Pressure on financial margins in UK wheat production is driving a review of all inputs, and seed represents one of the largest financial inputs in wheat production. The potential savings through exploiting the crop's ability to compensate for reduced

Plant characters which affect lodging in winter wheat ( Triticum aestivum L.) were investigated through husbandry-change experiments at ADAS Rosemaund near Hereford (UK) over three seasons (1994–1996). Treatments were sowing date (20 September to 1

The development of several winter and spring wheat varieties was investigated at two sites with up to eight sowing dates from 1989 to 1992. The life cycle from sowing to ear emergence was considered in phases from sowing to double ridge stage, double

A model of the wheat canopy/root/soil system has been developed, which calculates the risk of stem and root lodging from crop parameters and soil characteristics. For a large number of wind speed and rainfall realisations the model determines whether

Functions which predict rate of leaf emergence and final number of leaves, used in a model to predict the date at which growth stages occur, were tested in an experiment on winter wheat cv. Mercia grown with standardized husbandry at six sites in 199
