Abstract

Synthesized Cu–chitosan nanoparticles were assessed for seedling development in chilli (Capsicum annum L.). Ionic gelation method was used for synthesis of Cu- chitosan nanoparticles. These synthesized nanoparticles were used for seed treatment for 6hrs. Different concentrations were used for the present investigation and various growth attributes like fresh weight (in gms), shoot length (in cm), root length (in cm) and no. of leaves were recorded. Cu-chitosan nanoparticles at 50ppm has significant effect on almost all the parameters whereas concentration 800 ppm shown inhibitory effect. This is because Cu-chitosan Nanoparticles may commendably supply Cu as a micronutrient for the plants, while the abandoned application of Cu ions from the commercial fungicide constrains the vigorous growth of plants. In agricultural field, utilization of chitosan based nanomaterials especially for growth, development and protection is rare as compared to bulk chitosan. So, Chitosan based nanoparticl

Conclusion

The findings of the present study reveal that Cu-chitosan nanoparticles have potential to enhance the growth of chilli seedlings. Among the various concentrations (50 ppm) of Cu chitosan nanoparticles considered as the optimum level for the growth of Chilli (Capsicum annum L.). However higher concentration (800 ppm) of Cu chitosan nanoparticles affect the plant growth. The outcome of the present study will be useful in finding the potential of nanoparticles in crop improvement and other agricultural applications.
