Multimodel Inference for the Prediction of Disease Symptoms and Yield Loss of Potato in a Two-Year Crop Rotation Experiment

Table 3

Summed weight, 𝑣_𝑗 = Σ𝑤𝑟𝐼𝑗(𝑟), weighted regression coefficients,𝛽_𝑗, and standard errors of 𝛽_𝑗, calculated with (11)–(13) for S. subterranea in the years 1996, 1997, and 1998. Units: V. dahliae in cfu g⁻¹ soil; G. pallida, Trichodoridae, and Meloidogyne spp. in mL⁻¹ and Water soluble P in kg ha⁻¹.
