Greenhouse Gas Emissions from Cotton Field under Different Irrigation Methods and Fertilization Regimes in Arid Northwestern China

Table 3

Effects of different irrigation methods and fertilization regimes on cotton yield and water use efficiency. Values are means ± standard deviation of three replicates. Different small letters in the same column refer to significant difference between treatments at 𝑃<0.05 level.
