IGC Proceedings (1977-2023)

Sweet sorghum owing to its high fodder yielding ability coupled with sweet and juicy stalks is more often used as a fodder crop in India than for its intended use as a sugar or bio-energy crop (Nimbkar et al., 2010). In addition, fodder quality of sweet sorghum is as good as that of the fodder sorghums. Sweet sorghum is also produced as forage in China (Zhu, 1998) and USA (Suttie, 2000). Sorghum genotypes rich in sugar are reported to have a better quality of fodder than the regular genotypes with low sugar content (Singh and Katiyar, 2003). With its …

Test Using Sedimentary Records To Quantify Extreme Paleo-Flood: A Case Study Of An Oxbow Lake In South Carolina, Molly Aeschliman

Honors Theses

Extreme flooding has become an increasing issue along the coasts for people’s health and infrastructure stability. As the effect of climate change continues to persist, the need to prepare for such events becomes imperative. To improve the understanding of climatic forecasting with regards to extreme flooding, there is merit in searching flooding history beyond the instrumental records. There has been some work done in the past to correlate extreme flooding and its sedimentary traces preserved in floodplain depressions, such as oxbow lakes, based on the assumption that the coarser grain sediments in the sediment layers correspond with higher peak discharges …

Using Foraminifera To Identify Overwash Deposits In St Vincent Island, Florida In The Wake Of Hurricane Michael, Kayla Washington

Honors Theses

Major hurricanes have geomorphic and stratigraphic impacts in coast environments that can be used to identify and characterize the storms. One of the approaches to identify storm impact is by studying assemblage of foraminifera, small organisms that live primarily in marine environments with some species living in marshes, in coastal marshes or ponds, with the assumption that storm-induced overwash flooding brings marine species ashore. Hurricane Michael made landfall ~40 km northwest of St Vincent Island (SVI), Florida, on October 10, 2018, as a Category 5 storm. The storm surge of Michael inundated a large part of SVI, which offers a …

Stability Analysis In Dual Purpose Maize Line, R. P. Sah, Shahid Ahmed, D. R. Malaviya, Pradeep Saxena

IGC Proceedings (1977-2023)

Utilization of maize as dual purpose has increased the economic value of the crop. Dual purpose maize not only meets the demand of grain but also the stover for cattle. The genetic improvement in dual purpose maize should combine breeding for grain with specific needs of forage [Barrière et al., 2005]. Stability in dual purpose maize production is an essential component for sustainable production. The selection of dual type maize should be based on the genotype × environment interaction (GEI) and stability/ adaptability. Parametric models, such as Eberhart and Russell (1966) based on simple linear regression analysis are among …

Persistence Of Red Clover (Trifolium Pratense L.) Is Highly Related To Plant Population: Preliminary Studies On Isoflavones That Could Act As Insect Deterrents, Fernando Ortega, Andrés Quiroz, Leonardo Parra, Ana Mutis, Emilio Hormazabal, Muriel Melo

IGC Proceedings (1977-2023)

Red clover (Trifolium pratense L.) is a valuable legume in Chile whose importance is mainly as forage for animal and seed production. Although it is considered as perennial, its production declines after the second year of established due to a complex of multiple biotic and abiotic factors (Taylor and Quesenberry, 1996, Ortega et al., 2014); in Chile this is due mainly to the infestation by the red clover root borer Hylastinus obscurus (Coleoptera: Curculionidae). Currently there is no an efficient control method against this insect. Therefore, breeding cultivars that are less attractive to the root borer and the …

Mineral-Surface Chemistry Of Hydroxyapatite And Urea-Rich Solutions, Estefania Garcia

Master of Science in Chemical Sciences Theses

On this planet the development of life requires six essential elements: C, H, O, N, P, and S. These elements are present in gaseous form, with the exception of phosphorus, which is primarily found in solid mineral sources. Phosphorus in biological systems is significant through its involvement in metabolic functions (e.g., Coenzyme A), cell structure (i.e., phospholipid membranes), and genetic storage/transfer (i.e., phosphodiester bonds in DNA and RNA). However, an ambiguity remains with the assimilation of phosphorus in biological systems, caused by its habitual presence in insoluble phosphate mineral sources. Recent research has found that insoluble phosphate …

IGC Proceedings (1977-2023)

Globally, abiotic stress is the primary cause of crop loss, reducing the average yields of most major crop plants by more than 50% (Bray et. al., 2000). Drought stress is one of the most widespread environmental stresses when the total area of arable land is classified according to the occurrence of various stress factors (Arora et al., 2002).

Drought and other abiotic stresses limit the photosynthetic activity of various crops, which in turn reduces the production of photosynthetic assimilates. Almost every developmental stage of the plant is affected by water stress. However, it has been observed that drought …
