Managing Interspecies Competition To Improve Spring Pasture, Kelly M. Mercier, Eric D. Billman, K. Soder, D. M. Jaramillo, Sarah C. Goslee, P. A. Adler
IGC Proceedings (1977-2023)
Orchardgrass (Dactylis glomerata L.) is one of the earliest maturing pasture grasses utilized in the northeastern United States. However, wet springs can delay forage harvesting resulting in advanced forage maturity and reduction in nutritive value. Chicory (Cichorium intybus L.) is a tall, upright-growing forb that shows promise as a high-energy companion crop to orchardgrass and may delay orchardgrass maturity through shading effects on plant morphology. The objective of this study was to evaluate monocultures and mixtures of orchardgrass, chicory, and white clover (Trifolium repens L.) over two consecutive springs to determine the effects of species diversity on …

Nutritive Value Of South-Central Kentucky Forbs, Tyler M. Miller, S. R. Smith
IGC Proceedings (1977-2023)
South Central Kentucky pastures serve as a host for a plethora of forbs found throughout the Upper South and Midwest United States. In this region, forbs can be numerous within pastures that are under- managed. Many producers view forbs as unwanted or weedy species and may not fully understand the value that some of these forbs provide to beef cattle. With little scientific information found on the subject for the specific geographic area, the purpose of this study was to determine what types of forbs will provide adequate nutrition for lactating beef cows. Three pastures from separate farms were used …

Irrigation Effects On Forage Dry Matter Yield And Nutritive Value Of Alfalfa, Rudra Baral, Doohong Min
IGC Proceedings (1977-2023)
Alfalfa (Medicago sativa L.) is among the top four field crops in United States (U.S.) in terms of acreage harvested and economic value. Several studies have documented that alfalfa requires high amount of water compared to other major field crops. However, more than 65% alfalfa in the U.S. is grown under rainfed condition where severe to moderate drought condition has been pronounced during alfalfa growing season. The magnitude of yield loss due to water-limited conditions is still unknown. In this context, the objective of our study is to evaluate the forage dry matter yield and forage nutritive value of …

IGC Proceedings (1977-2023)
Integrating the yield and stability of genotypes selected under grazing pressure is an important objective in breeding forage crops. Genotype × environment (G x E) interaction is a major source of inconsistency in crop performance across locations. As a result, a genotype is considered stable if it has a low contribution to the G x E interaction. This study explores the effects of G x E interaction on yield and stability of 10 tall fescue experimental populations selected for persistence under grazing pressure outside the area of adaptation of the species (stress environment). Six standard checks were included. The populations …

Opportunities For Promoting The Adoption Of Forages In Kenya, Joseph G. Mureithi, Elkana M. Nyambati
IGC Proceedings (1977-2023)
Livestock production plays an important socio-economic role in many areas across Kenya. They are kept in all the major livestock production systems including smallholder mixed crop- livestock system, crop-livestock-tree production system, and pastoral/extensive livestock production system, which occupy about 70% of land in Kenya. Livestock production is mainly constrained by inadequate feed quantity and quality. Forage forms the major source of feed for ruminant livestock as they provide high-quality forage to alleviate feed shortages. The demand for pasture and fodder production and conservation to meet livestock feed requirements, particularly during the dry seasons, has created the need to re-position the …

IGC Proceedings (1977-2023)
In Kenya, the dairy sub-sector is dominated by smallholder farmers, who keep between 1-10 dairy cows, and produce over 80% of the marketed milk in the country. The sub-sector is characterized by low milk production, long calving intervals and high calf mortality. The main constraint is the lack of year- round quality feeds hence the low lactation yield of 1,400 litres from animals capable of 3,500 - 4,000 litres. The main feed is Napier grass (Cenchrus purpureus) formerly Pennisetum purpureum. However, in the last decade the productivity and reliability of Napier grass has been constrained by the emergence Napier …

IGC Proceedings (1977-2023)
An accession of the annual legume Trigonella balansae Boiss. and Reuter. has been selected for commercial release in Australia. The annual legume has significant potential as a self-regenerating pasture within mixed farming systems. As part of a duty-of-care assessment, we tested the hypothesis that sheep grazing the trigonella cultivar will have similar liveweight, condition scores, health and wool production to sheep grazing two widely adopted annual legumes, subterranean clover (Trifolium subterraneum L. cv Dalkeith) and French serradella (Ornithopus sativus Brot. cv. Erica). Forage dry matter digestibility (DMD), crude protein (CP), fibre, mineral content and isoflavones were measured across …

IGC Proceedings (1977-2023)
As important as pasture is to productive management of cattle, sheep and goats, intensive development of grassland for ruminant animals is rare in Nigeria largely due to no conscious effort at pasture cultivation in the country. Consequently, nomadic and free grazing systems remain a practice in the country, with resultant poor animal productivity and agro-related conflicts between ruminant keepers and crop farmers and/or agro-processors. The need to revert this situation underscored the exploration of the potential value of the innovative pasture production and grazing management system tested under the Achieving Sustainable Agricultural Systems (ASSIST) programmme in Rothamsted Research, United Kingdom, …

Could Formononetin Of Red Clover (Trifolium Pratense L.) Be Enhanced By Phosphorus And Arbuscular Mycorrhizal Fungi Management?, Fernando Ortega-Klose, Andrés Quiroz, L. Bardehle, P. Aguilera
IGC Proceedings (1977-2023)
Red clover is a forage legume of importance in the world with limited persistency; in Chile this is due mainly to the root borer (Hylastinus obscurus Marsham) infestation. Our previous studies have shown that there is a strong relationship between the root borer and the formononetin content in roots of the plants; therefore, studying factors that enhance the concentration of formononetin in the plant could help to decrease the negative effect of the root borer. The purpose of this research was to assess the relationship between phosphorus availability (P) in the soil interacting with arbuscular mycorrhizal fungi (AMF) over …

IGC Proceedings (1977-2023)
In South Africa, multi-camp rotational grazing using ‘conservative stocking rates’ have been the conventional approach to livestock grazing management systems. However, as of late, the high-desnity approach (used interchangeably – depending on the situation – with regenerative grazing, mob grazing, short duration, high pressure grazing, rapid rotation, time controlled, ultra-high density, holistic grazing and holistic resource management) has been adopted by numerous farmers. This approach is considered to be an adaptable one, incorporating the ‘herd effect’ concept, whereby large numbers of animals occupy an area for short periods of time, and allowed an extended rest period. It claims to improve …

Nine-Step Approach Of Smart Agricultural Helps Grain Production Reduce Costs, Increase Yield And Efficiency, Shuqin Gao, Zhaomin Hu, Hongsheng Wang, Xiaobo Zhang, Yucheng Zhang
Bulletin of Chinese Academy of Sciences (Chinese Version)
Food security is a top priority in national governance. Since 1949, high-standard farmland construction, agricultural mechanization development, and agricultural technology promotion have all contributed to the grain production. To ensure grain security, China has drawn a “red line” of 1.8 billion mu (about 120 million hectares) as the official minimum of arable land. At the same time, increasing the investment of capital goods such as fertilizer and pesticides can no longer produce more food. Due to the extensive farming method in the past, the continuous increase in total grain output becomes difficult in the future. With the rapid development of …
