Inoculant Production With Gamma Irradiated Peat And Lyophilized Cultures Of Rhizobium. Survival On Pelleted Seeds And Mineral Oil, M Lopez, R S. Bradley
IGC Proceedings (1977-2023)
In tropical countries one of the ways of improving inoculant distribution consists on seed-pre-inoculation and on the production of lyophilized inoculants allowing a higher viability during the storage period. Thus, it is necessary to learn the rhizobium survival in pre-inoculated seeds and in lyophilized flasks, as well as in mineral oil used as a rhizobium carrier.

Environmental Considerations For Lotus Production: Seed Versus Herbage, P R. Beuselinck, R L. Mcgraw
IGC Proceedings (1977-2023)
Broadleafed birdsfoot trefoil (Lotus corniculatus L.), is recognized for good productivity on marginal soils (Seaney and Henson, 1970), high feeding value (Marten and Ehle, 1984), stock-piling efficiency (Collins, 1982) and freedom from bloatinducement in ruminants (Marten and Jordan, 1979) makes it a worthy herbage crop for many areas and grazing situations. The most productive USA areas are New England, the West Coast, the North Central Plains, and some isolated areas of higher elevations in the South (Grant and Marten, 1985). Difficulty in harvesting sufficient quantities of seed is a major factor limiting the use and production of birdsfoot trefoil in …

Agricultural Behaviour Of Lablab Purpureus Cv. Rongai Under Cuban Conditions, V A. Remy, C Matias, A Perez, M Beavogui
IGC Proceedings (1977-2023)
Production strategy of livestock in Cuba is based upon the utilization of swards as the main feeding source. Nevertheless, the climatical conditions that exist in certain period of the year lead to a seasonal productive unbalance due to the decreasing sequence of rainfall. Several alternatives have been adopted against this situation and one of them is the utilization of temporary cultivars. Taking into consideration the previous situation, the possibility of spreading Lablab purpureus, the suitable growth that it presents under temperatures among 18-30 °C (Duke, 1983), rainfall among 200-2500 mm (National Academy of Science, 1979) and its seed production from …

In ecological conditions of Yugoslavia, birdsfoot trefoil, with its positive features, presents a very significant fodder crop, especially for the hill and mountain regions. However, due to poor seed production technology, there is a shortage of seed for more intensive production. Seed is usually produced on areas intended for the production of fodder, hand sown with large quantities of seed (25-35 kg/ha). The study was undertaken. with the following targets : I/determining the influence of the manner of sowing and vegetation cycle on the yield and the quality of seed ; 2/ determining the optimum sowing manner and vegetation cycle …

Variation Of Seed Yield And Its Components In Common Vetch (Vicia Sativa L.) Under Different Conditions, E Acikgoz, I Turgut, H Ekiz
IGC Proceedings (1977-2023)
Common vetch (Vicia sativa L.) is widely used as a seed or hay crop in Turkey. In humid coastal areas it is principally used fot hay or green herbage while in dry regions it is used mostly for seed. Roughly ground vetch seed is a popular concentrated feed and mixed with straw or cereal grain (A9ikg6z, 1988). Approximately 200.000 ha of common vetch are seeded every year in Turkey. It is sown mostly as a spring-seeded crop and is often subjected to severe heat and drought stress as the season progress. Yields are generally low with an average seed …

White Clover Seed Production In Two Mediterranean Environments Of Tuscany And Sardinia, P Bullitta, Simonetta Bullitta, A Pardini, S Piemontese, P P. Roggero, P Talamucci
IGC Proceedings (1977-2023)
Purpose of the trialwas the identification of the most suitable varieties for white clover Trifolium repens L. seed production in Mediterranean environments. The main reason of this paper is to verify whether it is possible to produce seed of European varieties of white clover in south Europe considering that surfaces for seed production are decreasing in the northern European countries that were normally producers of white clover seed. The production of clover seed in southern Europe could advantageously replace the import from New Zealand and California.

Vegetative Propagation Of White Clover An Application In White Clover Seed Production, P C.D Newton, A I. Popay
IGC Proceedings (1977-2023)
Establishment of white clover for agricultural purposes is invariably by seed. However, natural regeneration is almost entirely vegetative (Chapman, 1987), and flowering may be restricted to a small proportion of individuals within a population (Burdon, 1980) When white clover is present in the soil seedbank, there is potential for both intra- (between classes) and inter-varietal contamination of seed crops. Lancashire et al., (1985) have commented that genetic contamination of white clover seed is a world-wide problem. Volunteer seedlings may be removed from between the crop rows mechanically, but there remains an untreatable area close to the crop which is available …

Viability Of Stylosanthes Seeds As Affected By Storage Duration, J B. Brolmann, B J. Boman
IGC Proceedings (1977-2023)
Tropical legumes such as members of the genus Stylosanthes (sty lo) contribute to the improvement of pastures in the tropics and sub-tropics. Stylosanthes is usually established from seed. In Florida, seed of Stylosanthes has to be produced and collected before the onset of the winter since occasional frosts can damage seed-bearing vegetation. Therefore, early maturing Stylosanthes varieties have been developed. In stylo seed collections maintained for breeding or seed exchange purposes, maintenances of seed viability is critical. New pests or new diseases may require a renewed screening of stored accessions. It is important, then, that the seed source of this …
Modification Of Stolon Growth, Development And Flowering By Plant Growth Regulators In White Clover (Trifolium Repens L.) Seed Crops, A H. Marshall, D H. Hides
IGC Proceedings (1977-2023)
Within the EEC the need to develop low cost less intensive systems of animal production has led to an increase in the importance of legumes generally, and white clover in particular. At present, annual white clover seed usage within the EEC is approximately 4,000 tonnes, however, the self sufficiency rate is expected to fall below 50 % by the end of the 1980s due principally to unpredictable seed yields which make it an unprofitable crop for seed growers. The main component of seed yield in white clover is the number of ripe inflorescences at harvest (Zaleski, 1961) however, the proportion …

