| dc.description.abstract | Organic matter is critical to maintenance of soil fertility and productivity. Thus it is very important to understand the pools of the organic carbon and their distribution under different method of rice cultivation. The experiment was laid out in split plot design with seven treatments replicated thrice at ZARS, V.C. Farm Mandya to study the effect of different organic sources on soil organic carbon pools, nutrient content and yield of rice under flooded and aerobic system. The investigation revealed that the application of organic sources along with RDF increased the organic carbon content compared to control (only RDF). The increase was higher in flooded method of cultivation compared system. The SOC, EOC, POC, LFOC, MBC and MBN content was higher in aerobic method compared to flooded method. The labile carbon fractions viz., EOC, POC, LFOC, MBC and MBN content decreased progressively with time. The EOC, MBC and MBN content was higher in the treatment received RDF along with daincha. While POC was higher in biochar treatment. Yield of rice was significantly higher due to incorporation of organic manure + RDF compared to control. Among the organic manure higher grain and straw yield was obtained with daincha (4137 kg ha-1 and 4964 kg ha-1, respectively). The correlation between SOC with EOC, LFOC, POC, MBC and MBN was positive and significant under both the method of cultivation. | en_US |
