Optimal Leaf Positions for SPAD Meter Measurement in Rice
The Soil Plant Analysis Development (SPAD) chlorophyll meter is one of the most commonly used diagnostic tools to measure crop nitrogen status. However, the measurement method of the meter could significantly affect the accuracy of the final estimation. Thus, this research was undertaken to develop a new methodology to optimize SPAD meter measurements in rice (Oryza sativa L.). A flatbed color ...
متن کاملdetermination of best method of partitioning n fertilizer by using leaf color chart (lcc) and chlorophyll meter (spad) in rice
in order to determination of partitioning n fertilizer by using of leaf color chart (lcc) and chlorophyll meter (spad) in rice an experiment was conducted as split plot under randomized complete block design with three replications during 2006 and 2007 at rice research institute of iran. main plots were contained cultivars in three levels (grh1, khazar and hashemi) and sub plots were contained ...
متن کاملRice Leaf Lateral Asymmetry in the Relationship between SPAD and Area-Based Nitrogen Concentration
Rice leaves display lateral asymmetry around the midrib, and the narrow side exhibits higher leaf area-based nitrogen concentration (Na) and soil plant analysis development (SPAD) values than the wider side. However, the difference in the relationship between the SPAD of each side and Na of the corresponding lateral half, and the optimal position along the leaf blade for SPAD measurements are n...
متن کاملOptimal experimental design of STEM measurement of atom column positions.
A quantitative measure is proposed to evaluate and optimize the design of a high-resolution scanning transmission electron microscopy (STEM) experiment. The proposed measure is related to the measurement of atom column positions. Specifically, it is based on the statistical precision with which the positions of atom columns can be estimated. The optimal design, that is, the combination of tunab...
متن کاملCorrection: Effects of Nitrogen Application Rate and Leaf Age on the Distribution Pattern of Leaf SPAD Readings in the Rice Canopy
A Soil-Plant Analysis Development (SPAD) chlorophyll meter can be used as a simple tool for evaluating N concentration of the leaf and investigating the combined effects of nitrogen rate and leaf age on N distribution. We conducted experiments in a paddy field over two consecutive years (2008-2009) using rice plants treated with six different N application levels. N distribution pattern was det...
