Crop residue incorporation combined with potassium fertilizer increased cotton canopy apparent photosynthesis and seed cotton yield in barley-cotton rotation system

Potassium (K) is indispensable for cotton (Gossypium hirsutum L.) cultivation. The objective of this study was to evaluate the effects of crop residue incorporation and K fertilizer on seed cotton yield, K uptake and canopy apparent photosynthesis. Thus, we conducted a three-year experiment, using a split-plot design.
