Role Of Non-Traditional Forages In Livestock Production In India, Bhag Mal, J N. Gupta, J P. Singh
IGC Proceedings (1997-2023)
The paper reports a number of non-traditional forage species which form the life support system for grazing animals in normal conditions as well as scarcity periods like droughts and famines. Such species vary according to climatic and ecological conditions of India. These species play an important role in domestic livestock production as well as providing forage to the game animals. In the arid region the majority of such species are small trees and shrubs; in semi-arid regions majority of such species are shrubs, aquatic weeds and minor millets. In temperate/alpine Himalaya such species range from lichens, ferns, climbers to shrubs …

The Role Of Leguminous Browse Plants In A Cool Mediterranean Enviornment, P A. Lane, R Reid, D Parsons
IGC Proceedings (1997-2023)
There is considerable scope for improving the productivity and persistence of pasture systems, in the temperate low rainfall zones (< 550 mm annual rainfall) of Australia and New Zealand. Alternative pasture species, including leguminous browse plants, have potential to increase the diversity and stability of these pasture systems. The genus Dorycnium (canary clover), has previously been identified as containing a number of species with desirable forage and soil conservation characteristics. Preliminary investigations have indicated that at least two species, D. rectum and D. hirsutum, produce significant quantities of forage in the year of establishment and are palatable to sheep. It is proposed that these plants may provide a valuable source of forage on land which currently lacks productive and persistent pasture. Forage produced by these plants would be allowed …

IGC Proceedings (1997-2023)
Broadleaf birdsfoot trefoil (Lotus corniculatus L.) is a popular crosspollinated, perennial legume cultivated for pasture, or hay and silage production. It does not cause bloat and can be managed to reseed to maintain stands, but significant losses occur when stands decline from disease. Wild birdsfoot trefoil with underground rhizomes was discovered in Morocco. This paper describes research to: 1) compare the morphology and anatomy of rhizomes with aerial stems, 2) determine if rhizomes could be successfully transferred to domesticated germplasm, and 3) determine the inheritance of rhizomes. Morphological and anatomical differences between rhizomes and aerial shoots of five accessions …

General And Specific Combining Ability In Forage Maize Aptitude Part 2: Land Races, C G. Lopez, L M. Bertoia, R Burak
IGC Proceedings (1997-2023)
Eight argentine land races of maize (1 to 8) were evaluated in a diallel mating scheme for ear, stover and total digestible dry matter yield. For the average of four environments, the crosses 1x2 and 1x4 do not show significant differences with the best check (Cargill Semiden 5) for total digestible dry matter yield. Using the Gardner and Eberhart diallel analysis only the sum of squares of cultivars for stover digestible dry matter yield was significant, suggesting that additive effects are very important in controlling this trait, while for ear digestible dry matter yield both additive and non-additive effects are …

IGC Proceedings (1997-2023)
Some 285 Ladino white clover genotypes selected from four ecotypes were multiplied clonally and evaluated in a replicated pot experiment over one year. Multivariate patterns of variation were depicted by principal component analysis performed on the correlation matrix of five morphophysiological traits, namely petiole length, central leaflet size, head production, number of florets per head and stolon density. Selection was based on high broad sense heritability values of all of these traits. The level of intra-population variation was so high relative to inter-population variation that almost all plant types possibe could be found within each ecotype, although at a variable …

Legume-Rhizobia Relationship In The Nitrogen Fixation Of A New Mediterranean Pasture Legume (Biserrula Pelecinus L.), A Loi, J G. Howieson, P S. Cocks, S J. Carr
IGC Proceedings (1997-2023)
Biserrula pelecinus (biserrula) is a pasture legume of Mediterranean climates. Because of its ability to survive on acidic and infertile soils, it has been introduced to southern Australia as a potential alternative or companion plant to serradella and subterranean clover. The successful introduction of this species will be reliant upon the selection of an appropriate inoculant strain of its root-nodule bacteria and understanding of its ecology. A selection of five rhizobial strains isolated from biserrula nodules collected in Sardinia and Greece were examined for their ability to nodulate and fix nitrogen with 3 genotypes of biserrula. Although all rhizobial strains …
