Anthesis Dynamics, Pollen Availability And Enhancement Of Seed To Ovule Ratio In Chrysopogon Fulvus, Dunna Vijay, Chandan Kumar Gupta, D. R. Malaviya, Aniruddha Maity

IGC Proceedings (1993-2023)

Under the present scenario of severe green fodder shortage (64%) in India, grassland offers an opportunity to enhance fodder availability. To revitalize the existing denuded grasslands, seed is the best propagating material. Availability of quality seed in forage grasses is less than 20% of actual requirement/ demand. Hence, there is a need to enhance the production and productivity of grass seeds. Even the available grass seeds have very low germination percentage, which is mainly due to the absence of a caryopsis inside the fluffy seed material. Chrysopogon fulvus, commonly known as Guria grass or red false beard grass, is …

Effect Of Pretreatments On Seed Dormancy And Seedling Growth In Anjan Grass (Cenchrus Ciliaris), R. P. Nagar, S. S. Meena

IGC Proceedings (1993-2023)

Soil Seed Bank Study On Abandoned Fields And Semi-Arid Grassland, South Africa, P. J. Malan, T. Myburg, Hennie A. Snyman

IGC Proceedings (1993-2023)

Up to the 1980’s marginal soils in the central grasslands of South Africa were successfully ploughed for crop production, but unfortunately those soils soon proved to be uneconomical. Due to high input costs, low maize prices, and unreliable rainfall, the Department of Agriculture soon implemented the “soil conversion scheme” to promote the conversion of those ploughed marginal soils to permanent pastures. Regardless of the implementation the soil conversion scheme, many farmers unfortunately just abandoned some of these marginal fields, not establishing permanent pastures. This led to many hectares of unproductive previously cultivated fields, referred to as abandoned fields. It was …

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 (1993-2023)

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 (1993-2023)

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 (1993-2023)

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 (1993-2023)

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 (1993-2023)

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 …

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 (1993-2023)

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 (1993-2023)

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 (1993-2023)

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 …

IGC Proceedings (1993-2023)

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 …
