IGC Proceedings (1977-2023)

North Eastern states of India particularly in Manipur livestock rearing were being considered as one of the important homestead activities in the farm household. In the rural household economy, livestock is considered as an inseparable component in the whole farm business, as the production of milk and meat as well as manure, draught and transportation depends on it. It provides nutritional security to farm family and stabilizes farm income too.

As a major source of animal feeds in Manipur, fodder trees and shrubs are highly valued by farmers. They have deep root systems enabling the extraction of water and nutrients …

Framing Effect And Pastoralist Decision Making Behavior Regarding Lambing Time-An Analysis From Inner Mongolia, China, Yanting Yin, Xiangyang Hou, Xiangjun Yun, Xiliang Li

IGC Proceedings (1977-2023)

Grassland is the largest terrestrial ecosystem in China. However, it is seriously degraded. Lower stocking rates have been necessary for rehabilitating the degraded grassland. In order to rehabilitate the grassland the government proposed the “balancing animals and grass” policy. However, it has been resisted by pastoralists. (Brown et al., 2009). The reasons for the policy’s failure have been widely discussed. To date, there has been a lack of discussion on explicitly addressing the role of pastoralist behavior regarding stock numbers and lambing time. The pastoralists continue to maintain their traditional stocking rate, and take short-term adaptive measures to balance their …

Pasture Management For Sustainable Forage Production, Pijush Kanti Mukherjee, Putan Singh, S. S. Singh

IGC Proceedings (1977-2023)

In the livestock management grazing was the major feed resources in the past and even today a significant portion of livestock is being sustained on grazing resources from pastures and other grazing lands like forest, fallow lands, cultivable waste lands etc.

During the last few decades ever increasing livestock population has created enormous grazing pressure on pasture resources leading to deterioration and destruction of pastures. This has led to the urgent need of improvement of pastures as well as judicious implementation of grazing management practices. There has been certain constraints on pasture development which include fragmentation and degradation of …

Production And Quality Assessment Of Pasture Crop In Red Lateritic Wasteland Of Central Chhattisgarh, Mahendra Nath Naugraiya, G. S. Tomar

IGC Proceedings (1977-2023)

The livestock constitutes a very important component in rural economy, as in agriculture. Our country largely depends on livestock for manure and power. The availability of fodder is short from the requirement and an estimate of several agencies, there is more than 300 per cent gap between availability and requirement (Anon, 1980). Most of the livestock depend either partially or completely on natural and developed pastoral system, but the existing practices of utilization of range lands, grasslands and forest areas natural resources and increasing land degradation. In the improved pastoral system in wastelands, the carrying capacity of grass-legumes pastoral field …

Herders’ Forage-Livestock Decision Behavior In Northern Grassland Regions Of China, Xiangyang Hou, Yanting Yin, Tingting Wang

IGC Proceedings (1977-2023)

China has approximately 393 million hectares of grasslands, accounting for 41.7% of the national land area. However, 90% of useable grasslands are degraded because of human and natural reasons. Overgrazing was the dominant factor affecting grassland condition. In order to control the grassland degradation problems, the government has proposed the „forage-livestock balance‟ policy in 2002. A series of ecological policies were (Hou et al., 2013) and outcomes have been described as a “partial improvement amidst overall deterioration”. Reasons for apparent failure of the policy have been the subject of much discussion over the years. However, there has been a …

Basal Cover Of Perennial Native Grasses Increases Due To Seasonal Conditions, Meredith L. Mitchell, N. P. Linden, S. Norng, L. L. Slocombe

IGC Proceedings (1977-2023)

Australian native pastures in the high rainfall zone (> 600 mm AAR) in northern Victoria and southern NSW are usually dominated by annual species, and occupy a considerable proportion of the landscape (Pearson et al., 1997; Hill et al., 1999). Productivity of native pastures can potentially be increased by using fertiliser (Lodge 1979; Garden and Bolger, 2001) but this nearly always comes at the expense of the native perennial grasses (Garden et al., 2000; Garden and Bolger, 2001). However, using a combination of fertiliser inputs and rotational grazing can provide increased productivity while maintaining the native perennial pasture base …

The Grassland Programme (a 20-year partnership between government, conservation agencies, non-governmental organisations, and private sector) has implemented this approach to sustain and secure grassland biodiversity and ecosystem services for the benefit of current and future generations. In five years of implementation, notable achievements have been in shaping policies and …

Improving A Transhumance Livestock System Of India With Modern Technologies, Mounir Louhaichi, Arun Kumar Misra, Khem Chand, Mahesh Kumar Gaur, Douglas E. Johnson

