“…Such meters have been used to estimate foliar Chl and N content in various species, such as rice (Huang et al, 2008), wheat (Le Bail et al, 2005), beans (Abdelhamid et al, 2003), and fruit trees (Schaper and Chacko, 1991). However, the literature does not address whether a Chl meter can evaluate Chl and/or N contents in tea plants.…”

A chlorophyll meter can conveniently estimate foliar chlorophyll and nitrogen (N) contents in many species. The objective of this study was to evaluate the utility of a chlorophyll meter to inform nitrogen fertilization rates of tea (Camellia sinensis L.) at different places and times. Plot-scale (5 × 20 m) experiments with three replications were conducted in 2010. Each plot was treated with 248 kg pure N ha -1 per year as urea. At the same time, a field-scale (32 ha) experiment, with the same fertilization rate, was conducted at the same plantation. Tea leaves were sampled in August and November and analyzed with a chlorophyll meter in situ and in the lab. The chlorophyll and nitrogen contents and chlorophyll meter (SPAD) readings of tea leaves in August were greater than in November, and plot-scale values were greater than field-scale values. SPAD readings could estimate the chlorophyll content of tea leaves regardless of temporal and spatial considerations. However, space and time must be considered when using SPAD readings to estimate the nitrogen content of tea leaves.

“…However, portable non-destructive meters are used successfully with many species for estimating foliar chlorophyll or N (Schaper and Chacko, 1991;Castelli et al, 1996;Loh et al, 2002;Abdelhamid et al, 2003), and allow measurement of chlorophyll or N on the same leaf over time (Yamamoto et al, 2002). These meters calculate a chlorophyll index (CI) based on reflectance or absorbance at particular wavelengths, and need to be calibrated to give an estimate of actual chlorophyll or N content.…”

“…Strong relationships between leaf N concentration and SPAD values were found e.g. in apple (Neilsen et al, 1995), in corn (Chapman and Barreto, 1997) and in faba bean (Abdelhamidg et al, 2003).…”
