Abstract
A field experiment was undertaken at the Agronomic Research Site of the Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur, Bangladesh to optimize nitrogen application in wheat field using SPAD-502 Chlorophyll Meter. Four nitrogen (N) rates from 0 to 120 kg ha-1 and different timing of N application were maintained in the experiment to test the usefulness of SPAD threshold values in decision making for supplemental nitrogen supply in wheat. A non-fertilized treatment was compared with three fertilized treatments getting 20 kg ha-1 of N at the time of crop emergence. After that supplementary nitrogen was applied to the three fertilized treatments @ 20, 40 or 60 kg N ha-1 when the SPAD values fell below the critical value of 45 SPAD (dynamic fertilization of nitrogen). Tillering of wheat plant was strongly influenced by N supply and spike bearing tillering enhanced when adequate N was applied. Application up to 120 kg N ha-1 significantly increased the plant height, total dry matter production, number of effective tillers, crop growth rate, yield contributing attributes and SPAD chlorophyll index in wheat. On the other hand, only culm reserve translocation to grain was observed higher in control and gradually decreased with increasing the levels of nitrogen. The ability of the SPAD meter to detect treatment differences due to various nitrogenous doses varied with the growth stage. The SPAD reading at all stages is positively correlated with wheat yield. Thus, the timing of nitrogen application should be closely coincided with the plant need-based to optimize the productivity of wheat.
Key Words: Nitrogen, SPAD reading, Dry matter, Culm reserve and Yield.