Growth Regulator Effects On Seed Production Of Lotus Corniculatus L. And Lotus Uliginosus Schkuhr., J G. Hampton, Qingfeng Li, M D. Hare
IGC Proceedings (1977-2023)
Seed yield in both Lotus corniculatus L. and Lotus uliginosus Schkuhr. (syn. L. pedunculatus Cav.) is considered to be limited by the indeterminate growth habit which results in a protracted (2-4 month) flowering period (Witchwoot, 1987; Li and Hill, 1988) leading to wide variation in seed maturity and seed loss through pod shattering. In both species seed yield is determined primarily by the number of inflorescences (Mos, 1983 ; Witchwoot, 1987), and thus treatments which alter or remove apical dominance, enhance shoot production or main stem branching thereby increasing inflorescence numbers (Clifford et al., 1983 ; Li and Hill, 1988), …

China is situated in the Eastern part of Asia ; from North to South it extends across the temperate and tropical zones. From East to West it has humid, semiarid, arid regions. There is no frost through the year in some part ofHainan Island, Yunnan, Guangdong and Taiwan provinces. Therefore plants grow the year round and there is a wide range of tropical species. The geographical and climatical differences resulted in rich grass resources. There are three hundred million hectares of natural pastures in Northern China, with more than 4000 plant species. These plants have different degrees of feeding value. …

Atmospheric air cold plasma treatments (cold plasma; CP) have emerged as a promising technology in various fields, including medicine, agriculture, and environmental sciences. While CP treatment has been optimized in many fields, we lack empirical data on the efficiency and effectiveness of CP treatments in deterring insect herbivory, a recent development in CP application. Needless to say, by fine-tuning parameters such as plasma discharge method, exposure time, source gas, and input voltage, researchers can enhance the desired effects while minimizing any potential side effects. Reactive oxygen and nitrogen species (ROS and RNS) generated during CP treatments can potentially play a …

The Isolation And Characterization Of Acidovorax And Brevundimonas Bacteriophages With Preliminary Biocontrol Study On Arabidopsis Thaliana, Minh Quynh N. Vu
Senior Theses
As antibiotic-resistance becomes an increasing global concern, researchers are looking for alternatives to combat phytopathogenic rhizobacteria – one of which is through the application of phage biocontrol. To elucidate the complex tripartite relationships between phage, bacteria and plant interactions, nine novel phages were isolated from potential phytopathogenic strains of Acidovorax (RBW13) and Brevundimonas (RBW18). These phages were isolated from root samples obtained from the Rocky Branch Creek and the Broad River located in Columbia, SC. Using Pulsed-Field Gel Electrophoresis (PFGE), we identified seven “medium sized” phages (~40 kbp), one “large-sized” phage (~200 kbp), and one “small-sized” phage ( < 25 kbp). Three phages were determined to be lambda-like due to their “ladder-building” patterns on PFGE. Although spot-tests revealed that all phages seemed to have broad host ranges that spanned over multiple genera, plaque-formations must be observed in future experiments to determine if these phages can infect their hosts productively. Preliminary in planta experiments were performed on Arabidopsis thaliana …

IGC Proceedings (1977-2023)
Adaptation of berseem clover (Trifolium alexandrinum) beyond the coastal regions of the southeastern United States was limited by a lack of cold tolerance prior to the release of 'Bigbee', a selection from a stand of 'Sacromonte' subjected to temperature of -15 and -18 Con successive nights in 1972. The release of Bigbee in 1985 expanded the range of berseem clover adaptation to include the entire Southeast, as far north as Oklahoma (Knight, 1985). It is known that annual clovers do not rely on root reserve carbohydrates, but rather on residual leaf area and rapid leaf regeneration from active …

Aphelenchoides besseyi, a nematode, can infect rice resulting in the white shoot disease, which decreases the germina-tion rate and even causes seedling death. A. besseyi has recently been reported to mainly attack the organic rice varie-ties especially Pandanwangi and Ciherang in the Pasar Kawat, Beringin District, Deli Serdang, Indonesia. This research investigated A. besseyi via morphological, molecular, and morphometric approaches. The nematodes were observed in an area of 2000 m2, divided into five sample plots each with an area of 400 m2 on which Pandan Wangi and Ciherang rice were cultivated. Nematode morphology was observed using a stereo microscope at …

Grassland soils, on which the crop is managed for conservation as silage, receive large amounts of vehicle and machinery traffic : rolling and multiple slurry and fertilizers applications, plus multiple harvests, are all activities which are potentially damaging to soil and sward. A number of short-term studies in the UK (Frame, 1987 and Frost, 1988) and elsewhere (Luten and Roozeboom, 1976, and Rasmussen and M¢ller, 1981) have indicated that dry matter yield can be reduced as a consequence of stress imparted to soil by agricultural tyres. Nevertheless, there is a general lack of information on the influence of soil compaction …

Renewed emphasis has been placed on crop rotation systems that include a perennial legume. Reasons for this interest include protection of soil from erosion, protection of ground water from nitrate contamination, reduction of soil compaction, and potential for fewer inputs which could reduce costs of grain production. Barnes et al. (1985) reported that a nondormant alfalfa (Medicago sativa L.) selected for increased Nin the root and crown had similar summer herbage yield as adapted dormant cultivars, but provided 62 % more symbiotically fixed N for a following crop than dormant cultivars. If most benefit is to be derived from cultivars …
