Abstract

The present study has been conducted to study the effect of various primer treatments i.e., PEG (5%), PEG (10%), NaCl (2%), KCl (2%), CuSO4•5H2O (2%), NaOH (2%) and control on germination and growth of two okra (Abelmoschus esculentus) varieties (var. Arka Anamika and Clemson). Growth parameters were measured at 10, 20, and 30 DAS, while germination parameters were recorded over a period of seven days. Compared to Arka Anamika, Clemson showed better germination and growth metrics, which also showed significant differences in seed priming treatments. The use of different concentrations of PEG solution for seed priming proved to be particularly effective as evidenced by the highest germination percentage (79%), speed (95.95%), energy (76%), and Vigor index (2037.94 cm). Growth parameters also showed significant differences with these treatments. Similarly, seed priming with 2% NaOH and 2% CuSO4•5H2O had the lowest results for growth and germination metrics. The results highlight how priming can significantly improve the germination and growth of okra seedlings; the Clemson and PEG solution treatments stand out as particularly successful techniques. This highlights the potential for improved okra production through the use of these priming methods.
