Control Of Volunteer Corn In Enlist Corn And Economics Of Herbicide Programs For Weed Control In Conventional And Multiple Herbicide-Resistant Soybean Across Nebraska, Adam M. Striegel
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
With commercialization of multiple herbicide-resistant corn and soybean cultivars, producers have new management options for controlling herbicide-resistant weeds and volunteer corn. Corn-on-corn production systems are common in irrigated fields in southcentral Nebraska which can create issues with volunteer corn management in corn fields. Enlist corn contains a new multiple herbicide-resistant trait providing resistance to 2,4-D choline, glyphosate, and the aryloxyphenoxypropionate (FOPs). Field experiments were conducted in 2018 and 2019 at South Central Agricultural Laboratory near Clay Center, Nebraska with the objective to evaluate ACCase-inhibiting herbicides and herbicide application timing on volunteer corn control, Enlist corn injury, and yield. Glyphosate/glufosinate-resistant corn …
The Significance Of Nomadic Pastoralism For Sustaining Soil Fertility In Northern Karnataka, India, Athani B., Gopikrishna, N. Kuruba
The Significance Of Nomadic Pastoralism For Sustaining Soil Fertility In Northern Karnataka, India, Athani B., Gopikrishna, N. Kuruba
IGC Proceedings (1997-2023)
Pastoralist groups in India, including the Raika of Rajasthan, Pullikulum cattle breeders in Tamil Nadu, and groups such as the Dhangar, Kuruba and Kuruma of the Deccan Plateau realize a major proportion of their income from penning their herds and flocks on farmers’ fields. Focusing on shepherds from Northern Karnataka, this paper makes a first attempt at calculating the impact of penning on livelihoods, soil fertility and the national economy.
Economics Of Camel Rearing On Grasslands In Gujarat, Khem Chand, B. L. Jangid, Subhash Kachhawa
Economics Of Camel Rearing On Grasslands In Gujarat, Khem Chand, B. L. Jangid, Subhash Kachhawa
IGC Proceedings (1997-2023)
Camel in India is primarily reared for carting/draft, agricultural operation, transportation in addition to the secondary utility of milk and hair production (Saini et al 2006). The One humped or Dromedary camel (Camelus dromedarius) is an important livestock species uniquely adapted to hot and arid environments (Schwartz, 1992). It is important livestock specie contributing significantly in rural economy and livelihood of desert dwellers in Kachchh region of Gujarat. It still plays a very distinctive role in various agricultural operations and rural transportation in dry land farming (Rajput and Tripathi, 2005). The Kachchh region of Gujarat has large camel …
Economic Review Of Pasture Development Options For North Australian Beef Enterprises, Neil D. Macleod, Dianne Mayberry, Lindsay Bell, Ian Watson
Economic Review Of Pasture Development Options For North Australian Beef Enterprises, Neil D. Macleod, Dianne Mayberry, Lindsay Bell, Ian Watson
IGC Proceedings (1997-2023)
Beef cattle grazing (~14 million head) native pastures is the dominant economic use of northern grazing lands (2.3 million km2). Few enterprises make positive economic returns in most years or achieve the necessary productivity gains (~2% per annum) to offset an ongoing cost-price squeeze (McCosker et al., 2010). A significant contributor to poor performance is low reproductive performance, management of first calving heifers, calf growth and weaning rates and liveweight gain - linked to nutrition and the low quality of pastures. Pasture development technologies (Gramshaw and Walker, 1988) are available but uptake has been poor. Three pasture development options …

