From: Estimating nutrient uptake requirements for radish in China based on QUEFTS model

Radish fleshy root yield in relation to plant nutrient uptake at different (a,d) constants. The calculations excluded the upper and lower 2.5 (set I), 5 (set II), and 7.5 (set III) percentiles of all internal efficiency data (HI ≥ 0.4). YD, YA, and YU represent the maximum dilution, maximum accumulation, and balanced uptake of N, P, and K in plant dry matter, respectively. The potential yield was set at 120 t ha−1.
