Evaluation of energy indices and greenhouse gas emissions in major horticultural crops and paddy crops in Tajan plain

Abstract One of the basic objectives sustainable agriculture is efficient use available inputs and resources. Hence, energy was evaluated in present study for cultivation greenhouse gas emissions main horticultural crops paddy Tajan. The required data were collected through relying on subjective objective methods such as questionnaries field recorded Tajan plain period 2020–2022. maximum input reported 64,867.5 MJ/ha rice, minimum amount belonging to pear 30,982.95 MJ/ha. Similarly, highest output 86,401 rice crops, lowest 30,400 pomegranate. results taken from GHG index global warming potential indicated that products including (2726.19 kg CO 2 /ha), apple (2681.6 /ha) citrus (2545.3 had impact pollution emissions. Subsequently, according regarding percentage each crop, it found out crop largest share (72,789,535.76 CO2) plain. Therefore, production with incredibly high water consumption well great chemical fertilizers old high-working hour machines have greater heating comparison other indices.