Tall Fescue: Forage And Seed Production Economics, M. Anowarul Islam
IGC Proceedings (1997-2023)
Irrigated grass pastures are essential components of western U.S. agriculture, especially on cattle ranches of the intermountain region. Unfortunately, the yield and quality of these grasslands are relatively low compared to the national average because of current management practices (Jacobs et al., 1993). Attempts have been made to increase forage yields of these pastures by fertilization and applying or controlling irrigations but these efforts have resulted in minimum success (Jacobs et al., 1993). The price increase of fertilizer, energy, and fuel has made improvement of these natural grasslands more difficult and thus threatens the profitability and sustainability of …
Forage Legumes Intercropping And Nitrogen Management Effects On Performance Of Guinea Grass (Panicum Maximum) Varieties In Bundelkhand Region Of India, Mukesh Choudhary, G. Prabhu
Forage Legumes Intercropping And Nitrogen Management Effects On Performance Of Guinea Grass (Panicum Maximum) Varieties In Bundelkhand Region Of India, Mukesh Choudhary, G. Prabhu
IGC Proceedings (1997-2023)
Guinea grass (Panicum maximum Jacq.) is one of the important forage grass of the tropics with good yield potential, palatability, persistence and quality fodder (Sukhchain, 2010). The low crude protein productivity of guinea grass can be enhanced through its intercropping with forage legumes to sustain ruminant animals throughout the year. The intercropping of legumes with guinea grass will also optimize forage production per unit area, especially during rabi season. Further, its productivity can also be increased through N management as it is heavy feeder due to perennial and multi-cut nature.

IGC Proceedings (1997-2023)
The Texas High Plains are part of the largest, contiguously irrigated cropland in the USA, and draws water from the Ogallala aquifer. High crop prices, increased demand for maize for ethanol production, and severe drought have increased water depletion rates. Research has shown that integrating forages and grazing cattle into the cotton-dominant cropping system can reduce overall water use (Allen et al. 2012) while still offering farmers positive net returns (Johnson et al. 2013). Integrating forages with row crops also reduces needs for nitrogen (N) fertilizer, rebuilds soil organic matter (Acosta-Martinez et al. 2010), and reduces fossil energy …
The Value Of Modeling Botanical Composition Change In Grasslands, Karl Behrendt
The Value Of Modeling Botanical Composition Change In Grasslands, Karl Behrendt
IGC Proceedings (1997-2023)
The integration of grassland dynamics, livestock production and economics is necessary to improve decision making regarding grassland resource development and management. Within a sward, the relative competitive ability of different species and the way management interacts with the environment both play a significant role in determining the competition between species, future states of the grassland sward, ecological impact of the grassland and its potential for livestock production (Kemp and King, 2001). The impact of botanical composition shifts on grassland productivity will depend on the nutritive value and yield potential of the invasive species against those of the resident species. The …
Integrating Beef And Cotton Production Reduces Irrigation Needs In The Texas Southern High Plains, C. Philip Brown, V. G. Allen, Rick Kellison, P. Green, C. J. Zilverberg, P. Johnson, V. Acosta-Martinez, C. P. West
Integrating Beef And Cotton Production Reduces Irrigation Needs In The Texas Southern High Plains, C. Philip Brown, V. G. Allen, Rick Kellison, P. Green, C. J. Zilverberg, P. Johnson, V. Acosta-Martinez, C. P. West
IGC Proceedings (1997-2023)
The Texas High Plains is a semiarid agricultural region located in the central south plains of the United States. This area exemplifies semiarid regions where water is becoming scarce. Crop production depends heavily on irrigation primarily from the Ogallala aquifer at non-sustainable rates of use. Irrigated monoculture cotton (Gossypium hirsutum L.) is the dominant crop but grazing livestock in this once vast grassland is re-emerging as the aquifer declines. Environmental benefits of integrated crop and livestock systems have been suggested. We compared a cotton monoculture with an integrated cotton-forage-beef stocker steer system over 10 yr to determine effects on …

A Strategic Approach To Developing The Role Of Perennial Forages For Crop-Livestock Farmers, Rick Llewellyn, Michael Robertson, Richard C. Hayes, David Ferris, Clinton K. Revell, Katrien Descheemaeker
IGC Proceedings (1997-2023)
A substantial proportion of Australian animal production from grazing comes from regions and farms where cropping is the major enterprise. Developing new and improved grazing systems for mixed farms where crop production is the major driver of farm management decisions presents a unique research and development challenge. In this paper we describe a multi-disciplinary farming-systems research approach (‘EverCrop’) aimed at improving farm profitability, risk management and environmental impacts through the development and integration of new grazing options. It has been used to analyse and target new opportunities for farmers to benefit from perennial species across dry Mediterranean-type and temperate regions …
