In Ladakh, livestock rearing is a major activity in the livelihoods of the population and contributes greatly to income generation in the region and therefore alleviating poverty. In agro-pastoral animal husbandry systems of Leh, Khaltsey, and Nubra blocks and limited areas in Nyoma and Durbok, villagers live in settled communities and practice sedentary agriculture, but they also keep relatively large herds of livestock to augment income and meet dietary and fibre subsistence needs (Ahmed, 2002). Due to prolonged and extreme cold winter, the agriculture season is very short which starts from May and ends by September depending upon different altitudes. …

Livestock acquires special importance in mountain farming system from both ecological and socioeconomic point of view. They are an integral part of the farming system and a “bridge’’ connecting two types of land viz., forest and cultivated. In hilly regions, the arable agriculture is not very remunerative; therefore farmers of all categories rear sheep, goats, cattle etc. under sedentary, semi-migratory and migratory systems to supplement family income (Dev et al., 2014). The common property resources (CPR) and degraded pasturelands are the major feed sources. Remotely sensed satellite imagery and Geographic Information System (GIS) are being widely used for the …

IGC Proceedings (1977-2023)
Silvipastures are one of the important resource bases of a country. They are not only the main source of herbage availability for the livestock rearing and wildlife but also the major instrument for wasteland rehabilitation. Despite of enormous importance, there was a huge gap about the available information on natural forage resources (grasslands/forage trees/silvipastures), their makeup, successions, and coverage constrains and scope for improvement (Dabadghao and Shankarnarayan, 1973). Therefore, an attempt has been made to identify and delineate the natural silvipastoral cover of India which will help in effective planning and execution of watershed development and other forage programmes wherein …

Long-Term Effects Of Tillage And Residue Management On The Soil Microbial Community Structure In The Loess Plateau, Qian Yang, Xianzhi Wang, Yuying Shen
IGC Proceedings (1977-2023)
The severe soil erosion present in the Loess Plateau of western China has resulted from a combination of highly erodible soil, variable rainfall and intensive cultivation (Shi and Shao 2000). Conservation agriculture practices, including no till, crop residue retention and crop rotation, have been found to increase crop yield, improve water use efficiency, reduce energy inputs and improve soil fertility (Bukert et al. 2000; Rahman et al. 2008). The soil microbial community function and structure play key roles in the decomposition of organic matter, nutrient cycling and altering the availability of nutrients to plants, which has been shown …

Does Litter Decomposition Rate Indicate Species Status In The Plant Community Of Alpine Meadow?, Yongchao Zhang, Decao Niu, Tong Han, Dianye Zhang, Hua Fu
IGC Proceedings (1977-2023)
Litter decomposition is the physical and chemical breakdown of dead plant material, which is affected by the litter quality, environmental conditions and the composition of decomposer communities (Parton et al. 2007). Within biomes, environmental conditions set a similar background broadly (Berg et al. 1993; Moore et al., 2001; Raich et al. 2006; Parton et al. 2007) and microbial communities are assumed to be ‘functionally equivalent’ in terms of carbon metabolism (Andrén and Balandreau 1999). Consequently, litter quality has been considered as the predominant control on the rate of decomposition of organic matter in the ecosystem (Cornwell …

Effect Of Slope Aspect On Arbuscular Mycorrhizal Colonization Of Centipedegrass In A Hill Pasture, Manabu Tobisa, Yoshinori Uchida, Yoshinori Ikeda
IGC Proceedings (1977-2023)
Arbuscular mycorrhizal fungi (AMF) form a symbiotic association with more than 80% of terrestrial plants and benefit their hosts principally by increasing uptake of nutrients. This is particularly important for phosphorus uptakes as fungal extraradical mycelium can access relatively immobile phosphate ions through an ability to grow beyond the phosphate depletion zone that rapidly develops around the root (Gosling et al. 2006). This symbiotic association is known to promote growth and improve drought and disease resistance of the host plants (Gosling et al. 2006). Centipedegrass (Eremochloa ophiuroides (Munro) Hack.) is a warm-season perennial that is native to central …

IGC Proceedings (1977-2023)
Soil microbial biomass (MBC), as the most active of soil organic constituents, controls many important ecological processes in the ecosystem including nutrient cycling and litter decomposition (Jia et al. 2010), and is considered to be the most sensitive biological indicator of soil quality (Sinha et al. 2009). Moreover, soil microbial metabolic quotient (qCO2) reflects the quantity and quality of soil organic matter, soil nutrient availability, microbial substrate utilization efficiency and ecosystem stability (Mao et al. 2010). Shrub is the dominant vegetation of desert ecosystems, contributing to soil nutrient conservation and carbon sequestration. Considerable research related to shrubs in desert …

IGC Proceedings (1977-2023)
Elephant grass (Pennisetum purpureum Schum.) is one of the most productive warm-season grasses. Farmers utilize elephant grass in different forms, such as cut-and-carry operations, grazing, conserved forage (silage, hay), and as an energy source (Lira et al. 2010). Nitrogen (N) is an essential element for plant growth and development and it is usually a limiting factor for forage production in the tropics (Boddey et al. 2004). Biological N fixation (BNF) may occur in warm-season grasses by their association with diazotrophic bacteria. These bacteria colonize different niches in the host plant. Endophytic bacteria form colonies inside the plant tissue …

IGC Proceedings (1977-2023)
Nitrogen (N) is one of nature´s most abundant elements, accounting for about 78% of the atmospheric gases, but mostly as the inert N2 form. As such it is not directly available to plants, and is relatively scarce in most agroecosystems. Biological nitrogen fixation (BNF) through diazotrophic bacteria represents ca. 63% of the yearly N input in terrestrial ecosystems (Taiz and Zeiger 2004). Legumes which form effective symbiosis with the diazotrophic group of bacteria commonly known as rhizobia, are a very important source of available N. Tropical forage legumes are usually able to nodulate with a diverse population of rhizobia, …
