Abstract:

A long-term experiment was conducted to evaluate the effect of integrated use of organic and inorganic sources of nutrients on soil quality and its relation to rice yield under Rice –rice crop rotation. A field experiment was conducted during rabi, 2015 and karif, 2016 at Regional Agricultural Research Station, Jagtial (India) on an ongoing long term (16 years) experiment which was initiated in kharif, 2000. Twelve treatments were laid out in randomized block design with four replications. The twelve treatments were 50 % NPK (T1), 100 %NPK (T2), 150 % NPK (T3), 100 % NPK + HW (T4), 100 % NPK + ZnSO4 (T5), 100 % NP (T6), 100 % N (T7), 100 % NPK + FYM (10 t FYM ha-1 in kharif) (T8), 100 % NPK –S (T9), FYM (10 t FYM ha in kharif and rabi) (T10), Control (T11) and Fallow (T12). Soil quality assessment was done by identifying the key indicators using principal component analysis (PCA) and soil quality indices (SQI). Results revealed that most of the soil quality parameters were significantly influenced by the management treatments in the experiment. In experiment, during rabi soil quality indices varied from 1.83 to 2.41 across the treatments and during Kharif season soil quality indices varied from 1.74 to 2.50 across the treatments. Nutrient-management treatments played a significant role in influencing the SQI. Among the treatments, 100%NPK + FYM resulted in a greater soil quality index (2.41 and 2.50 during rabi and kharif season respectively) followed by only FYM treatment (2.35 and 2.34 during rabi and kharif season respectively), which was at par with 100%NPK + FYM. The results indicated that the combined use of organic and inorganic fertilizers maintained higher soil quality in the soil.
