| Summary: | Application of silicon (Si) influences the stress resistance, and thereby could boost up the growth and yield of rice. Anexperiment was conducted to investi-gate the effect of Si fertilization on rice cv. Binadhan-8 at ambient and elevated temperature during Boroseason of Bangladesh. Significant differences were observed in the studied parameters: plant height, SPAD reading, yield and con-centration of NPK in grain and straw of rice. At ambient temperature (AMT) condition, plant height, SPAD reading, grain and straw yield were also the high-est in case of 10 g pot-1Si application. Moreover, the highest NPK contents in grain and straw were observed in the application of Si @ 10 g pot-1, whereas the lowest NPK contents were mostly recorded in control (0 g Si pot-1). The in-creased rate of Si contributed to the NPK absorption in grain, yield attributes and yield of rice up to 10gpot-1Si application. On the other hand, yield contrib-uting characters, grain yield and NPK uptake were showed a similar response to Si applicationat elevated temperature (ELT). But, the yield contributing charac-ters as well as grain yield at ELTshowed less performance in comparison to AMT. Therefore, the application of Si could be recommended to optimize the yield attributes, yield and NPK uptake of rice. |
