| 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... |

| Twenty winter wheat varieties used as parents in a half diallel crossing programme for the production of wheat populations were grown in field trials at two organic and two non-organic sites over three years in England. Yields of the varieties between the two non-organic sites were highly correlated, but less so between the two organic sites and between the non-organic and organic sites. At the non-organic sites, most of the variation in yield (60%) was due to varietal differences, whereas, at the organic sites, it was due largely to the effects of environment (79%), and genotypic variation only accounted for 9%. More detailed analysis, using AMMI (Additive Main effects and Multiplicative Interaction), allowed stricter comparisons among individual... |
