  • Organic Society: Agriculture and Radical Politics in the Career of Gerard Wallop, Ninth Earl of Portsmouth (1898–1984)*
    AGHR53_1.qxd 10/03/2005 11:09 Page 78 Organic society: agriculture and radical politics in the career of Gerard Wallop, ninth Earl Of Portsmouth (1898–1984)* by Philip Conford Abstract Through examining the ideas and activities of G. V. Wallop, ninth Earl of Portsmouth, this article demonstrates a close connection between the emerging organic movement and radical right-wing poli- tics during the 1930s and 1940s. Evidence from his papers reveals that Wallop, a noted farmer and landowner, was instrumental in drawing together leading organic pioneers, and belonged to many of the groups which promoted organic husbandry during the mid-twentieth century. Other important organi- cists were to be found actively involved in his political initiatives, which were well to the Right of the spectrum. While rejecting the view that commitment to organic husbandry necessarily implies far-Right politics, the article argues that Wallop’s espousal of both causes casts serious doubt on the claim that the early organic movement was a-political. Many members of the contemporary organic movement, and of the Soil Association in partic- ular, experience a certain discomfort when the political dimension of its early history is discussed. Over the past two decades, several historians have demonstrated that during the movement’s formative years a number of its leading personalities were associated with Fascist or radical right-wing organisations and, in so doing, have handed ammunition to its enemies.1 Two main lines of response to the problem are evident. One is to try to drive a wedge between the organic movement as it has developed since the 1960s and its earlier incarnation from the 1930s to the 1950s, downplaying any continuity between the two and attributing the modern movement primarily to the impact of a broader environmentalism given impetus by Rachel Carson’s Silent Spring.

    KNOWLEDGE NETWORKS IN UK AGRICULTURE, 1940-85 Introduction A knowledge network, as the term is used in this paper, was the means by which scientific or technical knowledge was transferred from those who originated it to those who used or applied it. The originators were scientists, engineers and technologists, and the final users were farmers and those who worked for them. If the state requires an agricultural industry that produces more, and produces it more efficiently, and expects those output and efficiency gains to arise largely from scientific and technical changes, it should presumably, in a perfect world, invest in science to produce new technology and then ensure that farmers and their workers acquire familiarity with that new technology. There are numerous theoretical approaches to the analysis of knowledge networks, in which I include here the analysis of technical innovation, diffusion, and adoption, although it could be argued that a knowledge network is simply one part of that larger process. A crude division would be between economic and sociological models, and it is crude because many of the models analyse both economic and sociological variables, although some privilege an economic methodology while others write from a sociological perspective. Thus Hayami and Ruttan (1985) with their induced innovation concept (essentially, that technical change is a response to factor price changes) would be among the more obviously economic in approach, although they emphasise the importance of land tenure and other rural institutions (see also Koppel, 1995; Geroski, 2000). From a more sociological perspective, Oudshoorn and Pinch (2003) emphasise the role of users in constructing technical change, Clarke (1998) examines the ‘social worlds’ in which the various actors in the process of technical change interact, and Murdoch et al (2000) attempt to identify the conventions operating in a market and the ways in which they change over time in response to technical change.

  • Early History in 1919, Sir George Stapledon Founded the Welsh Plant Breeding Station, Appointing R.D

Institute of Biological, Environmental and Rural Sciences, Aberystwyth University, Gogerddan, Aberystwyth, United Kingdom, SY23 3EB Early History In 1919, Sir George Stapledon founded the Welsh Plant Breeding Station, appointing R.D. Williams as clover breeder. Williams’ early studies on clover genetics and reproduction laid the foundations that herbage legume breeding at IBERS still follow today. The population improvement programmes he instigated resulted in the development of a number of key plant varieties including the white clover varieties S100 and S184, and the red clover varieties S123 and S151. S184, bred in 1936, remains on the recommended lists for Scotland, England and Wales 83 years later. 1940s to 1950s The outbreak of World War II saw Williams was seconded to the Carmarthenshire War Agricultural Executive. This left little time for him to devote to breeding, and he died suddenly in 1943. He was replaced in 1944 by Watkin Williams and subsequently Ellis Davies in 1950. The problem of seed authentication in this time led to the development of “Nomark” strains of S100 and S123 which helped distinguish the lines from inferior strains. 1960s to 1970s Following the introduction of the NIAB recommended list for grass and clover in 1969, efforts to produce new varieties were increased with the introduction of the white clover varieties Sabeda, Olwen, Donna, Menna, Alice and Siwan, all mainstays of the early years of the recommended list, with Alice still recommended today. Red clover varieties introduced at this time included Sabtoron and the tetraploid varieties Norseman and Astra.
