Developing a partcipatory approach to seed production and varietal selection Organic Eprints
Jones, H; Clarke, S M; Haigh, Z; Hinchsliffe, K; Wolfe, M S; Thomas, J; Gibbon, D; Harris, F; Lyon, F.
The performance of UK winter wheat varieties was tested under organic conditions involving farmer participation. Three breadmaking varieties (Hereward, Solstice and Xi19) and their mixture (1:1:1) were grown at 19 UK farms in 2003/04 and 2004/05. The variability of productivity on organic farms was illustrated with more variation among farm sites than among varieties. Seed health was generally high over all sites. Although the trials were successful, more time was needed at project initiation to improve farmer involvement. Some farmers expected more researcher visits, and were reticent about assessing the trials themselves. In contrast, some participants valued the variety performance data on their farms particularly when related to that of other growers....

Sustainable production of organic wheat Organic Eprints
Haigh, Z E L; Clarke, S; Hinchsliffe, K; Jones, H; Wolfe, M S.
The aim of the project is to use an ecological approach to analyse the interactions of a range of key agronomic variables in organic wheat production (wheat genotype, spatial arrangement of seed, seed density and wheat/white clover bi-cropping) to determine an optimal approach to improved and stabilised production. The fi rst set of data revealed that seedling competition was infl uenced by seed rate and drilling arrangement. Furthermore, the variety Hereward had increased emergence and establishment to Aristos. An interaction exists between wheat variety, seed rate and drilling arrangement on the level of canopy cover at different developmental stages – these factors are important for the suppression of weeds. The input of farmers in the selection of...

Using legume-based mixtures to enhance the nitrogen use efficiency and economic viability of cropping systems - Final report (LK09106/HGCA3447) Organic Eprints
Döring, T F; Baddeley, J. A.; Brown, R; Collins, R; Crowley, O; Cuttle, S P; Howlett, S A; Jones, H E; McCalman, H; Measures, M; Pearce, B D; Pearce, H; Roderick, S; Stobart, R; Storkey, J; Tilston, E; Topp, K; Watson, C A; Winkler, L; Wolfe, M S.
As costs for mineral fertilisers rise, legume-based leys are recognised as a potential alternative nitrogen source for crops. Here we demonstrate that including species-rich legume-based leys in rotations helps to maximise synergies between agricultural productivity and other ecosystem services. By using functionally diverse plant species mixtures, these services can be optimised and fine-tuned to regional and farm-specific needs. Replicated field experiments were conducted over three years at multiple locations, testing the performance of 12 legume species and 4 grass species sown in monocultures, as well as in a mixture of 10 of the legumes and all 4 grasses (called the All Species Mix, ASM). In addition, we compared this complex mixture to farmer-chosen...

Evolutionary breeding of healthy wheat: from plot to farm Organic Eprints
Wolfe, M S; Hinchsliffe, K E; Clarke, S M; Jones, H; Haigh, Z.
Genetically diverse Composite Cross Populations (CCPs) may be useful in environmentally variable low-input systems as an alternative to pure line varieties. They are formed by hybridising lines with diverse evolutionary origins, bulking the F1 progeny, and allowing natural selection of the progeny in successive crop environments. CCPs derived from 10 high yielding parents (YCCPs), 12 high quality parents (QCCPs), or all 22 parents (YQCCPs), were grown at four sites (2 organic, 2 conventional) in the UK; they are currently (2006) in F5. The YCCPs out yielded the QCCPs, which had better quality characteristics. Although the CCPs performed within the range of the parents, the values obtained were often better than the mean of the parents. Some population...

The identification and production of varieties that increase the value of oats as a profitable component of organic production Organic Eprints
Clarke, S M; Haigh, Z; Hinchsliffe, K E; Jones, H E; Wolfe, M S.
Two experiments, one comprising husked, and the other naked, oats were established at Wakelyns Agroforestry, Suffolk in October 2004 to determine traits and varieties of oats suited to organic systems, and whether growing variety mixtures conferred any advantage. Unselected F2 breeding lines were also included for selection. Husked varieties had relatively higher yields; this may have been partly the result of poor establishment in the naked varieties. Variety height was found to be an important characteristic; tall oat varieties out-yielded the dwarfs. Two of the three variety mixtures containing the naked oat variety Expression yielded 8 and 9 % higher than the average of the component varieties. The data will be verified in the second year of replicated...

The benefits of organic farming for biodiversity Organic Eprints
Norton, L R; Fuller, R J; Feber, R E; Johnson, P J; Chamberlain, D E; Joys, A C; Mathews, F; Stuart, R C; Townsend, M C; Manley, W J; Wolfe, M S; Macdonald, D W; Firbank, L G.
Previous studies suggest widespread positive responses of biodiversity to organic farming. Many of these studies, however, have been small-scale. This project tested the generality of habitat and biodiversity differences between matched pairs of organic and non-organic farms containing cereal crops in lowland England on a large-scale across a range of taxa including plants, insects, birds and bats. The extent of both cropped and un-cropped habitats together with their composition and management on a range of scales were also compared. Organic farms was likely to favour higher levels of biodiversity and indeed organic farms tended to support higher numbers of species and overall abundance across most taxa. However, the magnitude of the response differed...

Developing modern multifunctional agroforestry systems for sustainable intensification Organic Eprints
Smith, Jo; Pearce, Bruce; Döring, Thomas F.; Wolfe, M S.
Agroforestry is a land-use system that integrates trees and shrubs with crops and/or livestock production. It has been identified by the International Assessment of Agricultural Knowledge, Science and Technology for Development (IAASTD, 2008) as a ‘win-win’ approach that balances the production of commodities (food, feed, fuel, fibre, etc.) with non-commodity outputs such as environmental protection and cultural and landscape amenities. This paper will review the potential of agroforestry as part of a multifunctional working landscape in temperate regions, and will consider management and policy implications of widespread adoption of this form of land-use.

The organic seed regulations framework in Europe – current status and recommendations for future development Organic Eprints
Döring, Thomas F.; Bocci, Riccardo; Hitchings, Roger; Howlett, S. A.; Lammerts van Bueren, E.T.; Pautasso, Marco; Raaijmakers, M; Rey, F; Stubsgaard, Anke; Weinhappel, M.; Wilbois, Klaus-Peter; Winkler, Louisa; Wolfe, M S.
Organic agriculture regulations, in particular European regulation EC 889/2008, prescribe the use of organically produced seed. For many cultivated plants, however, organic seed is often not available. This is mainly because investment in organic plant breeding and seed production has been low in the past. To bridge the gap between organic seed supply and demand, national and European regulations define certain circumstances under which organic producers are permitted to use non-organically produced seed. While the organic sector currently depends on these concessions, they also threaten to impede a further increase in the demand for organic seed, thereby potentially restraining present and future investment in organic seed production and plant breeding....

Can organic farming deliver natural heritage goals in the UK uplands? Organic Eprints
Watson, C A; Chamberlain, D E; Norton, L R; Fuller, R J; Atkinson, C J; Fowler, S M; McCracken, D I; Wolfe, M S; Walker, R L.
Policy support for organic farming in the UK is based in part on the ability of organic farming systems to deliver natural heritage benefi ts. Most UK research on the natural heritage benefi ts of organic farming has addressed lowland arable systems. A reanalysis of a subset of data from a MAFF-funded study of biodiversity in England and Wales suggests that organic systems in predominantly pastoral landscapes may show similar biodiversity benefi ts to ones in predominantly arable landscapes. Future research needs to address organically managed pastoral, hill and upland systems across the UK.
