Abstract

Nano fertilizers are a topic of greater interest for efficient nutrient supply and has drawn attention of the scientific community of soil and plant scientists. Currently various forms of plant fertilizers are experimented for their applicability in nano form and its influence on crops. With this background, a field experiment was conducted in the agricultural research farm of Banaras Hindu University during rabi of 2017-18 and 2018-19 to evaluate the effect of nano FeS2 on the growth and yield of Brassica sp. From the two-year experiment, it was found that nano-FeS2 significantly influenced the growth and yield of Brassica sp.and foliar application at 8 ppm at 35 DAS resulted in highest plant height, dry matter accumulation, relative growth rate, as well as seed and stover yield. Moreover, among Brassica sp., B. juncea showed superiority in terms of growth and yield over B. napus and B. carinata

Conclusion

From the results obtained based on a two-year experiment, it can be concluded that Brassica juncea showed superiority over B. napus and B. carinata in terms of plant height and accumulation of dry matter as well as test weight and seed yield, at the same time, this genotype was most responsive to the application of nano FeS2. The optimal level of nano FeS2 for foliar application was 8 ppm, regardless of the genotype of Brassica species. Additionally, the application of nano FeS2 was the most effective when sprayed at 35 DAS. This suggests that the timing and dosage are critical factors in maximizing the benefits of nano FeS2 application. However, further research is warranted to fully understand its implications and optimize its utilization in sustainable agricultural practices. Understanding the genetic and physiological factors contributing to the genetic superiority observed among Brassica sp. could facilitate the development of cultivars with enhanced resilience and productivity. Long-term studies focusing on the sustainability and ecosystem effects of nano FeS2 supplementation would provide valuable insights into its role in promoting agricultural sustainability. Exploring the potential synergies between nano FeS2 and other agronomic practices, such as integrated pest and soil health management, could offer an opportunity to enhance crop productivity and resilience in diverse agro-ecosystems
