Abstract/Description: | T: To evaluate the long term influence of existing soil and nutrient management practices on soil quality using Relative Soil Quality Index (RSQI) approach, two ongoing long term integrated nutrient management experiments in medium black soil (Typic Chromustert) of Bijapur centre were adopted for the study. First experiment was initiated in 1984-85 under rabi sorghum-safflower crop rotation with T1: control, T2: Sorghum- 50 kg N: 25 kg P2 O5 : 0 kg K2 O ha1 recommended dose of fertilizer (RDF), Safflower- 37.5 kg N: 50 kg P2 O5 :15 kg K2 O ha-1 (RDF), T3: 50% N (FYM), T4: 50 % N sunhemp and T5: 50% RDF + 15 kg ha-1 ZnSO4 as soil-nutrient management treatments. Second experiment was initiated in 1998-99 under rabi sorghum with T1: Control, T2: 100% N urea; T3: 25 kg N (compost); T4: 15 kg N (compost) + 20 kg N (inorganic), T5: 15 kg N (sunhemp) + 20 kg N (inorganic) and T6: 15 kg N (compost) + 10 kg N (sunhemp) as management treatments. Soil samples collected from these two experiments during 2005 were processed and analyzed for 16 soil quality indicators and Relative Soil Quality Index (RSQI) was computed. In the first set, the order of treatments from the view point of RSQI was 50% RDF + 15 kg ha-1 ZnSO4 (1.00) > 50% N (FYM) (0.97) > 50 kg N: 25 kg P2 O5 : 0 kg K2 O ha-1 (RDF for Sorghum) - 37.5 kg N: 50 kg P2 O5 :15 kg K2 O ha-1 (RDF for Safflower) (0.84) > 50 % N sunhemp (0.76). Application of 50% RDF + 15 kg ha-1 ZnSO4 to sorghum and safflower was found superior most. In the second set, application of 15 kg N (compost) + 10 kg N (sunhemp) (RSQI 1.00) was found most promising. Based on the RSQI, the general ranking was 15 kg N (compost) + 10 kg N (sunhemp) (1.00) > 15 kg N (compost) + 20 kg N (inorganic) (0.86) > 100% N urea (0.78) > 25 kg N compost (0.64) > 15 kg N (sunhemp) + 20 kg N (inorganic) (0.62). The full paper deals with the method of soil quality assessment and computation in detail. |
