Field experiment was conducted to study the effect of harvesting stages i.e. (mature pod of turning stage, brown undried stage and brown dried stage) on seed yield and quality attributes of okra sown at different dates (March 10, March 30, April 19 and May 9) at Agriculture Research Institute Tarnab Peshawar, during 2016 and 2017. A Randomized Complete Block Design (RCBD) with split plot arrangement having sowing dates as the main plot factor, while harvesting stages as sub plot factor was used. The average of two years results showed that maximum number of seeds pod-1 (58.09), seed weight pod-1 (3.57g), 1000 seed weight (g), seed yield (1.72t ha-1), germination (79%) and seedling vigor index (2114.16) was observed in plants sown on March 30 as compared to late sown plants on May 9. As for as harvesting stages are concerned, maximum seed weight pod-1 (3.57g), 1000 seed weight (61.33g), seed yield (1.67t ha-1), germination (80.73%), and seedling vigor index (2181.73) was recorded when seeds were harvested at brown dried stage. The D x H interaction significantly influenced seed weight pod-1, germination and seedling vigor index.
