The present research will focus only on the intangible heritage of Comilla district to determine, classify and investigate the recent degradation of its glories. Various intangible heritages are determined with their types, features, style, uses, and make a relation between the local people and the intangible heritages. This district is considered as a base point of pre-historic culture to early-historic Buddhist religious complex. Besides historical value this region is a land of intangible heritage. According to the index of UNESCO we have determined a large number of intangible heritages in this region. The styles of language, oral literature, folk literature, sports, body techniques, empirical knowledge and culinary techniques are the important intangible heritage of this district nay of the Bangladesh. Some times few of them were documented but many of them are still now not documented. By the influence of various natural and cultural phenomena this heritage are strongly treated. Cultural standardization, globalization, tourism, migration, industrialization, urbanization deterioration of cultural environment are the main key factor to modify characters. UNESCO has taken some project to protect the intangible heritage but this area has denied several times. So this will be better option for UNESCO or other organization (Govt. or Non-Govt.) to protect them by declaring “Master Piece.”

Winter cover crop cultivation is recommended to improve soil carbon sequestration and quality. However, its biomass addition as a green manure can significantly increase methane (CH4) in rice paddy soil. There are many soil management practices to reduce CH4 emission in rice paddy soil, but the intermittent drainage is regarded as a key soil management to reduce CH4 emission during rice cultivation. However, it is expected to increase significantly carbon di .oxide (CO2) emission. In this study, the effect of a 30.day intermittent drainage from the 20th day after transplanting (DAT) to the 50th DAT on two greenhouse gas (GHG) fluxes and yield properties were compared with those of a continuous flooding system under different rates of cover crop biomass addition during rice cultivation. The biomass of cover crop which cultivated during the fallow season on site was applied with the different rates (0.100%) of total biomass (12 Mg ha.1 on dried weight). Methane and CO2 gas samples were collected simultaneously twice a week by two different pairs of closed chamber. The effect of intermittent drainage on changing two GHG emissions were compared using the GWP value which was calculated as CO2 equivalents by multiplying 25 to the seasonal CH4 flux. Methane and CO2 emission rates were significantly (p<0.05) increased with increasing application rates of cover crop biomass in both irrigation treatments. The intermittent drainage effectively reduced seasonal CH4 fluxes by ca. 51% to that of the continuous flooding under total biomass removal, but its effect was significantly increased under higher biomass application. The intermittent drainage reduced around 69% of total CH4 flux under total biomass recycling, but increased CO2 fluxes by 18.20% under the same levels of biomass addition. However, the intermittent drainage significantly reduced the total GWP value, and its effect significantly increased under higher biomass addition from 66% to 77%. There was no significant difference in terms of rice yield either in continuous flooding or intermittent irrigation under the same fertilization background. In conclusion, the intermittent drainage could be a good soil management strategy under high levels of biomass addition to reduce GWP value by suppressing effectively CH4 emission.

Many researchers have documented that rice-mediated transport is the major pathway potentially accounting for more than 90% of the total CH4 emitted from soils over the growing season. However, characterization of the individual CH4 transport like ebullition as gas bubbles and rice plant has not been well elucidated in green-manure amended mono-rice paddy soil. A mixture of barley (75% of the recommended dose, RD), and hairy vetch (hereafter, vetch, 25% of the RD) seeds were broadcasted after riceharvesting in the experimental farm of Gyeongsang National University (36o 50` N and 128o 26` E), Jinju, South Korea, and the above-ground biomass (34-36 Mg ha-1 with 67-69 % moisture content) were harvested before rice transplanting in 2011 and 2012. The fresh biomass was chopped in a 5-10 cm length and incorporated with different ratios (0-100%) one week before ricetransplanting under the same chemical fertilization (N-P2O5-K2O= 90-45-58 kg ha-1). The combination of cover crop biomass was applied at the rate of 0, 9, 18, 27 and 36 Mg ha-1 on fresh weight basis to investigate their effect on CH4 emission through direct ebullition from the soil and rice-mediated transport during rice cultivation. With increasing biomass application, the plant-mediated CH4 transport sharply increased until the vegetative stage of the plant, while CH4 emission through direct ebullition from soil was higher at the reproductive stage of the plant than plant-mediated transportation. Our result predicts that ca. 9 and 91% of CH4 emitted through plant-mediated transport and direct ebullition, respectively in paddy soil applied with green manure applications. Incorporation of cover crop biomass at 9 Mg ha-1 was optimum for the reduction of CH4 emissions in soil and its increased application can significantly increases CH4 emission during rice cultivation.
