Seed Yield, Fodder Yield And Persistence In White Clover Cvs Of Different Origins. Results Of Trials Conducted At Lodi (Irrigated Po Valley), R Paoletti, C Locattello
IGC Proceedings (1977-2023)
White clover is the most important pasture legume in many EEC countries (white clover-ryegrass pasture system) and a good component of permanent and rotated polyphytic meadows in North Italy (irrigated Po Valley where the Ladino subspecies developed through self selection). The main characteristics of the species are N2 fixation and high nutritional value (quality). Therefore, white clover seed usage in the EEC is expected to still be important in the next decades. A number of performing varieties have recently been developed by EEC Research Institutes. An assessment of their seed production potential is necessary in view of self-sufficiency and consequent …
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 …

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), …

Freshwater snails are widely distributed in the rice field ecosystem. Freshwater snails’ feeding and metabolic activities can potentially increase the complexity of freshwater ecosystems, particularly through the nutrient cycle. Cipangopaludina chinensis, Physa acuta, and Semisulcospira libertina are commonly found in Japan's paddy field ecosystems. Spirodela polyrhiza is expected to support biodiversity, improve soil fertility, and reduce greenhouse gas emissions in paddy field ecosystems, while providing food and shelter for the snails. In this study, we investigated the effects of these three snail species on the growth of Spirodela polyrhiza. The results showed that the presence of P. acuta or C. …
