Effects of long term application of inorganic and organic fertilizers on soil biological properties of rice

Author(s): S Bhavani, K Chandra Shaker, G Jayasree and B Padmaja
Abstract:
Long Term Fertilizer Experiments were conducted since kharif, 2000 at Regional Agricultural Research Station, Jagtial, Professor Jayashankar Telangana State Agr4icultural University in rice – rice cropping system on an Inceptisol. The present study was undertaken during kharif, 2016 to estimate the soil biological properties (urease, dehydrogenase and phosphatise activity) at different growth stages of rice. In all the treatments, enzymes exhibited higher activity at flowering stage (60 DAT) and thereafter the activity was decreased towards 90 DAT. Continuous application of FYM along with balnced fertilizer application i.e. 100 % NPK recorded highest urease and dehydrogenase activity during both the stages of crop growth. Super optimal dose of NPK (150 %NPK) recorded significantly higher acid and alkaline phosphatase activity, whereas this activity was comparable with 100 % NPK + FYM treatment. Integrated nutrient management practice including FYM and recommended dose NPK showed as best treatment with respect to increase enzymatic properties.
