Abstract

In order to determine the impact of nano form ZnO priming treatments on the yield and yield-contributing characteristics of six wheat varieties, the current experiment was conducted at the Department of Seed Science and Technology, CCS Haryana Agricultural University, Hisar. WH 1184, WH 1105, WH 1124, HD 2967, HD 2851, and PBW 343 wheat varieties' seeds were primed with 100 ppm ZnO nanoparticles before sowing in the field beside a control crop that had not been treated. All the types were assessed for yield and yield-contributing traits, including test weight, grain yield, biological yield, plant height, number of effective tillers, number of grains per spike, spike length, and number of spikelets per spike. The seeds of all wheat varieties when primed with 100 ppm ZnO nanoparticles at 4 hours duration gave significantly greater plant height, number of effective tillers, number grains per spike, number of spikelets per spike, test weight, grain and biological yield than untreated seeds. The maximum increase in plant height was recorded in WH1184 (5.04%) followed by PBW343 (4.92%). The maximum increase in number of grains per spike was recorded in HD2967 (14.48%) followed by WH1124 (6.16%). The maximum increase number of effective tillers per plant was recorded in PBW343 (14.46%) and HD 2967 (14.20%). The maximum increase in test weight was recorded in WH1124 (5.14%) and WH1105 (3.66%). The maximum increase in grain yield was recorded in HD2967 (14.3%) followed by WH1184 (12.3%) that of biological yield was recorded in WH1124 (15.26%) and WH1105 (11.10%).

Conclusion

We attempted to assess the impact of ZnO NPs on wheat growth and yield in the current study. With the seed priming of 100 ppm of ZnO NPs in comparison to the control in several wheat varieties, plant growth, photosynthesis, and biomass grains all rose linearly. Therefore, administering Zn in the form of nanoparticles may aid in boosting agricultural productivity. The mechanistic understanding of the application of NPs in this field, however, may be further improved by field investigations with various nanostructure sizes, shapes, circumstances, and plants.
