Canavalia Brasiliensis: A Multipurpose Legume For The Sub-Humid Tropics, A. Schmidt, M. Peters, A. Franco, R. Schultze-Kraft

IGC Proceedings (1977-2023)

Canavalia brasiliensis Mart. ex Benth. ("Brazilian jackbean") is a weakly perennial, prostrate to twining herbaceous legume with a wide natural distribution in the New World tropics and subtropics. In comparison with C. ensiformis ("jackbean"), research reports on C. brasiliensis are scattered and restricted to studies done in Latin America. The species develops a dense and extensive, deep-reaching root system and subsequently tolerates a 5-6 month dry period. Based on studies that generally were done with only one genotype, it is adapted to a wide range of soils, including very acid, low-fertility soils. Its main use is as green manure, for …

Relative Forage Yield Of Intercropped Lucerne (Medicago Sativa L.) And Winter Forage Cereals, T. Pereyra, H. Pagliaricci, A. Ohanian

IGC Proceedings (1977-2023)

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.

The Effectiveness Of Nitrogen Rates On Winter Wheat And White Clover Bi-Cropping Grown For Silage, J. Sowiński Jun 2023

The Effectiveness Of Nitrogen Rates On Winter Wheat And White Clover Bi-Cropping Grown For Silage, J. Sowiński

IGC Proceedings (1977-2023)

Whole-crop cereals harvested for silage cover c. 500,000 ha in Europe (Wilkins & Kirilov, 2003). Generally dry matter (DM) yield of small-grain cereals is lower than that of maize. In some investigations, DM yield (of high nutritional value) reached 15 t/ha (Balsdon et al. 1997; Clements et al. 1997). Whole-crop silage produced in a bi-cropping system offers more balanced forage compared to pure cereals and legumes. Nitrogen rates can be decreased with bi-cropping. The aim of this investigation was to compare nitrogen effectiveness using two methods of winter wheat cultivation: direct drilling into stubble and bi-cropping with …

The Influence Of Winter Wheat And White Clover Bi-Cropping System On White Clover Sward Parameters, J. Sowiński Jun 2023

The Influence Of Winter Wheat And White Clover Bi-Cropping System On White Clover Sward Parameters, J. Sowiński

IGC Proceedings (1977-2023)

Whole-crop silage produced in a bi-cropping system represents a low-input forage production system (Clements et al., 1997). Depressing competition of white clover (by mowing or spraying with herbicides) when winter wheat starts its growth is necessary in this system. Winter wheat also competes with white clover during crop growth. The number of growing points as well as the length and weight of stolon are the main parameters that characterise the persistence of white clover (Jorgensen & Ledgard, 1997; Marriott & Haystead 1990). The purpose of the present investigation was to study the effects of a bi-cropping system on some …

Options For Improved Biomass Production In Feeding Systems For Dairying In High Rainfall Environments In New Zealand, John M. De Ruiter, D. R. Wilson, S. Maley, S. M. Henton Jun 2023

Options For Improved Biomass Production In Feeding Systems For Dairying In High Rainfall Environments In New Zealand, John M. De Ruiter, D. R. Wilson, S. Maley, S. M. Henton

IGC Proceedings (1977-2023)

New Zealand dairy production has expanded into marginal climates and soil types on the premise of excellent profitability and efficient utilisation of forage. Annual pasture production in the cool West Coast of the South Island (rainfall 2042-2933 mm) is15,000 kg. Increased farm production and feeding of high quality biomass, from imported feed or supplementary feed crops grown on- farm, are needed to improve milk solid output. Small plot trials with spring and early summer-sown brassicas, cereals and maize were the focus for development of systems to maximise and manage the seasonal feed supply. The effect of sowing time, fertiliser timing …

Implications Of The Use Of Grazing Sheep On Kiwi Fruit Orchard, C. H. E. C. Poli, R. C. Gomes, P. Cinel Filho, M. F. Gomes, A. Zborowki, G. Pires, J. L. Rigon Jun 2023

Implications Of The Use Of Grazing Sheep On Kiwi Fruit Orchard, C. H. E. C. Poli, R. C. Gomes, P. Cinel Filho, M. F. Gomes, A. Zborowki, G. Pires, J. L. Rigon

IGC Proceedings (1977-2023)

In the southern part of Brazil there is an important area of kiwi fruit, mainly cultivated by small farmers. The use of sheep under trees of kiwi fruits could be an interesting alternative for small farmers to reduce their mowing costs, to improve their income and to provide meat for the farmers' family. However there is a lack of information about the damage that the animals could cause to kiwi fruit plants. The objective of this study was to monitor the effect of the use of sheep on a kiwi fruit orchard.

