Other claims from this paper (5)
- Association Excessive vegetative growth at high irrigation and nitrogen inputs produced a negative interaction coefficient for cotton lint yield.
- Method / resource A single quadratic regression expressed relative cotton yield against evapotranspiration across two soils, with R2 of 0.78.
- Association Cotton seasonal evapotranspiration increased at a decreasing rate as irrigation increased up to 119 cm.
- Observation Peak daily soil moisture depletion reached 1.07 cm near maximum cotton leaf area.
- Intervention effect Adding nitrogen improved cotton water use efficiency in some cases.
