IGC Proceedings (1977-2023)

Brachiaria ruziziensis is an important fodder crop suitable for high rainfall areas and soils with low nutrient supply. Though the area under B. ruziziensis cultivation in India is not properly documented, it is widely grown in Kerala (Stür et al. 1996) and in parts of Karnataka and Goa. By virtue of its shade tolerance and adaptability, B. ruziziensis have wide scope for adoption in other parts of India. In India, Brachiaria is mainly planted through root slips as availability of good quality filled seeds is very less. It is known that the proportion of filled to unfilled seeds depends …

Multiple Scale Impacts Of Nomad Settlement On Social-Ecological Systems, Mingming Fan, Wenjun Li

IGC Proceedings (1977-2023)

There are complex interactions and feedback mechanisms between human and natural systems within the coupled social-ecological systems (SESs) (Liu et al. 2007, Li and Li 2012). Human society is the major driving force that changes ecosystem dynamics from local environments to the biosphere (Liu et al. 2007, Kirch 2005). Grasslands, especially the vulnerable arid and semi-arid grassland ecosystems upon which pastoralists live and graze livestock, can be considered as SESs; pastoral activities influence the biophysical environment and set up interactions between the components of these systems (Robinson 2009). In recent years, the ecosystem services provided by grasslands and …

Improving Smallholder Livelihoods: Dairy Production In Tanzania, Edward Ulicky, Jackson Magoma, Helen Usiri, Amanda Edward

IGC Proceedings (1977-2023)

Tanzania is primarily an agro-based economy, characterized by subsistence agricultural production that employs more than 80% of the population and contributing up to 45% of the GDP (2005). This country is endowed with a cattle population of 21.3 million, composed mainly of indigenous Zebu breed and about 680,000 improved dairy animals. About 70% of the milk produced comes from the traditional sector (indigenous cattle) kept in rural areas, while the remaining 30% comes from improved cattle mainly kept by smallholder producers. In Northern Tanzania and particularly in Hai district of Kilimanjaro region, some dairy farmers organize themselves into small producer …

Population Of Fungi Associated With Seed Germination After Storage And Seed Treatment, Alaba O. Jolaosho, Adijat Olabisi Atayese, Olufunmilayo Comfort Amed, Bolanle Temitope Akinyemi, Jimoh A. Olanite, Victoria O. A. Ojo

IGC Proceedings (1977-2023)

Fungi growth occurs in seeds as a result of environmental conditions (high relative humidity, suitable temperature and high level of seed moisture content). But pathogen free healthy seeds are required for plant propagation. Microbial and insect attack affect seeds throughout the life cycle of the plant (Islam et al., 2009). Fungi are the most common microbes that affect seed germination and they can be both saprophytic and pathogenic. Hence, the aim of this experiment is to determine the cultural and morphological characteristics and population of fungi associated with the germination of some legume seeds after storage and scarification.

Productivity Of Grasses In Association With Hardwickia Binata Under Rainfed Conditions, S. N. Ram, Ajoy K. Roy, A. K. Shukla

IGC Proceedings (1977-2023)

Adoption of silvipasture system on wastelands offers, without impairing the growth of trees, an extra yield of grass during monsoon season and top feed during summer seasons. The leaf fodder from the hardy trees and shrubs serve as an insurance against fodder scarcity during drought to the livestock. In view of this the present study was carried out to assess the productivity of different grasses in association with Hardwickia binata under moisture conservation practices under rainfed condition.

