Abstract:

Globally the soils are Zinc (Zn) deficient and plants are not in a position to accumulate enough Zn in edible parts that can meet the human nutrition requirement. Nanotechnology is one of the most important tools in modern agriculture. Nano agriculture involves the use of nano sized particles with unique properties (increased uptake by plants as they are small in size and have high rate of penetration through plant cell membrane) to boost crop productivity. In the present study, an attempt was made to study the effect of nano zinc oxide particle (ZnO NPs) for improving yield and Zn content in tomato plant. Initially seed priming concentration were standardized in vitro using ZnO NPs (400ppm) and granular zinc sulphate (ZnSO4) (800ppm). Further standardized seed priming concentrations with different combinations of treatment such as seed priming, seed priming+ foliar spray and foliar spray were studied under field condition to evaluate their effect on biomass and Zn accumulation The obtained results based on the physiological and yield parameters showed that the usage of ZnO NPs fertilizers through any of the method of application has significant positive effect compared to zinc sulphate. ICP-OES analysis of plant digested material revealed that uptake of ZnO NPs is higher than the granular ZnSO4. The present study addresses the potential of nano scale particles on plant system opens an avenue for its potential use as future “nano fertilizers”. Thus nanotechnology is one of technologies where lot of scope exists to improve the plant nutrition.
