Abstract

A field experiment was conducted at the Field Experimentation and Farm Research Centre Department of Genetics and Plant Breeding, during the Rabi season (2022-2023) at Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj (U.P.). To evaluate the “Biofortification with micronutrients on growth parameters and seed yield on linseed (Linum usitatissimum L)”. Replicated thrice the experiment was laid out in Randomized Block Design (RBD) with 12 +1 treatments viz., T0: absolute control, T1: Zinc sulphate@ 1%, T2: Zinc sulphate @ 2%, T3: Zinc sulphate @ 3%, T4: Zinc sulphate @ 4%, T5: Boran @ 1%, T6: Boran @ 2%, T7: Boran @ 3%, T8: Boran @ 4%, T9: Ferrous sulphate @ 1%, T10: Ferrous sulphate @ 2%, T11: Ferrous sulphate @ 3%, T12: Ferrous sulphate @ 4% duration for all treatment is 3 hrs. The results showed that methods of micronutrient application through seed priming along with T1: Zinc sulphate@ 1% treatment T1 proved its superiority over the rest of the treatments on growth and seed yield parameter characters. The results revealed that treatment T1: Zinc sulphate@1% for 3 hrs seed application with recorded maximum germination percentage, Plant height(cm) at 90 DAS, Days to 50 per cent flowering, Days to Maturity, and Number of capsules per plant, Number of seeds per capsules as well as noticed capsule per seed, Seed yield/plant(g), Biological yield of linseed. Further, results indicated that 1000 seed weight (g) was significantly improved with the application of treatment T1. The lowest values related to all parameters were obtained in the control plot treatment.

Conclusion

Seed biofortification like Boron (B), iron (Fe) and zinc (Zn) for the enhancement of linseed yield along with the distribution of different plant parts. Quantitative enhancement in different traits of linseed plants due to B, Fe and Zn fertilization especially for capsules per plant after maturity suggested a positive association between nutrient supply and morphological traits, which indirectly enhanced seed yield. There was a positive correlation between Zn supply and seed yield. In the treatments with B and Fe fertilization, seed yield was positively correlated to plant height, capsules per plant and seeds per five capsules. According to this study, it is concluded that linseed can accumulate majorly Zn followed by Fe and B. The results revealed that treatment T1: Zinc sulphate @ 1% for 12 hrs seed application with recorded maximum Plant height (cm) at 90DAS (88.6 cm), Days to 50 % flowering (68.33 %), Days to Maturity (113.3), and Number of capsules per plant (26.40), Number of seeds per capsule (9.40) as well as capsule seed yield/plant (g) (3.98), Biological yield(g) (7.77 g) of linseed. Further, results indicated that 1000 seed weight (g) (9.30) and then followed by T3- Zinc sulphate (3%). Outlook: Zinc sulfate, boron, and iron sulfate are essential micronutrients that play crucial roles in plant growth, development, and overall yield. Each nutrient has specific functions that contribute to various physiological processes within plants. Balanced and adequate supply of these micronutrients is essential to ensure optimal plant growth, health, and yield. Deficiencies or excesses of these micronutrients can lead to various physiological disorders, impacting the overall productivity and quality of crops. Farmers often use fertilizers containing these micronutrients to supplement the soil and ensure plants have access to the necessary amounts for their growth and development.