Quality Fodder From Fruit Trees For Sustainable Forage Production In Semi-Arid Tropics, Sudhir Kumar

IGC Proceedings (1977-2023)

India being at the crux of exploding livestock population in the world, needs to reorient agroforestry potential by inducing the fruit trees based hortipastoral systems to minimize the existing gap between fodder supply and demand from arable farming system. It is realized that in some part of the country probably more animals are depending on shrubs and trees than on grass and legume based pastures. At this juncture of main farm resource limitations, the community can exploit fruit trees to a considerable extent for fodder along with the supplementary benefit from fresh and/or processed fruits. Interestingly, the leaves which usually …

IGC Proceedings (1977-2023)

Goats and sheep play a significant role in the subsistence economy in India. Goats and sheep are multipurpose animals which provide hair, wool, meat, milk and skin. The production of meat from goats and sheep play a vital role in the supply of animal protein for the people of our country. Small ruminant production in village systems in tropical countries is often characterized by poor growth rates and high mortality (Devendra and Burns, 1970). The productivity of small ruminants can be improved by improving the nutrition either through concentrate feeding or provision of additional forage (Pathasarathy et al., 1984). …

Studies On Silvi-Pasture Systems For Intensive Fodder Production, R. Susheela, R. V. T. Balazzii Naaiik, M. Shanti, T. Shashikala, M. Anuradha, V. Chandrika

IGC Proceedings (1977-2023)

Silvi-pastoral system with suitable species of trees and grasses help in increasing the land productivity and also maintain environmental potentialities. Moreover, deep root system of trees bind the soil, reduces erosion and extracts moisture from deeper strata of the soil. The effects of tree species on associated crops in agro forestry system are not consistent. The association of cereal and legume forages not only maintains similar level of herbage yield but also nearly doubles the crude protein production. Study of the right combination of tree species and associated crop in agro forestry for this region is the need of the …

Forage From Trees And Grasses Of Silvipasture System In Degraded Land Of Semiarid India, R. V. Kumar, Harsh Vardhan Singh, Sunil Kumar, Ajoy K. Roy, P. K. Ghosh

IGC Proceedings (1977-2023)

Rainfed agro-ecosystem has a distinct place in Indian Agriculture, occupying 67% of the cultivated area and supporting 65% of the livestock population (Venkateswarlu, 2005). The silvipasture systems involving suitable multi-purpose trees specially fodder trees and range grass species provide resilience by ensuring continued and multiple outputs such as, forage, fuelwood, fodder, fibre and industrial raw material, besides other positive environmental effects. Incorporation of fodder trees with grasses is perceived as a climate change-resilient cropping system for farmers linking climate change mitigation with adaptation (Mbow et al., 2014). The synergies of tree-grass association need to be explored and exploited by …

Grassland Management In Wildlife Protected Areas (Pa's) In India, R. K. Pandey

IGC Proceedings (1977-2023)

Ecological status of Indian grasslands had been a subject of conflicting opinion in the past. Existing grasslands are anthropogenic in origin except, Himalayan meadows in high altitudes. Extensive clearing of the forests for human settlements, agricultural cultivation and domestication of animals in the past have been resulted into opening of pockets/grasslands amidst the forest areas. Such tame grasslands are categorized as succession or rotational grasslands. There are four categories of PAs viz., National parks, wildlife sanctuaries, conservation reserves and community reserves. Thus, 683 PAs (102 national parks, 551 wildlife sanctuaries, 47 conservation reserves and 04 community reserves) spread over …

The Effect Of Tree Densities On The Biomass Of Leucaena Leucocephala And Chloris Gayana Using A Nelder Fan Design, Anibal Nahuel Alejandro Pachas, H. Max Shelton, Christopher J. Lambrides, Scott A. Dalzell, G. John Murtagh

IGC Proceedings (1977-2023)

Leucaena leucocephala-grass pastures are widely used for ruminant feeding in tropical and subtropical regions. In Australia, over 200,000 ha of leucaena grass pasture have been planted with more plantings expected as it is recognized as the most productive, profitable and sustainable feeding system (Shelton and Dalzell, 2007). Planting densities and planting configurations for the leucaena component vary, ranging from single or double leucaena hedgerows 3 to 12 m apart (Radrizzani et al., 2010). There is little information about how tree/grass planting configurations and resulting inter- and intraspecific competition affect above and below-ground interactions. We hypothesise that individual leucaena …
