Abstract:
The present investigation was carried out to evaluate the effects of micronutrients (iron, zinc) and PGR on quality seed production of cucumber cv Pusa Barkha. The seed lot was undergone different seed treatment with micronutrient (FeSO₄ and ZnSO₄) solution with four concentration (100, 125 and 50, 75 ppm) for 12 hours followed by foliar spray of Ethrel with three concentrations (100, 200, 300 ppm) at 2-4 true leaf stage.Seed treatment with Fe (125 ppm) showed higher 1000 seed weight, root length, seedling dry weight, seedling vigour index-I &II. Further, treatment with Fe (100 ppm) showed higher shoot length and with Fe (125 ppm) and foliar spray of Ethrel (200 ppm) showed higher seed germination. The foliar spray with Ethrel (200 ppm) resulted in lowest electrical conductivity and highest dehydrogenase activity as compared to control. Seed treatment with micronutrients Fe (100,125 ppm) and Zn (50, 75 ppm) improved seed quality parameters but Fe (125 ppm) was more effective.
