“…But, in recent findings, there has been clear evidence of declining trends of rice and wheat yield (Chauhan et al, 2012). The demand for production of rice will endure rising in the near future due to shrinkage of cultivable land and over population growth (Alam et al, 2019b). The productivity of ricewheat system in Bangladesh is declining year after year.…”

A factorial study was carried out at Bangabandhu Sheikh Mujibur Rahman Agricultural University to determine the effect of long term fertilization on yield performance of T. aman rice and wheat. The experimental plot received different organic manures for the last 26 years . The organic manure cowdung, compost, green manure and rice straw were applied at the rate of 25, 25, 7.5 and 1.5 t ha -1 , respectively in a yearly sequence. Three levels of nitrogen viz., 0, 75 and 100 kg ha -1 for rice and 0, 80 and 120 kg ha -1 for wheat were applied. Application of nitrogen fertilizer along with organic manure significantly increased yield of rice and wheat .The highest rice grain yield was found in 2014 under the N 75 and no manure treatment, which was 6.48 t ha -1 whereas grain yield of wheat was found maximum in 2008 from the interaction of N 120 and rice straw application where yield was recorded 5.25 t ha -1 . In ricewheat cropping sequence, the plots that received no nitrogen, LPI value was less than 2 (0.80) in the observed years. When the plots were treated with nitrogen fertilizer showed LPI values > 2 in 2008, 2009, 2012 and 2013, which indicates the trend of higher productivity of land due to long term fertilization. The maximum sustainable yield index was found in rice (0.69)> wheat (0.40) with 100 kg ha -1 and 120 kg ha -1 N treatment respectively. So, Long term fertilization strategy can be effective way to improve the yield, land productivity and sustainable yield index of rice and wheat through rescheduling the rates of organic and inorganic fertilizers that ensure balanced supply of plant nutrients.

“…Studies related to methane production and emission [33,39,40] as well as methanogens and methanotrophic bacteria [41][42][43][44][45][46] and methane transformations in various environments such as wetlands are actively conducted [47][48][49][50][51]. To reduce greenhouse gas emissions, the carbon sequestration ability of the soil itself and CO 2 fixing and carbon sequestration in grassland or rice paddies have recently attracted attention [24,[52][53][54]. Paddy fields play the role of a carbon reservoir [55,56] and are one of the best ways to prevent climate change.…”

BACKGROUND: Global warming is one of the most pressing environmental issues which concomitantly complicates global climate change. Methane emission is a balance between methanogenesis and methane consumption, both of which are driven by microbial actions in different ecosystems producing methane, one of the major greenhouse gases. Paddy fields are major sources of anthropogenic methane emissions and could be compounded by organic fertilization. METHODS AND RESULTS: Literature reviews were conducted to give an overview of the global warming conditions and to present the relationship of carbon and methane to greenhouse gas emissions, and the need to understand the underlying processes of methane emission. A more extensive review was done from studies on methane emission in paddy fields under organic fertilization with greater emphasis on long term amendments. Changes in paddy soils due to organic fertilization include alterations of the physicochemical properties and changes in biological components. There are diverse phylogenetic groups of methanogens and methane oxidizing bacteria involved in methane emission. Also, multiple factors influence methanogenesis and methane oxidation in rice paddy fields under organic fertilization and they should be greatly considered when developing mitigating steps in methane emission in paddy fields especially under long term organic fertilization. CONCLUSION(S): This review showed that organic fertilization, particularly for long term management practices, influenced both physicochemical and biological components of the paddy fields which could ultimately affect methanogenesis, methane oxidation, and methane emission. Understanding interrelated factors affecting methane emission helps create ways to mitigate their impact on global warming and climate change.

“…Continuous application of chemical fertilizers is harmful for environments that's why combined use of organic and inorganic sources of nutrients is crying need for ensuring safe and quality food [9]. The addition of organic materials and N fertilizer in combination could significantly improve soil health in tropical agriculture's wetland paddy system [10]. Integrated use of organic manures and chemical fertilizers would be promising not only for ensuring greater stability in production but also for maintaining soil fertility [11].…”

Rice production has increased almost doubled over the last decade in Bangladesh as a result of additional application of chemical fertilizers and high yielding varieties. Present experiment was undertaken for elucidating the combined effect of organic materials (OM) and nitrogen (N) fertilizer on yield contributing attributes and yield of transplanted aman ( T. aman) rice. Experiment was set in a factorial randomized complete block design (RCBD) with three replications. Five types of OMs viz. RS (rice straw), VC (vermicompost), RHB (rice husk biochar), CD (cowdung) and PM (poultry manure) considering two ton carbon per hectare and three level of N viz. N0, N100 and N150 kg ha-1 were used in this experiment. Findings revealed that among the five OMs; cowdung significantly improved the studied parameters. Besides 150 kg ha-1 dose of N has pronounced effect on the grain yield of T. aman rice. In general OMs alone cannot contribute to the maximum yield and yield contributing parameters. Maximum plant height (98.5cm), no of tillers (20), no of effective tillers (18), no of grains (145.0 g), no of filled grains (138), no of unfilled grains (7.0) per panicle, length of panicle (27.5 cm), 1000-seed weight (23.65g), straw yield (8.97 t ha-1), grain yield (5.41 t ha-1) and biological yield (14.34 t ha-1) was attributed by the mixed application of PM and N150 dose of nitrogen. While maximum harvest index (45.09%) was found in the plot received RS in combination of N150 treatment and its minimum value was recorded also solely in RS treated plot. Findings suggest that the use of PM along with 150 kg ha-1 N can render superior crop growth and yield of T. aman rice.