The Effect Of Cutting Regime And Cultivar On Longevity Of Pure Lucerne Stands In Latvia, Z. Gaile Jun 2023

The Effect Of Cutting Regime And Cultivar On Longevity Of Pure Lucerne Stands In Latvia, Z. Gaile

IGC Proceedings (1977-2023)

Lucerne growing is important for high and excellent quality yields of hay or silage without application of N fertilisers, as well as for increasing crop diversity in crop rotation systems. It is comparatively expensive to establish lucerne stands in Latvia. Different aspects can affect longevity of lucerne stands: suitability of cultivar to specific conditions, soil characteristics, different stress conditions and cutting management, including frequency and height of cutting, and critical rest period in autumn (Sheaffer et al., 1988). The aim of our study was to evaluate the persistence of lucerne stands without renovation while obtaining reasonable yields.

The Input Of Forage Legumes In Sustainable Grassland Systems, Žydrė Kadžiulienė, L. Sarunaite Jun 2023

The Input Of Forage Legumes In Sustainable Grassland Systems, Žydrė Kadžiulienė, L. Sarunaite

IGC Proceedings (1977-2023)

There is increased interest in sustainable grassland systems. One step towards sustainability is expansion of legume use, because of their potential to fix and transfer nitrogen (N) to subsequent crops. However, legumes can also have negative aspects, such as difficulties in establishment (Porqueddu et al., 2003), lack of persistence, N loss (Scholefield et al., 2002) and accumulation of soil borne disease agents (Kadziulis, 2001). The large variability within legume swards and between years in pastures and leys has encouraged us to search for possibilities to achieve stability of their inputs in sustainable grassland systems.

The Interaction Of Management With Botanical Composition Of Irrigated Grass-Legume Pasture Mixtures In The Intermountain West Usa, J. W. Macadam, T. C. Griggs, G. J. Mileski Jun 2023

The Interaction Of Management With Botanical Composition Of Irrigated Grass-Legume Pasture Mixtures In The Intermountain West Usa, J. W. Macadam, T. C. Griggs, G. J. Mileski

IGC Proceedings (1977-2023)

Beef produced on semi-arid range and milk produced in confinement are the main agricultural commodities in the semi-arid western USA. The studies reported here were undertaken to determine the suitability of irrigated pasture as an alternative to traditional beef and dairy production systems. The clipping and grazing studies were not run concurrently or within the same field, but were successive steps in selecting mixtures best-suited for rotational stocking of irrigated pastures in the Intermountain West. Summaries of productivity data have been reported elsewhere (MacAdam, 2002; MacAdam et al., 2004).

Use Of Novel Spatial Presentations Of Plant Species To Improve Legume Abundance, J. M. Sharp, M. J. Jeger, R. W. Fraser, G. R. Edwards Jun 2023

Use Of Novel Spatial Presentations Of Plant Species To Improve Legume Abundance, J. M. Sharp, M. J. Jeger, R. W. Fraser, G. R. Edwards

IGC Proceedings (1977-2023)

The benefits of using white clover (Trifolium repens) in pasture grazed by sheep have been widely recognised. However, clover is considered inadequate and risky as the main source of nitrogen input, since its abundance in the pasture is patchy, low (typically less than 20%) and shows great year-to-year variation. This is thought to be due to the costs of nitrogen fixation, competition with grass, the preference for clover by sheep and patchy dung and urine deposition (Schwinning & Parsons, 1996). One possible solution may be the spatial separation of clover from grass, which would remove inter-specific competition, allowing clover to …

Italian Ryegrass And Barley Mixture For Forage Production: Effect Of Harvesting Time On Yield And Quality In Northern Latitudes, Oiva Nissinen, O. Niemeläinen, M. Kontturi Jun 2023

Italian Ryegrass And Barley Mixture For Forage Production: Effect Of Harvesting Time On Yield And Quality In Northern Latitudes, Oiva Nissinen, O. Niemeläinen, M. Kontturi

IGC Proceedings (1977-2023)

In northern latitudes forage cereal and Italian ryegrass (IRG) mixtures provide a good source of forage in situations where perennial swards have suffered winter damages (Nissinen, 1994). In this experiment harvesting time of the first cut of an IRG-barley mixture was studied to optimise the yield and quality in the growing season. The objective of the study was to assess if harvesting an IRG-barley mixture later than two weeks after heading, as currently recommended, offers benefits.

