Many experimental results have shown a close relationship between total dry matter (DM) yield of alfalfa and annual evapotranspiration (ET). However, this relationship may differ from harvest to harvest (Metochis and Orphanos, 1981), indicating that water use efficiency (WUE) may vary during the growing season, particulary as it is adversely affected by high temperature (Sammis, 1981). Water for irrigating alfalfa is often scarce during the dry Mediterranean summer in Israel. Under such conditions, water is withheld for approximately two months, at a relatively advanced stage of maturity, and the crop is allowed to go to seed, after which irrigation is …

Studies On Irrigated Tropical Forage Legumes In Sudan, M.A M. Khair
IGC Proceedings (1977-2023)
The drought which had struck Sudan in the last few years had necessitated the introduction of the livestock within the farming systems of the irrigated schemes. This implies growing of enough forages in these irrigated schemes. Lablab, Lablab purpureus, clitoria, Clitoria ternatea and philipesara, Phaseolus trilobus are the most commonly grown forage legume in the Sudan. Information pertaining to the agronomy of these forages are limited in the Sudan. In this report, two ongoing experiments concerning the agronomy of these legumes are discussed. The main objective of experiment I was to study the interactive effects of seed rates and cutting …

Monitoring Annual Medicago Ley Pastures For Management Decisions, P G. Tow
IGC Proceedings (1977-2023)
The Ley Farming System of southern Australia uses a rotation of cereal and pasture comprising annual Medicago (medic) or Trifolium (clover) species. Pastures regenerate in autumn from the permeable fraclion of seed reserves. For M. truncatula cv. Jemalong barrel medic, this is about 10 % annually (Crawford, 1970). In a survey of medic persistence in South Australia, Carter (1982) found that medic seed in the top 5 cm soil was highly correlated with plant density and production potential in the following year. Seed reserves associated with 400-500 plants/m2 were classed as 'good' in commercial practice, but such cases were uncommon, …

Factors Affecting The Productivity Of Elephant Grass, G.E D. Tiley
IGC Proceedings (1977-2023)
Elephant grass (Pennisetum purpureum Schumach) is a highly productive and palatable fodder which is widely grown in the tropics (Bogdan, 1977). Optimum utilisation of its production potential is, however, limited by management factors which are associated with plant form and growth habit (Horrell and Tiley, 1970). These factors were studied in a series of trials at Kawanda Research Station, Kampala, Uganda (0°27'N, 32°30'E). A summary of the princi pal results is given.

Effect Of Fall/Winter Harvest On Alfalfa (Medicago Sativa L.) Productivity And Persistence In A Mediterranean Climate, V L. Marble, C A. Schoner Jr, G Peterson
IGC Proceedings (1977-2023)
In California alfalfa fields are grazed or harvested one or more times after the last normal season harvest (LNSH). Schoner (1981) reported that one LNSH 30 days after the last (6th) harvest reduced yield for semidonnant (SD) WL 318 and very nondormant (VND) CUF 101 9 % over three years. With two harvests, losses were similar (12 % ) for WL 318, but doubled (27 %) for CUF 101. Worker and Marble (1987) found ( 10 annual harvests) no reduction in yield, vigor or stand with either one or two fall/winter (F /W) harvests if a 45 day rest was …

Time Effect Of Top-Dressing On Yield And Quality Of Pangola Grass At Different Growth Seasons In Taiwan, Yeong-Chyn Wang
IGC Proceedings (1977-2023)
Pangola grass (Digitaria decumbens) is one of two major forage grasses in Taiwan. Usually, top-dressing of fertilizer after clipping will not be performed under no irrigation until rain comes. Thus, the dressing practice in the regeneration period is occasionally delayed several weeks just for waiting rainfall. Whether the delay of top-dressing will affect forage yield and quality of pangola grass becomes an interesting question. In order to understand the effects of time and amount of topdressing on forage yield and quality of pangola grass, a 2-year field experiment was conducted.

