marginal significanceP =0.02
crop height, number of tillers and root length, produced a marginal significance between soil textures ( P =0.02, df: 3, 212, F value: 4.96, F critical: 2.64, single factor ANOVA), with clay loam soils having the greatest reduction to crop biomass ( P =0.02, df: 69, t.stat: 2.14, paired unequal variance post hoc T test).
