Abstract
Quantification of greenhouse gas (GHG) emissions from agricultural lands is essential for strategic planning towards GHG efficient development in India. We measured the fluxes of CH4, N2O and CO2 during cultivation of two important crops; sugarcane and pigeon pea following the closed chamber technique. Both the soils acted as net CH4 sinks, but sources of N2O and CO2. Pigeon pea soil acted as a weak sink, removing 0.054 ± 0.002 kg CH4 ha−1 from the atmosphere, while sugarcane soil removed 11.061 ± 0.093 kg CH4 ha−1. Urea application in sugarcane field increased the fluxes of N2O, but the total N2O emission over growth period of sugarcane (355 days) was similar to the total emissions during pigeon pea cultivation (245 days); 2.69 ± 0.09 and 2.07 ± 0.17 kg N2O ha−1, respectively. CO2 fluxes from pigeon pea cultivation were higher than sugarcane cultivation. Pigeon pea cultivation was a low input farming, but its global warming potential was higher than that of sugarcane cultivation. This study presents the GHG estimates from cultivation of the two important crops in India for which GHG estimates are lacking.
