Jiang Bai-wen Yumi kexue 2011
Other claims from this paper (7)
- Method / resource Lobus leaf SPAD readings were sensitive to nitrogen at the 12, 10 and 8 leaf stages.
- Method / resource Ear leaf SPAD readings were sensitive at tasseling, filling and dough stages.
- Method / resource SPAD readings reflected chlorophyll content and total nitrogen content.
- Method / resource SPAD readings reflected maize yield.
- Method / resource The ten-leaf stage was best for SPAD evaluation of nutritional status and top dressing time.
- Method / resource The twelve-leaf stage was best for early yield prediction using SPAD readings.
- Recommendation The authors recommend SPAD readings as an index of maize yield.
