| Abstract: |
Methane is the second most important "greenhouse gas "contributing 15% role in global warming. Effects of seven treatments i.e. Control,
100:30:30 NPK kglha, 50:0:0 + 15 em stubble, FYM 10 tonlha, Soybean 15 days old (GM), 100:30:30 NPKkglha +nitrification inhibitor 10% neem oil (Azadimchta melia) and 100:30:30 NPK kglha +ammonium sulfate (instead of urea) from LTFf (Soil Science Division) was observed at Khumaltar. The experiment was carried out in RCBD design with four replications. The closed chamber technique was used for samples collection and analyzed in Flame Ionization Detector (FID) in the Gas Chromatography (GC). Flux was ranged from 7.14 to 49.03 kglha. /rice growing period in control and 50%N + 15 em stubble respectively. Reduction in CH4 emissions in treatments neem oil and ammonium sulfate were 33.2% and 15% respectively. Application ofFYM and stubble increased CH4 emissions by 2.3% and 46.7% respectively. Higher yield 5.31 ton /ha was in the T 12 (NH4)2 S04 treated plots and lower 3.35 tonlha was in the control plot Global warming potential was found lower in soybean, neem oil and (NH4) 2 S04 and higher in stubble, FYM, suggesting that soybean, neem oil and sulfate fertilizer can be used for reducing CH4 from rice fields. Therefore, use of such materials should be encouraged. A monitoring system for greenhouse emission is a must for reducing global warming. |
