The Effect Of Sowing Date And Autumn Management On Sainfoin (Onobrychis Viciifolia) Regrowth And Yield, Z. G. (Zhigang) Liu, G. P. F. Lane
IGC Proceedings (1997-2023)
Due to its characteristics (palatability, non-bloating, high protein, high voluntary intake etc.: Frame, 1998), sainfoin was a traditional forage legume in the UK, grown widely during the 17-19th century (Bland, 1971). It has almost disappeared in recent years. The rise of organic farming and the need for home-grown protein may encourage the return of sainfoin. This experiment aimed to explore the impact of sowing date and autumn management on the growth and yield of sainfoin in UK.

Rangelands In The Mediterranean Zone Of Croatia, J. Rogosic
IGC Proceedings (1997-2023)
Rangelands dominate the landscape of the Mediterranean part of Croatia along the Adriatic coastline, occupying 83% of the agricultural land (1.7 million ha) and 40% of the entire country. The proportion of rangelands is considerably higher in the Mediterranean littoral than in other ecological regions of Croatia. Sheep and goats are widespread in the region, comprising 76% of total sheep and goat numbers in Croatia. However, in comparison to other regions of Croatia, livestock production in the Mediterranean zone is not well developed. Continuous grazing begun too early in the growing season has caused substantial rangeland degradation and a decline …

Long-Term (9-Year) Response Of Two Semiarid Grasslands To Prescribed Fire In The Southwestern Usa, R. L. Pendleton, B. K. Pendleton, C. S. White
IGC Proceedings (1997-2023)
Historically, arid grasslands of SW USA experienced fire return intervals of 5-10 years. During the last 100 years, however, fire has been a rare event. Recent expansion of woody plants in arid grasslands has prompted managers to re-introduce fire as a tool to reduce abundance of woody plants and maintain perennial grass cover. The use of fire in desert grasslands poses unique challenges, however, due to extreme variability in rainfall patterns. Our research examines vegetation response to repeat fire in 2 desert grassland ecotones near Albuquerque, New Mexico (35.05o N 106.60o W).

Studies On Rehabilitation And Recovery Of Degraded Shrub Rangeland In Central China, G. Xiao
IGC Proceedings (1997-2023)
Central China used to be the most important region for animal production, but over-grazing, over- cultivation and deforestation all resulted in a decline in shrub rangeland productivity as well as increasing soil degradation (JiZhou, 1989). Soil erosion, salinisation and desertification have become serious problems. The productivity of shrub rangeland decreased from 3,000~4,000kg/ha to 1,500~2,000kg/ha from the 1960s to the 1990s (Wei, 1991). Since 1990, measures have been taken to solve this problem with promising results.

Reasons For The Premature Decline In Astragalus Adsurgens Stands In Kerqin Sandy Land, Qizhong Sun, Z. L. Wang, J. G. Han, Y. W. Wang, G. R. Liu
IGC Proceedings (1997-2023)
Diseases partly account for reductions in Astragalus adsurgens stand longevity. The effect of some cultural practices on the control of pests and diseases have been reported (Hou, 1986; Nan, 1996), but few reports have detailed the relationship among soil fertiliser status, diseases and premature stand decline. This study was conducted to investigate these relationships in order to extend the longevity of Astragalus adsurgens stands.

Tiller Dynamic Of Guineagrass (Panicum Maximum) Under Defoliation, T. Clavero, R. Razz
IGC Proceedings (1997-2023)
Guineagrass (Panicum maximum) is a perennial warm season bunchgrass native to Africa that has been introduced to many tropical areas. Its management is important because of its important role in animal production. Total production of herbage and the persistence of tufted grasses can be markedly reduced when the grass is defoliated too frequently and too intensively (Clavero, 1997). In order to determine the proper management for optimum production and long term persistence, it is important to study the effect of cutting practices on tiller dynamics of guineagrass.

Effect Of Plant Population And Phosphorus Fertilizer Application On Dry Matter And Seed Yield Of Two Lablab (Lablab Purpureus) Varieties In Botswana, K. C. Kawonga, F. P. Wandera, S. Mangope, P. Mutshewa, B. M. Lefofe
IGC Proceedings (1997-2023)
Lablab has high potential as a protein source to grazing livestock especially during the dry season in arid Botswana. It produced 8.5t dry matter (DM)/ha and had 14% crude protein with 60% digestibility (APRU, 1988; Aganga, 2003). Lack of agronomic data on lablab production was probably the reason why some farmers in Botswana got yields as low as 300 kg/ha (APRU, 1987). Therefore, a trial of two lablab varieties was conducted to determine the effect of plant population and phosphorus (P) on DM yield.

