Figure 3
Average nutrient content of the shoot (g kg−1 plant−1) of the arabica coffee cultivars Catuaí-Amarelo/IAC-62 and Catuaí-Vermelho/IAC-144, cultivated in soils with different levels of P and subjected to subdoses of glyphosate at 90 days after application. (a,g) Nitrogen; (b,h) sulfur; (c,i) calcium; (d,j) phosphorus; (e,k) potassium; and (f,l) magnesium. For each nutrient, same lower-case do not differ between the soil P contents, and same upper-cases do not differ between the glyphosate subdoses by the Tukey test at 5% probability. ± Vertical bars indicate the standard deviation (n = 4). Plots were drawn using SigmaPlot ver. 10.0 (Systat Software, Inc., San Jose, USA, www.systatsoftware.com).
