statewide wetland loss or gain since then. Wetlands provide critical ecosystem services, including wildlife habitat, flood storage and control, aquifer recharge, water quality improvement, and pollutant breakdown and storage of greenhouse gasses as well as human recreational opportunities including boating, paddling, fishing, hunting, birdwatching, hiking, and nature photography. Texas wetlands face intensifying challenges in the coming decades. Regulatory and legislative action should be forward-facing, anticipating effects of climate change, sea level rise, and urban expansion. Incorporating new technologies will allow for more timely and cost-efficient large-scale monitoring of wetland loss and gain. The residents of Texas are largely in support of active management of the state’s water resources; academic institutions, state and federal agencies, and conservation-minded private entities should work together to ensure the wetlands of Texas persist for wildlife and the generations to come.

“…Sorghum is cultivated for food grains in most of the arid and semi-arid regions of Asia and Africa. Whereas, in the western countries it is cultivated for green forage and feed ( Almas et al., 2015 ; Getachew et al., 2016 ; Aruna and Cheruku, 2019 ; Mundia et al., 2019 ). In most of the resource poor countries sorghum stalk is fed to animals during the lean period of the year.…”

IntroductionIn the Asian tropics, unpredictable weather increases the risk of abiotic stresses in sorghum areas, making it harder to meet predicted demand. Genotype-by environment interaction (GEI) and the lack of an effective multi-trait-based selection approach make it challenging to breed climateresilient forage sorghum that adapts to nonconventional areas.MethodsThe present investigation carried out to estimate genetic parameters, inter trait associations, genetic gain under selection (SGs) of 95 diverse forage sorghum genotypes. Fourteen forage yield and other secondary traits were evaluated at five different growing seasons at two locations. Negative and positive genetic gains under selection were estimated across different growing seasons including Kharif, Rabi and Summer in the year 2020 and 2021.Results and discussionThe GEI effects were significant (P < 0.001) for all the studied traits. The multi trait based stability indices have been said to assist breeders in ensuring sustained progress in primary traits likeforage yield without sacrificing genetic advancement in secondary traits. Fourteen genotypes were selected through each evaluation methods including genotype – ideotype distance index (MGIDI), multi-trait stability index (MTSI), multi-trait stability and mean performance (MTMPS) and multi-trait index based on factor analysis and genotype-ideotype distance (FAIBLUP Index), assuming 15% selection intensity. According to MGIDI, the selected genotypes exhibited desired positive genetic gains for dry forage yield per plant, inter-nodal length, green forage yield per plant, and plant height and negative genetic gains for days to 50% flowering. The strength and weakness plot is a potential graphical tool as portrayed by MGIDI, to identify and develop desirable genotype for particular environment. Two genotypes, G36 (302B) and G89 (348B) were found to be common across all four evaluation methods based on all the studied traits.BackgroundMulti-trait stability evaluation approaches are reliable and accessible for selecting multiple traits under varied testing environments with low multicollinearity issues. These tools proved effective in enhancing selection strategies and optimising breeding schemes for the development of climate-resilient forage sorghum genotypes. The aforementioned genotypes were found to be the most reliable, high-yielding, and earlymaturing and could be suggested for variety and hybrid development and ideotype breeding programmes to ensure the food and nutritional security.
