Significant at 0.05 probability levels; significant 0.01 probability levels (P), respectively; ns, non significant at . SM, soil moisture (m³·m⁻³) determined at 0, 33, 49, 64, 84, and 120 days after sowing; F1, 0 N + 0 P; F2, 21 N + 10 P; F3, 41 N + 20 P; F4, 64 N + 25 P; 12 and 13, 2012 and 2013 crop season, respectively. SM0_F1_12 refers to soil moisture content at 0 DAS determined from F1-treated plots in the 2012 cropping season. The other abbreviations in Table 7 should be described in a similar way. ^#Found from the SMC in 2012 minus SMC in 2013 at the same sampling time.
