This book was released on 2019 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most of the recent studies focus on the consequences of extreme weather on crop yields, especially on droughts and hot weather. However, knowledge of the consequences of excess precipitation on crop yield and subsequent consequences on the food production system is lacking. Therefore, we attempted to fill that knowledge gap. In this study, we collected historical crop yield data for Texas by county for grain sorghum and the historical daily precipitation data from weather stations within the county. The precipitation data (from the nearest station(s) to the cultivated area) and crop yield data were shortlisted (based on length of record and absence of missing values) and arranged for the period 1973-2003 covering a variety of crop growing seasons. Grain sorghum crop growing periods in different parts of Texas was estimated based on the east-west precipitation gradient, north-south temperature gradient, and typical planting and harvest dates in Texas. Using the daily time series of precipitation data, we estimated the growing season total precipitation and maximum 4-day total precipitation for each county growing rainfed grain sorghum. Using the two parameters mentioned above as independent variables, and crop yield of sorghum as the dependent variable, we tried to find out relationships between excess precipitation and decreases in crop yields using both graphical and mathematical relationships. Results were analyzed in four different levels 1. Storm by storm consequences on crop yield; 2. Growing season total precipitation and crop yield; 3. Maximum 4-day precipitation and crop yield; and 4. Multiple linear regression of independent variables (Growing season total precipitation and maximum 4-day precipitation and crop yield) and dependent variable (yield of rainfed grain sorghum) with and without a principal component analysis (to remove the relationship between confounding independent variables). Our graphical and mathematical results point out excess precipitation can decrease rainfed sorghum yields in Texas. Our results also suggest the rainfed sorghum yield reductions by excess precipitation can range from 18 to 38%.

Download or read book Effect of Soil Salinity Fertilization Water Table Depth and Runoff Control on Production of Nonirrigated Grain Sorghum in the Lower Rio Grande Valley written by Leon Lyles and published by . This book was released on 1965 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: The results of a 3-year study show no statistically significant differences in grain yields among six fertilizer treatment of nonirrigated grain sorghum. Apparently nutrient reserves are adequate for maximum production under existing soil salinity and rainfall conditions. Grain sorghum yields were related to the underground water table depth at seeding to fallow season rainfall and to the soluble salt concentration in the 0- to 3-foot soil depth. Water table depths of 3.35, 5,20 and 7.65 feet at seeding in 1961, 1962 and 1963, respectively, were associated with average grain yields of 3,627, 2,672 and 1,556 pounds per acre. It was determined that a 1-mmbo-per-centimeter increase in soil salinity at the 2- to 3-foot depth resulted in an average decrease of 180 pounds of grain per acre within the -5- to 11-mmhos-per-centimeter range of salt levels exhibited by the test site. Runoff control did not significantly affect yields any year. Absence of timely runoff, high evaptranspiration between crop season, and a high water table that equalizes soil moisture storage apparently explains tha lack of yield response to runoff control.

Download or read book Global Agricultural Production Resilience to Climate Change written by Mukhtar Ahmed and published by Springer Nature. This book was released on 2023-01-01 with total page 628 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers all aspects related to climate change and agriculture. The book discusses Global Climate Models (GCMs), Coupled Model Intercomparison Project (CMIP) and application of strategic management tool that includes RCP (Representative concentration Pathway), SSP (Shared Socio-economic Pathways) and SPA (Shared climate Policy Assumptions). The book provides information on how climate change, agricultural productivity and food security are interlinked. The impacts of climate change on food security are studied through different climatic drivers e.g., ENSO (El Niño–Southern Oscillation) and SOI (Southern Oscillation Index). These drivers are responsible for the climatic extreme events hence early prediction of these drivers could help to design appropriate adaptive measures for the agriculture sector and could be considered as early warning tools for risk management. Similarly, climate change and process-based soil modeling as well as the role of soil microbes and climate smart agriculture are discussed in this book. Climate change impacts on legume crop production and adaptation strategies are presented, with details about cereal crop modeling, perspectives of Camelina sativa as well as low input biofuel and oilseed crop, greenhouse gases (GHGs) emissions and mitigation strategies.

Available in PDF, EPUB and Kindle. Book excerpt: Emissions of carbon dioxide from the burning of fossil fuels have ushered in a new epoch where human activities will largely determine the evolution of Earth's climate. Because carbon dioxide in the atmosphere is long lived, it can effectively lock the Earth and future generations into a range of impacts, some of which could become very severe. Emissions reductions decisions made today matter in determining impacts experienced not just over the next few decades, but in the coming centuries and millennia. According to Climate Stabilization Targets: Emissions, Concentrations, and Impacts Over Decades to Millennia, important policy decisions can be informed by recent advances in climate science that quantify the relationships between increases in carbon dioxide and global warming, related climate changes, and resulting impacts, such as changes in streamflow, wildfires, crop productivity, extreme hot summers, and sea level rise. One way to inform these choices is to consider the projected climate changes and impacts that would occur if greenhouse gases in the atmosphere were stabilized at a particular concentration level. The book quantifies the outcomes of different stabilization targets for greenhouse gas concentrations using analyses and information drawn from the scientific literature. Although it does not recommend or justify any particular stabilization target, it does provide important scientific insights about the relationships among emissions, greenhouse gas concentrations, temperatures, and impacts. Climate Stabilization Targets emphasizes the importance of 21st century choices regarding long-term climate stabilization. It is a useful resource for scientists, educators and policy makers, among others.
