Assessment of Greenhouse Gases Emission in Maize-Wheat Cropping System Under Varied N Fertilizer Application Using Cool Farm Tool

In recent decades, climate change induced by enhanced global warming is one of the biggest challenges at level. Agriculture sectors significantly contribute to total anthropogenic greenhouse gas emission atmosphere. Wheat and maize, cultivated globally, consumed in different forms, are considered as crucial staple cereal for ensuring food security population. The management practices involving land preparation, sowing, fertilizer application, irrigation, pest management, etc. influence carbon dioxide (CO 2 ) nitrous oxide (N O) from agricultural soil. this study, CO N O were assessed maize wheat crops four levels using cool farm tool model. Emissions per hectare varied 331.4 1,088.3 kgCO ranged 292.3 765.3 on application doses N. GHG 859.5 3,003.4 eq with nitrogen varying (0–240 kg hectare). highest efflux (0.368 ton) was observed 240 under crop. on-farm emissions, through production, account about 33.7%, contributes only 65.9%, whereas pesticides merely 0.4% maize-wheat cropping. This study confirms that direct totally dependent fertilizers rate; however, indirect controlled fuels energy consumption.
