Yield and gas exchange of greenhouse tomato at different nitrogen levels under aerated irrigation

In a research conducted by Ya-Dan Du et al., the relationship between yield and gas exchange of a tomato greenhouse at different nitrogen levels and under aerated irrigation. The study was done during Spring and Autumn cultivation periods in Yangling, China with five N application rates (0, 50, 150, 200,250 kg ha−1) and two irrigation methods (AI and conventional irrigation [CK]). The results indicated that AI and N application both increased tomato yield, but also increased soil CO2 and N2O emissions.

The researchers concludes "that in a future warmer climate, reducing nitrogen fertilizer rate in conjunction with the use of AI will remain important practices for maintaining crop yield while reducing soil net greenhouse gas emissions."
