Evaluation of Primed Coriander Seeds for Phenological, Yield Attributing and Physiological Characteristics

This study was conducted over two consecutive years (2021-22 and 2022-23) at Research field, Dept. of Seed Science and Technology, Chauras Campus, H.N.B. Garhwal Central University, Uttarakhand, to assess the impact of various seed priming treatments on coriander's phenological, yield attributing and physiological characteristics. The experiment included priming treatments with Trichoderma viride, vermiwash, silver nanoparticles, concentrated H₂SO₄, and plasma, with unprimed seeds as controls. The germplasm was procured from the bhatwari village of Uttarakashi District in Uttarakhand. Field trials demonstrated that silver nanoparticle priming significantly enhanced plant height, early flowering, umbel production, and seed yield. Physiological analysis revealed increased chlorophyll and protein content in primed seeds, indicating improved seed quality. These results suggest that silver nanoparticle priming is the most effective method for enhancing seed performance and yield potential in coriander. This study underscores the significance of advanced priming techniques in sustainable seed enhancement and productivity under diverse environmental conditions.
