Abstract
Abstract The experiment was conducted at New Horticulture Research Farm Malakandher, The University of Agriculture, Peshawar, Pakistan during the year 2016. The experiment was laid out according to Randomized Complete Block Design (RCBD) with 2 factor factorial, having 24 treatments each replicated three times. Factor (A) consisted of okra cultivars (Punjab Selection, Sabz Pari, Supper Green and Swat Green). Factor (B) consisted of different single super phosphate concentrations {0.5%, 1%, 1.5% and 2%}.Seeds were primed for 24 hours. Unprimed seed and priming with water were taken as control treatments. Results showed that seed primed with 0.5 % of single super phosphate concentration had maximum germination percentage (93.17 %), minimum number of days to emergence (5.12 days) and number of days to first flowering (29.77 days), maximum plant height (140.84 cm), number of leaves plant-1 (32.62), number of pods plant-1 (25.09), pod length (9.76 cm), number of seeds pod-1 (42.22), pod yield (8.94 tons ha-1), seed yield (769.98 kg ha-1), and 100 seed weight (6.34 g), whereas maximum survival percentage (95.55 %) was recorded in the seeds primed with 2% SSP. In case of cultivars maximum germination percentage (88.32 %), minimum number of days to emergence (5.39 days) number of days to first flowering (30.67 days) maximum plant height (140.11 cm), number of leaves plant-1 (31.59), number of pod plant-1 ( 24.22), pod length (9.37 cm), number of seeds pod-1 (41.39), and pod yield (8.84 tons ha-1) were recorded in Sabz Pari whereas maximum survival percentage (92.72%), seed yield (768.06 kg ha-1), 100 seed weight (6.32 g) were recorded in Swat Green. It is concluded that seed priming with 0.5 % phosphorus gave better result in almost all parameters. Okra cultivar, Sabz Pari showed best result in majority attributes under the agro-climatic condition of Peshawar, Khyber Pakhtunkhwa-Pakistan.

Highlights
O Randomized Complete Block Design (RCBD) with 2 factor factorial, having 24 treatments each replicated three times
Mean table showed that priming of okra cultivars with different single super phosphate concentrations had significantly influenced number of pods per plant, while nonsignificant interactions were found among the two factors.The experimental findings revealed that maximum number of pods plant-1 (25.09) was recorded by the seed primed in 0.5% P solution of single super phosphate, while the minimum pods plant-1 (20.03) was noted in the unprimed seeds
Seed priming with super phosphate (SSP) solution gave maximum germination percentage and produced more yield than control seeds
Summary
The experiment was conducted at New Developmental Horticulture Research Farm Malakandher, The University of Agriculture, Peshawar, Pakistan during the year 2016. Soil Analysis Random soil samples from various parts of the field before sowing, up to depth of 25 cm was taken with the help of gauge auger (30 mm diameter) and analysis was carried out in the Soil and Environmental Science (SES) Laboratory at The University of Agriculture, Peshawar (Table 1). Experimental design The experiment was comprised of two factors (Table 2) and carried out in (RCBD) two factor factorial having twenty four treatments and each was replicated three times. Total experimental area was 150 m2 in which 130 m2 was crop area and the remaining was used for pathways and water channels.
