* The relative yield increase was calculated for treatment means and in comparison
to the control without biofertilizer use but within the same inorganic fertilizer
treatment;
** RR: Recommended rate: 120-60-60 kg N-P2O5-K2O ha−1 in the DS;
90-30-30 kg N-P2O5-K2O ha−1 in the WS; *** Biofertilizer treatments are described in detail in the text. |