Italian Ryegrass And Whole Crop Cereal Mixture: Effect Of Sowing Rate And Maturity On Variety On Yield And Botanical Composition In Northern Latitudes, O. Niemeläinen, Oiva Nissinen, M. Kontturi Jun 2023

Italian Ryegrass And Whole Crop Cereal Mixture: Effect Of Sowing Rate And Maturity On Variety On Yield And Botanical Composition In Northern Latitudes, O. Niemeläinen, Oiva Nissinen, M. Kontturi

IGC Proceedings (1977-2023)

The profitability of a dairy farm using whole crop cereals (WCC) is better in Finland than that of a farm producing combine harvested cereals and grass silage (Turunen, 2000). The main reason for that is the decrease in the machinery costs. However, quality of the WCC yield can vary considerably depending on the ear- straw ration. This may lead to problems in feeding. In this experiment we studied the effect of sowing rate and growing time of the cereal cultivar on the botanical composition, quality and yield of the WCC harvest. The objective was to study if it would be …

The Effect Of Defoliation Interval On Regrowth Of Tall Fescue, K. A. Adamczewski, Danny J. Donaghy Jun 2023

The Effect Of Defoliation Interval On Regrowth Of Tall Fescue, K. A. Adamczewski, Danny J. Donaghy

IGC Proceedings (1977-2023)

Herbage yield, persistence and quality optimise when defoliation interval is based on physiological indicators, such as leaf regrowth stage. Examples include ryegrass (Fulkerson & Donaghy, 2001), cocksfoot (Rawnsley et al., 2002), prairie grass (Fulkerson et al., 2000) and kikuyu (Reeves et al., 1996). Yield, persistence and quality optimise because leaf regrowth stage relates closely to plant energy reserves, which generally peak as the number of live leaves/tiller maximise. More frequent defoliation than the optimum reduces energy reserves and leads to a smaller root system, fewer tillers and retarded growth rate (Fulkerson & Donaghy, 2001). Based on plant …

Yield And Nutritive Value Of Heading And Headless Sorghum X Sudangrass Hybrids In Response To Cutting Frequency, J. K. Lee, H. S. Park, Y. C. Lim, S. Seo, B. H. Paek, J. H. Fike Jun 2023

Yield And Nutritive Value Of Heading And Headless Sorghum X Sudangrass Hybrids In Response To Cutting Frequency, J. K. Lee, H. S. Park, Y. C. Lim, S. Seo, B. H. Paek, J. H. Fike

IGC Proceedings (1977-2023)

Summer annual forages contribute greatly toward solving the problem of roughage supply for cattle in Korea. These forages support high levels of dairy and beef production during hot summer months when the quality and production of perennial herbage decreases due to unfavourable climatic conditions (Olson, 1971). This study investigated the effects of cutting frequency on dry matter (DM) yield and nutritive value of heading versus headless varieties of sorghum x sudangrass hybrid.

IGC Proceedings (1977-2023)

Rising populations and incomes in developing countries are likely to double demand for livestock products by 2020 (Delgado et al. 1999). This strong demand has potential to improve profitability for farmers but will require improved animal feeding in both semi-intensive crop-livestock and more extensive livestock systems. Forages usually are the most cost-effective option to supply feed demands, particularly for ruminant-, but also for pig- and poultry- production. It is critical to select the most suitable forages for the local system and conditions. Small- and even larger-scale farmers depend heavily on advice from extension and development agencies, and from seed …

Response Of Arachis Pintoi To Grazing Intensity When Associated With Different Grasses, C. M. S. De Andrade, R. Garcia, Judson F. Valentim, O. G. Pereira Jun 2023

Response Of Arachis Pintoi To Grazing Intensity When Associated With Different Grasses, C. M. S. De Andrade, R. Garcia, Judson F. Valentim, O. G. Pereira

IGC Proceedings (1977-2023)

Lack of legume persistence is one of the main reasons for poor utilisation of grass-legume pastures in the tropics. Arachis pintoi (forage peanut) is currently the most promising forage legume for the humid tropics, mainly because of good persistence under grazing (Grof, 1985; Fisher & Cruz, 1995). The objective of this work was to show how two accessions of A. pintoi react to increasing herbage allowance levels when associated with two different grasses.

