| dc.description.abstract | Field experiments were conducted in the premises of South India Paper Mill Pvt. Ltd., near Nanjangudu (12° 07' North latitude and 76° 68' East longitude) during 2013 and 2014 to study the effect of paper mill effluent (PME) on soil properties, growth and yield of rice with ten treatments replicated thrice using RCBD design. The changes in properties of soil due to continuous irrigation of PME for <5, 5-10 and >10 years to grow sugarcane were studied. Secondary treated paper mill effluent was acidic (6.26 ± 0.2) in nature, medium in electrical conductivity (1.81 ± 0.1 dS m-1), BOD load (35.2 ± 2 mg l-1) was optimum and COD load was higher (287 ± 4.2 mg l-1) but low in plant nutrients. In rice-rice cropping system treatment which received irrigation with fresh water + 150 % RDN recorded significantly higher grain (5.14 t ha-1) and straw yield (6.34 t ha-1) compared to other treatments. Significantly lower grain (4.06 t ha-1) and straw yield (5.14 t ha-1) was recorded in treatment receiving paper mill effluent + RDF. Soil properties like pH, EC, available P2O5 (63.5 kg ha-1), K2O (636.3 kg ha-1) and exchangeable Na (0.616 c mol (p+) kg-1) secondary and micronutrients content were higher in treatment receiving paper mill effluent + RDF while, the SOC (9.9 g kg-1) and available N (412.1 kg ha-1) were higher in treatment receiving paper mill effluent + 150 %RDN . In the fields irrigated continuously with PME to grow sugarcane the mean pH, EC, SOC, N, P, K, S, exchangeable-Ca, Mg, Na and DTPA- Fe, Mn, Zn, Cu and boron content in surface soils of >10 years of effluent irrigated fields were higher compared to 5-10, <5 years and control fields. The content of available macro and micro nutrients were decreased with depth. | en_US |