IGC Proceedings (1977-2023)

Traditional livestock rearing systems in grasslands evolved in response to social, climatic, vegetative and technological conditions that existed scores, hundreds, or in some cases up to a thousand of years ago. Many of these systems involve vertical transhumance where flocks and herds are moved up elevation gradients for summer pasturage or horizontal transhumance in which livestock migrate across greater distances in response to regional rainfall patterns and the resulting availability of forage. In spite of the relatively low earnings of individual herders, these pastoral systems can contribute substantially to the national economies, while providing sustenance and food security to significant …

Effect Of Planting Methods And Forage Crop Combinations On Fodder Productivity Through Moisture Conservation, Kauthale Vitthal Keshav, P. S. Takawale, S. D. Patil

IGC Proceedings (1977-2023)

Out of 140.02 million ha cultivated area of the country, 76.76 million ha (54.82 %) is rainfed having soils with poor fertility and numerous physiochemical constraints. The productivity of animals is very low because of shortage of green fodder during most of the years. The poor feed quality and dry season feed shortage are the serious limitations for livestock production in rainfed areas & farmers maintain a large herd of animals to compensate for the low productivity of the livestock, which adds to the pressure on land and fodder resources (Pathak, 2005).

Western Maharashtra region suffers from very low rainfall …

Estimation Of Net Rainfall Through Guava Tree For In-Situ Soil Moisture Conservation In Guava Based Hortipasture System In Central India, Akram Ahmed, Sunil Kumar

IGC Proceedings (1977-2023)

Rainfall (R) falling on any vegetation can be partitioned in Stemflow (SF), Throughfall (TF) and Interception loss (I). Stemflow is that part of rainfall which flows down to the ground via leaves, stem, branches and trunk (above ground vegetative part). Throughfall is the part of rainfall which drips down through the canopy to the ground. Interception is the part of the rainfall after absorption by different parts of tree which remains with the above ground vegetative part and later on lost by the process of evaporation. Thus, SF and TF are combined termed as net rainfall and flow as runoff …

IGC Proceedings (1977-2023)

Spineless cactus has a high rainfall use efficiency. Under water deficit, they open their stomata during the night to capture atmospheric carbon dioxide when the air temperature is lower and relative humidity higher (Taiz and Zeiger, 2009), losing less water to the atmosphere. The rainfall use efficiency (RUE) can be expressed as the amount of water used by the crop to produce dry matter (Han and Felker, 1997). The RUE showed by spineless cactus, a CAM plant, is three to five times greater than the one observed in C₃ and C₄ plants (Felker and Russel, 1988; Nobel, 1991). …

Effects Of Alternate Furrow Irrigation On The Forage Quality Of Alfalfa (Medicago Sativa), Xiao Yu, Zhengang Guo, Tingting Jia, Yuying Shen

IGC Proceedings (1977-2023)

Alfalfa (Medicago sativa) is widely used to establish pasture to sustain animal production because of its high nutritional quality for livestock (Bouton, 2012). Therefore improving quality of alfalfa pasture is the main goal for establishing pasture throughout the world. Irrigation is an important approach for achieving high qualities of alfalfa pasture, however, the scarcity of water threatens the sustainability of world alfalfa production, requiring us to force on using water more efficiently (Liu and Guo, 2013). Alternate furrow irrigation has been proved as a water-saving technique to promote fruit quality of tomatoes and grapevines and the seed quality …

Effect Of Mulching Practices On Soil Moisture And Yield Of Forage Crops, Champak Kumar Kundu, Himangshu Das, Pintoo Bandopadhyay

IGC Proceedings (1977-2023)

One of the main impediments in the way of improvement of livestock production is insufficiency of fodder. The gap between supply and demand would further aggravate due to increase in livestock population. In eastern India and Bengal delta land is usually devoted to fodder crops beyond monsoon when soil moisture becomes a limiting factor for crop production. Appropriate soil moisture conservation practices may reduce the evaporation loss and increase the yield. Among the different soil water conservation measures, mulching has gained popularity because it reduces the direct evaporation loss of soil water by restricting the transport of water vapour from …

Waterponding The Rangelands, Ray F. Thompson

IGC Proceedings (1977-2023)

Bare, scalded semi-arid areas in western New South Wales Australia are being transformed into biodiverse native pastures, thanks to the waterponding technique which is returning clear profit to the landholder and benefits to the environment. Waterponding is a land rehabilitation technique used on duplex scalded soils in the semi-arid rangelands. Waterponding is the holding of water on the scald in surveyed horseshoe-shaped banks, each covering 0.4 ha. The ponded water leaches the soluble salts from the scalded surface. This improves the remaining soil structure, inducing surface cracking, better water penetration and entrapment of wind-blown seed. In the 1960s, it was …