Performance Of Dual-Purpose Cows On A Native Pasture-Arachis Pintoi Association In The Humid Tropics Of Mexico, E. Castillo-Gallegos, J. Jarillo-Rodríguez, E. Ocaña-Zavaleta, B. Marín-Mejía, L. 'T Mannetje, A. Aluja-Schunemann

IGC Proceedings (1977-2023)

Native grasslands (NG) are the main feed supply of dual-purpose (DP) cows of the Mexican humid tropics. NG comprise about 85% of Paspalum, Axonopus and Cynodon species, about 5% of native legumes, mainly of Desmodium, and the remaining 10% are narrow and broad leafed weeds. Arachis pintoi (AP) is a persistent grazing tolerant tropical legume. In association with sown grasses, it has improved dry matter (DM) yield, nutritive quality of forage, and milk yield up to 9 kg/cow/day (González et al., 1996). The objective was to determine if productive performance of DP cows could be improved by …

Variation Within The Species Macroptilium Atropurpureum Regarding Adaptation To Grazing, Cam K. Mcdonald, R. J. Clements Jun 2023

Variation Within The Species Macroptilium Atropurpureum Regarding Adaptation To Grazing, Cam K. Mcdonald, R. J. Clements

IGC Proceedings (1977-2023)

The twining legume Macroptilium atropurpureum cv. Siratro was released around 1960 (Hutton 1962) and the rust resistant cultivar Aztec was released in 1994 (Bray & Woodroffe 1995). The species showed great potential for pastures in northern Australia and was planted over some 220 Kha in the 1960's and 70's. The species was high yielding and readily eaten by cattle. However, by the early 1980's the species had declined dramatically in grazed pastures. Clements (1989) showed that a major problem with Siratro was the frequency of removal of growing points. This leads to less regrowth after grazing, less seed set and …

Experiences With Establishing Legumes As Part Of A Ley Pasture In A Low-Input Farming System Of The Eastern Amazon, Brazil, S. Hohnwald, B. Rischkowsky, A. P. Camarão, J. A. Rodrigues-Filho, R. Schultze-Kraft, J. M. King Jun 2023

Experiences With Establishing Legumes As Part Of A Ley Pasture In A Low-Input Farming System Of The Eastern Amazon, Brazil, S. Hohnwald, B. Rischkowsky, A. P. Camarão, J. A. Rodrigues-Filho, R. Schultze-Kraft, J. M. King

IGC Proceedings (1977-2023)

In the Eastern Amazon extensive pasture management by smallholders can result in degradation of grassland, leading to unproductive and abandoned agricultural areas (Dias-Filho, 2003). To avoid long and costly restoration of those areas, ley-systems with alternating cropping and pasture phases might offer a promising solution. The inclusion of N-fixing legumes is seen as a suitable method to improve soil fertility during the pasture phase. As mono-cultures seem not to be appropriate, given the phytodiverse climax vegetation in the humid tropics, a combination of various shrub and herbaceous legume species is proposed. Thus, this paper tests a grass-legume mixture to replace …

The Dry Matter Yield And Nutritive Value Of Wet Tolerant Tropical Forage Legumes In Single Cropping Or Mixed Cropping With Gramineous Forage Crops In Drained Paddy Field, Manabu Tobisa, Y. Nakano, K. Okano, Masataka Shimojo, Yasuhisa Masuda

IGC Proceedings (1977-2023)

In Japan the production of rice has been controlled since the 1970's and some parts of the paddy fields have been laid off for forage production. However, in poorly-drained fields or fields with high ground water table, forage species with high tolerance of wet conditions are required. The tropical forage legumes Aeschynomene americana cv. Glenn (Glenn) and Macroptilium lathyroides (L.) Urb. cv. Murray (phasey bean) have a high wet endurance (Bishop et al., 1985; Tobisa et al., 1999) and show high dry matter productivity (Skerman et al., 1988; Tobisa et al., 1999). The objective of this …

IGC Proceedings (1977-2023)

Livestock production in semi-arid rangelands of Kenya is limited by the seasonal quantity and quality of fodder. Kirkman & Carvalho (2003) stated that these inter- and intra-seasonal quality and quantity fluctuations result in nutrient deficits that severely limit livestock production potential. The objective of this experiment was to study the effect of three forage legumes on the production of natural pastures in semi-arid rangelands of Kenya.