Autumn Management Of Lucerne, S J. Herbert, M Dempsey, D Cooley, G V. Litchfield
IGC Proceedings (1977-2023)
Past recommendations for lucernc autumn cutting management in the Northern USA have suggested a 'critical period' of 4-6 weeks growth prior to the first killing frost as necessary for long-term lucerne survival. Research had indicated that this period of growth prior to frost enabled plants to build up carbohydrate reserves to carry them through winter and provide energy for regrowth in spring (Smith, 1972). If an autumn cut was desired, it was recommended it should be taken after the killing frost so that stand vigor and longevity is maintained. Inappropriate management may reduce plant vigor, and increase susceptibility to Fusarium …

IGC Proceedings (1977-2023)
In wanner region of Japan, alfalfa growing is going to spread for the need of high quality forage. Suitable cutting frequency with an adapted variety is the important key to success of alfalfa growing in these districts. Breeding of alfalfa varieties adapted to warmer Japan started in 1964 and two varieties, Natsuwakaba and Tachiwakaba, were released from Aichi-ken Agricultural Research Center up to this time. Other promising strains are also on the breeding program. Response to cutting frequencies and persistency of these varieties were studied, and comparing with two American varieties, their adaptability to wanner region of Japan was clarified.

IGC Proceedings (1977-2023)
Napiergrass, Pennisetum purpureum (2n = 28), a robust perennial tropical cullivar, has a potential dry matter yield (DMY) of over 35,000 kg ha·1 yr·1 under intensive cutting management. Its digestibility, however, is lower than other tropical species and does not breed true from seed. Despite these drawbacks, it is a useful male parent for the development of interspecific hybrids with Pearl Millet, Pennisetum glaucum (2n = 14). Cytoplasmic male-sterile lines of Pearl Millet, crossed with Napiergrass result in an excellent interspecific triploid hybrid (3x = 21) which is seed propagated (Hanna and Monson, 1980). These triploid interspecific hybrids arc highly …

IGC Proceedings (1977-2023)
Some of the most important grassland sites in the GDR are riverside areas. Nearly two thirds of these grasslands are situated in the dike foreland, where they are often but irregularly flooded. Herc, the plant populations have been adapted to the conditions of flood and only seldom do they provide the requirements of productive cattle. Agropyron repens became the main species on numerous areas. To a high degree, yields and feed quality are influenced by time, duration and frequency of the floods and, above all, by silt sedimentation. This grassland has been investigated in model-, plot- and large scale experiments …

The present yields of meadows and pastures in the CSR are not sufficient to correspond with the needs of the advanced animal production. The varieties of species in some stands are not suitable, the stands are thin with a high proportion of weed infestation. Most frequently clovers are missing, particularly white clover. Therefore, the quality of fodder is average, there is a shortage of the energy component and often or DCP as well. The renovation of grass stands by tillage, arable farming for the period of 1-2 years and the subsequent establishment of grass stands are implemented on more fertile …

Estimation Of The Possibility Of Use Of Some Species Of Grasses For The Direct Sowing In Sward, F Bukowiecki
IGC Proceedings (1977-2023)
One of the ways of counteracting the degradation of meadow plant communities is the improvement of their botanical composition by direct sowing. In order io achieve this aim, various methods are applied: among others, sowing directly into sward (Laissus, 1984) and others. Success of sowing depends mainly on the efficiency of introduction of new grass species into the sward which is beeing degradated. That is why an attempt was made to estimate the possibility of use of some species of grasses for improvement of communities dominated by Poa pratensis on peat soils (Wizna Fen).

Alfalfa is the main forage species used in the dairy farms of the Central Valley of Mexico. Low temperatures and solar radiation during winter have been associated to the lower yields of alfalfa pastures from late fall to the end of winter. Winter pastures as annual ryegrass, small grains and common vetch can overcome the seasonal low yields of alfalfa (Victoria, 1981). Use of common vetch to provide high yields of herbage of good quality during winter has been increasing; however, availability of seed is limited. In addition, there is little published information on management of common vetch pastures for …
