| مستخلص: |
The effects of subsequent sugarcane ratooning on soil quality and the crop yields under four treatments [an absolute control (T0), application of recommended dose of nitrogen (N)–phosphorus (P)–potassium (K) (T1), application of sulfitation press mud (SPM), a sugar factory by-product (T2), and SPM along withGluconacetobacter diazotrophicus(Gd, T3)] were evaluated for 7 years. In the control (T0) and NPK-fertilized (T1) plots, an increase in soil compaction (5.4%), decrease in infiltration rate (6.04%), lower microbial activities, and increased soil phenolic contents (72.4%) rendered the nutrients unavailable, leading to significant declines in the crop yields at the rate of 5.47 Mg ha−1y−1and 4.67 Mg ha−1y−1, respectively. The crop yield declined from 53 kg ha−1in plant crop to 18 kg ha−1in the sixth ratoon crop under the absolute control. The rates of yield decline, however, were minimized in SPM (T2) and SPM +Gd(T3) plots to 3.54 and 3.51 Mg ha−1y−1. [ABSTRACT FROM AUTHOR] |
