Sowing date and seed rate influence crop establishment, growth, yield and profitability. The growth and yield of field beans (Vicia faba) in response to sowing date and seed rate was examined over three seasons, 2016–2019, in Teagasc, Oak Park, Car

SUMMARYThe effects of the anti-gibberellin triazole metconazole on yield, lodging resistance, seeds/m2 (sink size) and rooting in the presence of negligible amounts of disease were investigated using five multi-site experiments carried out in the UK

Source or sink limitation of grain filling in cereals is often inferred from experiments in which the source:sink ratio is manipulated by shading, defoliation or grain removal. However, interpretation of this type of experiment is usually qualitative

The results of recent trials for winter wheat (Triticum aestivum L.) have influenced farming practice in the UK by encouraging the use of lower seed rates. Spink et al. (2000) have demonstrated that, particularly if sown early, wheat can compensate f

One winter wheat variety, Soissons, suffered extensive frost damage in a plant population density (PPD) and sowing date (SD) experiment in 1997/1998. Another variety, Cadenza, did not incur any frost damage, even though it was at a similar developmen

This paper describes how an existing model of lodging in winter wheat (Triticum aestivum L.) has been further developed to enable it to predict the timing and amount of lodging from inputs about the crop, soil and weather. Improvements include the us

The total dry matter in non-surviving shoots and the amount of this contributed by their own carbon fixation was quantified for four winter wheat cultivars in two UK field experiments in 1995–1996 and 1997–1998. Amongst the cultivars studied (Bri

Summary The effects of reducing the plant density of winter wheat (cv. Haven) on canopy formation, radiation absorption and dry matter production and partitioning were investigated in field experiments in 1996/97 and 1997/98. Crop densities establish

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
