Role Of Panicum Turgidum Dominated Rangelands In Conservation Of Caralluma Edulis In Thar Desert, India, Kulloli Ravikiran Ningappa, Suresh Kumar, J. P. Singha

IGC Proceedings (1977-2023)

Rangelands are colonized vast natural landscapes in the form of grasslands. These are mostly dominated by native grass species. Once a patch is colonized by a pioneer species, complex interactions may develop among plants of different species. The frequency of positive interactions has been shown to be high in harsh environments, particular in arid environments, where it has been identified as a driving mechanism of vegetation dynamics (Bruno et al., 2003). These processes commonly involve nurse plants (Niering et al., 1963) that facilitate the establishment of other plants species beneath their canopies (Franco and Nobel, 1988). Based on …

Genetic Resources For The Improvement Of Switchgrass (Panicum Virgatum L.) For Biomass And Forage, Gautam Sarath, Nathan A. Palmer, Aaron J. Saathoff, Robert B. Mitchell, Serge Edme, Erin D. Scully, Scott E. Sattler

IGC Proceedings (1977-2023)

Switchgrass (Panicum virgatum L.) is an important forage and biomass species for many parts of the USA. Switchgrass can be of several ploidies. Octoploid cultivars are most often used in forage and conservation settings, while the tetraploid cultivars are mostly targeted for bioenergy end-uses, due to their higher biomass yields. Switchgrass populations also occur as upland and lowland ecotypes, and constitute different heterotic groups. Switchgrass is mostly an obligate outcrosser resulting in substantial genotypic and phenotypic variation within populations. In the last ~15 years, significant resources have been dedicated to both breeding and understanding the genomic makeup of this …

Florpyrauxifen-Benzyl Use In Arkansas Rice (Oryza Sativa L.), Hannah Elizabeth Wright

Graduate Theses and Dissertations

Florpyrauxifen-benzyl is a synthetic auxin herbicide which was commercially released in 2018 to combat troublesome grass, broadleaf, and sedge weed species in rice. Many factors may influence cultivar response to a new herbicide; hence, it is important to understand factors contributing to crop sensitivity to an herbicide in order to make appropriate recommendations. Prior to the onset of this study, research had been conducted on florpyrauxifen-benzyl in a flooded environment; however, none had been executed in a non-flooded environment. Experiments were conducted to evaluate the response of a long-grain variety ‘CL111’, a medium-grain variety ‘CL272’, and a long-grain hybrid ‘CLXL745’ …

The Landscape As A Unit For Rangeland Inventory In Arid And Semi-Arid Regions Of Iran (Case Studies: Touran Biosphere Reserve And Behkadaye Rajinia Development Project), Mansour Mesdaghi

IGC Proceedings (1977-2023)

Severe land fragmentation, degradation, and pollution problems will force us to think about a rural community and research group in Iran to combine our experiences and skills to deal with the challenges of improving land use sustainability (Bosch at el.1995; Mesdaghi, 1993). Planning rangeland inventory requiring recognition of the ecological processes operating at different scales and their particular characteristics (Friedel and Laycock, 1995).

In ancient countries like Persia (Iran), past land use suggests that rangelands exploitation by local herders was co-adapted with natural environments (Nyerges, 1980; Mesdaghi, 1993). Iranian rangelands, however, were nationalized through the land reforming and the …

Livestock Grazing In India: Policy Issues, M. M. Roy

IGC Proceedings (1977-2023)

The grazing/range lands have been very important in India since ancient times when cattle breeding and milk production was regarded as the second most important profession, next only to agriculture. However, during last five decades increasing domestic animal population has placed enormous grazing pressure on such lands, leading to grassland deterioration and desertification especially in arid and semiarid regions (GOI, 2007; Kala, 2009).

Still, grazing based livestock play an important role in rural economy of the as well over 50 per cent of them depend on grazing (of varying degrees) in forests, community lands and other lands in many parts …

Community Pasture Development As An Approach To Common Property Resources Management In Rajasthan, India, Jayprakash Sharma

IGC Proceedings (1977-2023)

Semiarid areas of the state of Rajasthan have community lands in almost every village. Most of them are grouped under wastelands and are usually covered with coarse grasses such as Dichanthium, Cenchrus and Lasiurus. Grass growth on these lands faces constraints such as extreme temperatures, steep slope, variable precipitation and scarcity of water in general. Land degradation has created tremendous pressure on increasing livestock, especially the goat population. As pasture management and enhancement of productivity of improved grasses were key factors to sustain livestock through common property resource management, BAIF Development Research Foundation, a rural development organization, implemented projects …

Conservation Prioritization Of Semi-Arid Savannas In India: A Multi-Scale Landscape Approach, Abi Tamim Vanak

IGC Proceedings (1977-2023)

The semi-arid savanna grasslands of peninsular India are unique habitats that support a vast proportion of Indiaís agropastoralist community. They are also home to critically endangered species such as the Great Indian bustard and other endangered and endemic species such as the Indian wolf (Canis lupus pallipes) and blackbuck antelope (Antilope cervicapra). Unfortunately, savanna grasslands have not received the attention of conservationists or policy makers, resulting in a lack of protection for both the endangered and endemic wildlife as well as the habitat. Given the high human-dependence on these biomes, traditional conservation measures such as large protected areas are not …

Enhancing The Productivity Of Grassland And Wasteland Through Management In Hills, Jaideep Kumar Bisht

IGC Proceedings (1977-2023)

Total area available for grazing in the country is about 40% of the land area. Pasture lands constitute the main grazing resources of the country, available over an area of 12 million ha (3.94% of the geographical area). An idea of the meager fodder availability can be had from the fact that about 50% of the cattle population, depending largely upon free rangeland grazing in forests, pastures, village commons and the like, end up getting only about 1.5 kg of dry fodder/ day/ ACU (Adult Cattle Unit) as against the healthy fodder requirement norm of 3% body weight. The grasslands …