IGC Proceedings (1997-2023)
Pasture forage production is based on the growth of tillers (Hodgson, 1990). Although the effect of canopy height and structural traits on productivity of temperate grasses are well known e.g. (Bircham & Hodgson,1983; Binnie & Chestnut, 1994) tiller studies on tropical pasture species are scarce.

Integration Of Forage Production In Rice-Based Cropping Systems For Mitigating Forage Crisis Of Ruminant Livestock - Studies In Bangladesh, M. A. Akbar, M. S. U. Bhuiyan, M. S. Islam
IGC Proceedings (1997-2023)
Intensive rice cropping in Bangladesh is causing alarming shortages of forage and low ruminant productivity. This is also causing degeneration of soil fertility. Therefore it is imperative to identify some approach to integrate fodder production into rice cropping systems on rural farms. The integration of legume forage may improve soil fertility and soil structure, thus enhancing crop yield and may provide high quality feed for livestock (Haque 1992). Studies were done to investigate the effects of rice/forage integration on forage yield, soil fertility and also on milk yield of cows fed on the grown forages.

Evaluating The Economic And Environmental Sustainability Of Integrated Farming Systems, C. A. Rotz, M. A. Sanderson, M. Wachendorf, F. Taube
IGC Proceedings (1997-2023)
Economic and environmental sustainability has become a major concern for forage-based animal production in Europe, North America and other parts of the world. Development of more sustainable farming systems requires an assimilation of experimental and modelling research. Field research is critical for supporting the development and evaluation of models, and modelling is needed to integrate farm components for predicting the long-term effects and interactions resulting from farm management changes. Experimentally supported simulation provides a tool for evaluating and comparing farming strategies and predicting their effect on the watershed, region and beyond.

IGC Proceedings (1997-2023)
In southern Australia, 50% of grain-producing farms also run beef and/or sheep enterprises. Legume pasture leys are used to replace soil nitrogen and manage crop disease risks. Deep-rooted perennials, predominantly lucerne (Medicago sativa), are replacing annual Trifolium subterraneum-based leys to increase pasture production. They also have the environmental benefits of limiting soil acidity, rising water tables and dryland salinity. After recent droughts depletion of soil water by lucerne has penalised wheat yields. Decision support tools can help farmers evaluate the long-term effects of grazed annual and perennial leys on animal and crop production at the whole farm …

Overseeding Cereal Rye And Annual Ryegrass Into Soyabean For Forage As Part Of A Multifunctional Cropping System, L. B. Smith, R. L. Kallenbach
IGC Proceedings (1997-2023)
In the lower Midwest, the longest period of inadequate forage supply from pasture is from mid- December through mid-March (Matches & Burns, 1995). Livestock producers in this region are looking for high quality forage for winter grazing (Kallenbach et al., 2003). Annual ryegrass (Lolium multiflorum Lam.) and cereal rye (Secale cereale L.) are two forages that Missouri's beef producers are interested in to extend the grazing season. The objective of this research was to determine how seeding date impacts the establishment, growth, and forage production of annual ryegrass and cereal rye when planted into soyabean fields …

Previous Grass-Lucerne Mixtures Affect Barley Yield And Quality In A Semiarid Location Of The Canadian Prairie Region, P. G. Jefferson, F. Selles, R. P. Zentner, R. Lemke
IGC Proceedings (1997-2023)
In the semiarid region of the Canadian prairies perennial forages are not rotated with annual crops because previous experiments reported negative impacts (Kilcher and Anderson 1963; Campbell et al. 1990). However, previous research used persistent species while short-lived species could have less adverse effect. Our objective was to compare three grass species in three lucerne mixtures terminated with tillage or herbicide for effects on barley grain, N concentration, and N uptake.

IGC Proceedings (1997-2023)
In tropical regions of the world intercropping is mainly associated with the production of maize for grain, while in temperate areas it is associated with the efficient production of forage. There is increasing interest in the development of cereal - legume intercropping in some temperate regions (reviewed by Mason & Pritchard, 1987). The aim of this study was to compare the relative forage yield of intercropped lucerne and cereal.
