Nitrogen mineralisation rates from chicory-based pastures

Matthew Gardner, Jason Condon, B. S. Dear, M. K. Conyers et autres

The incorporation of chicory (Cichorium intybus) into phased crop-pasture farming systems requires an understanding of the dynamics of nitrogen (N) mineralisation of residues and the potential supply of N to subsequent crops. A 3-year field experiment was conducted to compare relative N …

Chicory stimulates companion legume species to fix more biological nitrogen

Matthew Gardner, Jason Condon, Mark B. Peoples, M. K. Conyers et autres

Abstract Purpose Chicory (Cichorium intybus) scavenges more soil mineral nitrogen (N) than perennial ryegrass (Lolium perenne). A glasshouse study was conducted to test whether (a) the percentage of N derived from the atmosphere (%Ndfa) by a companion legume differs when grown with …

Comparison of nitrogen mineralisation patterns of Cichorium intybus and Medicago sativa

Matthew Gardner, Jason Condon, B. S. Dear, M. K. Conyers et autres

Abstract Little is known about the rate of mineralisation of chicory ( Cichorium intybus ) residues and how this may influence the availability of nitrogen (N) for subsequent crops. An incubation study was conducted to compare the relative rates of N mineralisation …

Genetic Diversity and Lineage Based on SSR Markers of Two Genomic Resources among Trifolium Collections Held within the Australian Pastures Genebank

D. R. Malaviya, Harsh Raman, B. S. Dear, Rosy Raman et autres

Trifolium alexandrinum, an important forage legume, suffers from narrow genetic base. The present investigation was envisaged to reveal the inter- and intra-species genetic diversity and lineage among 64 accessions, representing a global collection, of T. alexandrinum; it’s two probable progenitor species (T. …

Time of sowing and the presence of a cover-crop determine the productivity and persistence of perennial pastures in mixed farming systems

Guangdi Li, Richard C. Hayes, Jeffrey McCormick, Matthew Gardner et autres

Incorporation of perennial pastures into cropping rotations can improve whole-farm productivity, profitability and sustainability of mixed farming systems in southern Australia. However, success in establishing perennial pastures depends on choice of species, time of sowing, method of establishment, seasonal conditions, and whether …

Farmer experience with perennial pastures in the mixed farming areas of southern New South Wales: on-farm participatory research investigating pasture establishment with cover-cropping

A. D. Swan, Mark B. Peoples, Richard C. Hayes, Guangdi Li et autres

In 2009, 95 farmers in the mixed farming zone of southern New South Wales (NSW), average annual rainfall 450–700 mm, were surveyed about their use of perennial pasture species. Survey responses indicated that, on average, 52% of land was under crop, 29% …

Mineralisation of chicory and lucerne residues under field conditions

Matthew Gardner, Jason Condon, Guangdi Li, M. K. Conyers et autres

The incorporation of chicory into phased farming systems requires an understanding of N mineralisation of chicory residues and the supply of N to subsequent crops. A field experiment was conducted to determine the relative rates of N mineralisation from chicory, chicory/subclover and …

Evaluating the importance of a potential source of error when applying shoot 15N labelling techniques to legumes to quantify the below-ground transfer of nitrogen to other species

Matthew Gardner, Mark B. Peoples, Jason Condon, Guangdi Li et autres

Different 15N-based shoot-labelling protocols have been utilised to quantify the below-ground transfer of N between pasture or crop species. The most straight forward and effective 15N-labelling technique appears to be shoot labelling via leaflets or petioles. This paper reports a time-course study …