Nitrogen Use Efficiency And Root Dry Matter Partitioning In Four Perennial Temperate Forage Grass Species, Luis Inostroza, Joel Ibañez, Fernando Ortega, Hernán Acuña, Pablo Undurraga

IGC Proceedings (1977-2023)

In Chile, the livestock systems based on perennial swards (grasses/white clover) have intensified its production because of the indiscriminated increases in nitrogen fertilization (Vistoso et al., 2012). Currently, new agronomic practices are demanded to allow the increase of the Nitrogen Use Efficiency (NUE) of perennial swards. In livestock systems, NUE can be studied and improved at animal, soil and plant level. In Chile, the two first levels have been broadly studied (Vistoso et al., 2012) but the plant contribution has been ignored. Today, a lot of cultivars from temperate grass species originated from different part of the world …

Tall Fescue (Festuca Arundinacea) Stockpiling Response To N Fertilizer In Southern Virginia As Affected By Biological Soil Quality, Christopher D. Teutsch, Robert Shoemaker, Alan J. Franzluebbers

IGC Proceedings (1977-2023)

Cattlemen in the eastern USA profitably utilize endophyte-infected tall fescue (Festuca arundinacea) for fall-stockpiled winter grazing. Ergot alkaloid concentration in fescue tends to decline in winter. This improves the quality of fescue for grazing when the supply of other forage becomes limited on most farms. Tall fescue dry matter yields generally respond favorably to nitrogen (N) inputs, but response can be limited with summer application due to accumulation of biologically available N in soil. Research is needed to characterize a diversity of pastures for response to N fertilizer during fall stockpiling.

Biological soil quality can be estimated with …

IGC Proceedings (1977-2023)

Overgrazing is a universal phenomenon on the Qinghai-Tibetan Plateau, which results in 90% of the alpine meadow grassland being degraded (Gao and Hou 2011). As well, animal productivity of the grassland is becoming lower because of the yearly continuous grazing. Improved grazing management will play a key role in the sustainable use of alpine meadow grasslands.

Vegetation Restoration Patterns After Rangeland Enclosure In Arid Tunisia, Khalil Mseddi, Ahmad Mohajja Al-Shammari, Hossain Sharif, Mohamed Chaieb

IGC Proceedings (1977-2023)

In Tunisia arid regions, the increase in the rural populat-ion density, (Le Floc’h et al. 1999) has intensified human pressure on natural resources through ‘‘disturbances’’ such as grazing and wood harvesting, land clearing and ploughing, which largely depend on the annual rainfall. About 10% of the steppe area has been taken over by agriculture, shrinking perennial plant cover and a highly degraded vegetation class (Hanafi and Jauffret 2008). This work assesses the vegetation restoration patterns on a protected agricultural field in Tunisian arid rangeland after 15 years of enclosure and protection against plowing.

Competition Between Lolium Perenne L. And Agrostis Capillaris L. Growing Under Different Light Regimes As Response To Fertiliser Addition In A Degraded Pasture, Paulina Flores, Ignacio F. López, Peter D. Kemp, José Dörner

IGC Proceedings (1977-2023)

At the field level plants can experience solar irradiance fluctuations caused by cloud cover or canopy shading. The majority of the research in this area has been done on forestry/pastoral systems using artificial structures so that the pasture has the desired light level (Peri et al. 2006). However, the effect of a change from high to low irradiance on the seasonal plant growth and production in a degraded pastoral system has not been previously studied, especially when fluctuating light regimes are involved. The aims of this study were to evaluate tillering dynamics of Lolium perenne L. (Lp) and Agrostis …

Monitoring Of Rehabilitation Of Degraded Rangelands, B. Bouchareb, R. Hammouda, D. Nedjraoui

IGC Proceedings (1977-2023)

The Algerian steppe covers an area of about 20 million ha, and is the barrier between the desert and the Mediterranean region. With more than 20 million sheep, overgrazing is an important issue resulting in continued degradation of the natural resources (Nedjraoui and Bedrani 2008). Trials of the rehabilitation of these ecosystems were undertaken in a participatory process with farmers complemented by some detailed monitoring of the responses in experimental plots (Hammouda 2009; Bouchareb 2012). This study reports on some results of the ecological monitoring and evaluation for a participatory project, in the steppe of South Algiers, conducted by a …
