Abstract

The aim of present study to determine the suitable doses of nano iron sulphide along with nutrient management on three Brassica species. Experiment conducted at Agricultural Research Farm, BHU Varanasi which comprised 24 treatment combination involving three genotype ( Brassica juncea, Brassica carinata, Brassica napus) as main plot, nutrient level (100% RDF and 75% RDF with 25% nitrogen FYM )as sub plot treatment and three iron sulphide nanoparticles levels (0, 4, 8 and 12 ppm) as sub-sub plot treatment in split-split plot design replicated thrice during Rabi seasonof 2017–18 and 2018–19.Result disclosed that nanoparticles particle have capacity to replace chemical fertilizer and boosted the photosynthesis, net assimilation and plant relative growth. Statistical analysis of the experiment revealed that application of foliar spray of 8 ppm iron sulphide nanoparticles with application of 75% RDF with 25% nitrogen FYM in Brassica juncea significantly enhanced the LAI, CGR and RGR

Keywords

Brassica, LAI, CGR, FYM, RDF, RGR.

Conclusion

Based on the finding during the two years of investigation it could be inferred that Brassica juncea gave highest value of LAI followed by Brassica carinata and Brassica napus in all stages. Similar trend was observed in CGR and RGR value upto 90 DAS. However, it was at par with Brassica carinata at later stages. Upto harvest the trend was reversed and Brassica carinata acquired highest CGR and RGR value in both years of investigation. Among nitrogen management 75% RDF with 25% nitrogen through FYM gave higher value of LAI, CGR and RGR value during both years. Increasing concentration of iron sulphide nanoparticles brought significant increment in growth traits in comparison to water spray during both the years of experimentation. 8 ppm spray of iron sulphide nanoparticles was more efficient in producing significant changes in growth attributes followed by 12 ppm and later was at par with 4 ppm. Overall the foliar spray of 8 ppm iron sulphide nanoparticles with application of 75%
