Abstract

The field experiment conducted during the rabi season of 2021-22 at the Agricultural Research Sub-station in Vallabhnagar, Udaipur, Rajasthan, aimed to assess the influence of zinc-based fertilizers on the growth characteristics and distribution of zinc fractions in the soil of barley (Hordeum vulgare L.) crop. The experimental design followed a split plot arrangement, with main plot treatments consisting of a control, 5 kg Zn per hectare as soil application, and seed treatment with zinc solubilizing bacteria (ZSB) at a rate of 5 ml per kg of seed. The sub plot treatments included a control and three foliar sprays of nano Zn at 5 ml per litre of water, applied at 15, 30, and 45 days after sowing. Each treatment was replicated three times. The soil application of zinc @ 5 kg Zn ha-1 along with foliar spray of nano Zn @ 5 ml per litre of water at 45 days after sowing had significantly influenced plant height and dry matter accumulation at 60 DAS of barley as well as zinc fraction of soil after harvest of barley crop. the combination of conventional zinc fertilizer and foliar spray of nano zinc offers a promising strategy to improve nutrient availability and enhance zinc fraction distribution in the soil after the barley crop's harvest. This approach holds potential for optimizing zinc uptake by barley plants and promoting sustainable agricultural practices in regions with zinc-deficient soils.

Conclusion

From the forgoing result, it was concluded that the combined application of the conventional and nano fertilizers significantly alters the growth parameter of barley and distribution of zinc fractions in post-harvest soil of barley crop. The combined application of conventional zinc fertilizer and nano zinc fertilizer can potentially enhance the distribution and availability of zinc fractions in the soil, providing an improved nutrient supply for plants and supporting their growth and development. The synergistic effect of both fertilizers can result in improved solubility, mobility, and bioavailability of zinc in the soil, leading to enhanced zinc fractionation. The combined application of conventional zinc fertilizer and nano zinc fertilizer demonstrated promising results in altering growth parameters of barley and influencing the distribution of zinc fractions in post-harvest soil. This approach has the potential to enhance nutrient availability, promote plant growth, and optimize nutrient management practices in agricultural systems.
