IGC Proceedings (1977-2023)

The increasing rate of woody plant encroachment in grasslands or savannas remains a challenge to livestock farmers. The causes and control measures of woody plant encroachment are of common interest, especially where it negatively affects the objectives of an agricultural enterprise. The objectives of this study were to determine the effects of gut passage (goats, cattle), dung (nutrients), fire, grass competition and trampling on establishment of A. nilotica (Fabaceae) and D. cinerea (Fabaceae sub family Mimosoideae) seedlings. Germination trials were subjected to: 1) seed passage through the gut of cattle and goats and unpassed/ untreated seeds (i.e. not …

Morphofunctional Diversity Of Diaspores Of Some Range Grasses Of Punjab (India), Amarjit Singh Soodan, Sushant Sharma, Ashok Kumar, Rajdavinder Kaur

IGC Proceedings (1977-2023)

Grasslands occupy almost half of the terrestrial expanse of India ranging from coastal to alpine regions. Whyte (1958) defined ‘grassland as the land on which graminaceous species represent the dominance if not the exclusive vegetation’. Grasslands comprise the main source of fodder for the 500 million cattle population in the country besides providing habitat to several plant and animal species. But the grasslands are shrinking due to the pressure of intensive agriculture and urbanization not only in expanse but also in their biodiversity. In this context there is an urgent need to develop not only a policy towards a sustainable …

Seed Shedding Of Lolium Multiflorum In Dependency On Application Of Preparations Controlling Plant Ripening Process, Barbara Golińska, Piotr Goliński

IGC Proceedings (1977-2023)

The seed shedding susceptibility is specific biological feature of grasses (Hampton and Fairey, 1997; Simon et al., 1997), which occurs particularly in the species of Lolium-Festuca complex. Lolium multiflorum is a grass distinguished by highest susceptibility of seed shedding (Golińska, 2009). It is the main reason of up to 60% of seed yield losses during harvest of seed plantations of this grass (Coolbear et al., 1997). In order to prevent seed losses by shedding the investigations are necessary to improve the efficiency of grass seed production. One of the possibilities is using of preparations which physically or physiologically …

IGC Proceedings (1977-2023)

The rye (Secale cereale L.) has been used as an excellent green manure crop and good forage crop in Korea. The rye is usually recommended as a winter crop for forage and green manure after either maize or rice in Korea (Heo et al., 2009). But most of its seeds are being imported from foreign countries because the seed productions have difficulty with latematuring and the heavy raining season in the ripening stage in Korea. Therefore, a new rye variety “Gogu” with an earlymaturing and high performance was bred by National Institute of Crop Science (NICS), Suwon, Korea in …

Seed Standards And Seed Testing Protocols For Forage Legume Seeds, Vinod Kumar, K. Sridhar

IGC Proceedings (1977-2023)

Seed is the basic agricultural input and its quality is extremely important. In the absence of seeds of assured quality, the expenditure of the farmers on the other inputs may become of little use. It was in this context, seed legislation is in force in majority of the crops cultivated across the country to ensure the availability of high quality seeds to the farmers. The seed quality parameters (known as Indian Minimum Seed Certification Standards, IMSCS) of a notified variety of various crops (viz., forages, cereals, millets, pulses etc.) have been published through Gazette notifications by the Government …

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 …

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.

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 …