Desmanthus: A New Forage Legume To Improve Wool Growth In Tropical Australia, J. H. De A. Rangel, Carlos A. M. Gomide

IGC Proceedings (1977-2023)

In tropical Australia, very short and erratic wet seasons are the critical factors in determining forage growth and animal production (Wheeler & Freer, 1986). Grasses are highly susceptible to low rainfall and animal production in such conditions become strictly seasonal. Improvements in meat and wool production by the introduction of stylo species (Stylosanthes sp.) into natural grasslands have been intensively reported (Gillard & Winter, 1984). However, there are currently no suitable introduced legumes for the c.28 million ha of Mitchell grass (Astrebla spp.) plains in heavy clay soils of western North Queensland, grazed predominately by wool producing Merino …

Recent Advances In Stylosanthes Research In Tropical America, Bela Grof, Celso D. Fernandes, Jaqueline R. Verzignassi

IGC Proceedings (1977-2023)

The potential of neotropical savannas is very large for pasture-based livestock systems. There are 250 million ha of well-drained lowland savannas in the American tropics. Over 200 million ha are situated in the Cerrados region of Brazil. The Cerrados support 42% of the national herd. Although these ranges support large populations of livestock, productivity is generally low. Poor nutritive value of native pastures and monospecific swards of Brachiaria spp. is the principal cause of this low productivity, especially in the dry season when these grasslands often provide no more than 60% of the animal's maintenance requirements. The best option to …

Desmodium Velutinum: A High-Quality Shrub Legume For Acid Soils In The Tropics, R. Schultze-Kraft, M. Peters, N. Vivas, F. Parra, L. H. Franco

IGC Proceedings (1977-2023)

Drought tolerant legume shrubs can enhance the sustainability of smallholder production systems in the tropics through the provision, year-round, of high-quality feed and through their positive effect on soil. Desmodium velutinum (Willd.) DC. is one of the few shrub species that have been identified as (1) well adapted to acid tropical soils and (2) of good nutritive value (Schultze-Kraft, 1996). It is a perennial native to SE Asia and tropical Africa growing up to 3 m high, the velutinous (velvety) surfaces of its 1-foliolate leaves being a characteristic feature. It grows well on soils ranging from pH 4.0 to alkaline, …

Agronomic Evaluation Of Twenty Ecotypes Of Leucaena Spp. For Acid Soil Conditions In México, J. F. Enríquez-Quiroz, A. Hernández-Garay, A. R. Quero-Carrillo

IGC Proceedings (1977-2023)

Leucaena leucocephala Lam. (de Witt) has been shown to be a good forage producer and to posses good persistence under grazing conditions in México tolerating well the management of local cattlemen (Quero et al., 2004). The Leucaena genus is native to Central America and Mexico (Hughes, 1998), but L. leucocephala is a low producer under acid soil conditions. The natural diversity is a good source of resistance to acid soil conditions resistance and to other adverse factors. Several Leucaena accessions were evaluated for production under acid soil conditions in tropical Mexico.

Leucaena Production In Arid Botswana, F. P. Wandera, M. Karachi, S. Mangope, B. M. Lefofe

IGC Proceedings (1977-2023)

The value of browse species as a source of nitrogen for grazing animals is restricted to wet seasons, with protein deficiencies being experienced by September (in dry winter season) in Southern Africa (Moleele 1998). This is when highly productive planted browse species would become useful to supplement the protein diet requirement of grazing animals (Morris & Du Toit 1998). Further, browse species can provide partly for protein requirement of intensive production systems, such as in feedlots and dairies. This paper reports work on the introduction and screening of Leucaena for Botswana conditions.

Ensiling Characteristics And Nutritive Value Of Browse/Maize Forage Mixtures, F. B. Bareeba, H. Kato, Elly N. Sabiiti Jun 2023

Ensiling Characteristics And Nutritive Value Of Browse/Maize Forage Mixtures, F. B. Bareeba, H. Kato, Elly N. Sabiiti

IGC Proceedings (1977-2023)

The practice of growing fodder tree and shrubs is being advocated for and adopted in smallholder dairy production systems. In Uganda, Calliandra calothyrsus, Gliricidia sepium, and Leucaena leucocephala have been identified and recommended as the most suitable species (Sabiiti, 2001). However tree foliage contains toxic compounds (Lowry, 1990), which may be alleviated by ensiling. The objective of the experiment was to study the ensiling characteristics of browse/ maize forage mixtures and their nutritive value when fed to lactating dairy cows.
