WebIn the United States, supply studies have usually found a strong acreage price response, but little yield price response for the major field crops. This is likely due to two factors. First, the yield response curve may be very steep over the initial range of variable inputs, but then level off dramatically. WebThe disease crown rot, caused predominantly by the fungal pathogen Fusarium pseudograminearum, is a major disease of winter cereals in many regions of the world, including Australia.A methodology is proposed, using response curves, to robustly estimate the relationship between grain yield and increasing crown rot pathogen burdens.
WebFeb 20, 2024 · For leaf rust, yield response curves are presented for the 2016 trial in Carnarvon, WA (Figure 1D). The yield loss function for leaf rust was linear, determined by the extent of disease expression. Yields of disease-protected plots were 4.2 to 5t/ha. At the highest disease burdens, the most susceptible varieties lost between 2.4 to 3t/ha. WebSimulated mean yield increased by 27% when the soil water holding capacity was increased by 25 mm, 7% when the runoff curve number was decreased from 73 to 60, 16% when soil albedo was increased from 0.2 to 0.4, and by 58% when the soil drainage factor (fraction day −1) was doubled from 0.2.
