S1, S2, S3 and S4 = 03/21, 04/04, 04/18 and 05/02/2017, respectively.

Averages followed by the same letter in the column do not differ from each other by the Tukey test at 5% probability.

C.V. = Coeficiente of variation.

L.R. and Q.R. = Linear and quadratic regression, respectively.

∗, ∗∗ and n.s. = significant at 5, 1% and not significant, respectively.
