Potato Cyst Nematodes: A New Threat To Potato Production In East Africa, Harrison Mburu, Laura Cortada, Solveig Haukeland, Wilson Ronno, Moses Nyongesa, Zachary Kinyua, Joel L. Bargul, Danny Coyne

All Peer-Reviewed Publications

Potato cyst nematodes (PCN), such as Globodera rostochiensis and Globodera pallida, are quarantine restricted pests of potato causing major yield and financial losses to farmers. G. rostochiensis was first reported from Kenya’s key potato growing area in 2015. We sought to determine the diversity, prevalence and distribution of PCN species across the country by conducting a country-wide survey between 2016 and 2018, which included a more focused, follow-up assessment in three key potato growing counties. A total of 1,348 soil samples were collected from 20 potato growing counties. Information regarding local potato farming practices, potato cultivar use, their diversity and …

Biomass And Carbon Stock Estimation In Woody Grass (Dendrocalamus Strictus L.) In Doon Valley, India, V. Subbulakshmi, Rajesh Kaushal, J. M. S. Tomar, N. M. Alam, J. Jayparkash, Harsh Mehta, A. K. Gupta, A. C. Rathore, O. P. Chaturvedi, P. K. Mishra

IGC Proceedings (1977-2023)

Bamboos commonly kown as woody grass are one of the most important species particularly in Asia, where it is frequently considered as the ―timber of the poor‖ (Rao et al., 1985). With about 23 genera and 136 species, India is the second largest reservoir of bamboos, next only to China (SFR, 2013 and Nath et al., 2009). Bamboos occur extensively in the managed ecosystems of India—both as plantations (and in agroforestry (scattered clumps, hedgerows on farm boundaries etc.

Dendrocalamus strictus L. is most commonly found bamboo in India. It is widely distributed in dry deciduous forests and grows rapidly …

Effect Of Including Arachis Pintoi In Tropical Forages Diets Megathyrsus Maximus And Brachiaria Humidicola On In Vitro Methane Production, Diana Marcela Valencia Echavarría, Luis Alfonso Giraldo Valderrama, Alexandra Torres, Alejandra Marín Gomez

IGC Proceedings (1977-2023)

Ruminants have the capability to ferment structural carbohydrates found in forages and obtain from them a usable form of energy to produce high quality food, i.e milk and meat (Kamra et al., 2012). However, as a gaseous by-product from the enteric fermentation of those carbohydrates, methane is produced in a significant proportion, being considered as one of the most important greenhouse gases (GHG). In Colombian tropical livestock, inclusion of legumes in on poor quality grasses diets based have allowed an improvement of their nutritive quality, besides enteric methanogenesis reduction because their content of condensed tannins (CT); however, this is not …

Phyto-Ruminal-Bioremediation: Grasses To The Rescue, Morrie Craig, Jennifer Duringer, Linda Blythe

IGC Proceedings (1977-2023)

The US EPA has defined Super Fund sites for 594 toxins in the United States. The EPA definition of toxins is one that causes acute or chronic human health effects, or causing significant environmental harm. One of the categories of toxins is nitroaromatic molecules, which are used primarily as munitions. In the United States alone there are 16,000 Department of Defense (DoD) sites. The most common munitions there are TNT, RDX, HMX, and 2,4 DNT. In the world, these sites range historically from World War II residues to those from recent Middle East conflicts. Human health effects from these toxins …

Comparison Of Two Different Pasture Species Compositions For Recovery Of Deep Soil Nitrogen During Winter, Brendon Malclom, Keith Cameron, Grant Edwards, Jim Moir, Hong Di

IGC Proceedings (1977-2023)

Surplus nitrate (NO₃^-) beneath animal urine patches is highly vulnerable to leaching, particularly during winter when soil drainage is often highest. Most common pastures in New Zealand (i.e. Lolium perenne) have relatively shallow root systems and produce low dry matter (DM) yields during winter months. Recent investigations suggest that alternative pasture species may be able to recover more soil nitrogen (N) during winter and consequently reduce NO₃^- leaching losses (Moir et al., 2013; Malcolm et al., 2014; 2015). However, further work is required to better understand the importance of root system architecture and plant …

Effect Of Selected Tanniniferous Leaves On In Vivo Enteric Methane Emission In Sheep, M. Saravanan, R. Bhatta, L. Baruah, P. K. Malik, N. Ravi

IGC Proceedings (1977-2023)

Concentration of methane is continuously increasing in atmosphere and now almost 155% (IPCC, 2007) more than that recorded during pre-industrial era. Livestock production is a major sector accountable for high methane emission into atmospheric pool. World’s livestock is contributing around 15% of total atmospheric methane on annual basis feeds (Moss et al., 2000). Additionally, methane emission from ruminants leads to a loss of 2 to 15% of the dietary energy (Holter and Young, 1992). Due to these two crucial issues, researchers are working tirelessly to find a suitable and effective way for enteric methane amelioration accompanied with minimal inputs. …

Methane Emission Estimated From Different Cattle Intake Data In Heifers Grazing A Tropical Pasture, José Augusto Imaz, O. Hernández, D. Dos Santos, A. Radrizzani, J. I. Arroquy

IGC Proceedings (1977-2023)

The quantification of methane (CH₄) from enteric fermentation related to cattle diet is a useful tool to identify strategies to mitigate greenhouse gas emissions. This is even important in tropical and subtropical regions due to the lack of CH₄ estimations in beef cattle, particularly from Bos Indicus breeds grazing tropical grasses (Kurihara et al., 1999). Several modelling approaches have been developed in order to predict CH₄ emission. However, the use of these models has limitations associated with uncertainty information required such as feed intake (FI), composition of the selected diet and animal responses (Gonzalez et …
