Abstract
The experiment “Response of cucumber to foliar application of acetyl salicylic acid and different sowing dates” was conducted at Horticulture Research Farm during 2017. The experiment was performed in a Randomized Complete Block Design with split plot arrangement, replicated three times. The experiment was comprised of two factors i.e sowing dates (5th, 15th and 25th April) and acetyl salicylic acid concentrations @ 162, 216 and 270 mg L-1. The statistically analyzed data indicated that different sowing dates and acetyl salicylic acid significantly affected the growth and yield contributing attributes of cucumber. Among the different sowing dates, maximum number of fruits plant-1 (11.1), minimum male to female flower ratio (2.78)), maximum fruit length (17.01 cm), fruit diameter (4.27 cm), vine length (167 cm), yield plant-1 (1.90 kg) and total yield (42.2 tons ha-1) were observed at 5th April, but this sowing date took maximum days to first flowering (40) and days to first harvest (62). In case of Acetyl salicylic acid, minimum days to first flowering (34), days to first harvest (54), and male to female flower ratio (2.93) and maximum number of fruits plant-1 (10.9), fruit length (16.78 cm), fruit width (4.32 cm), vine length (167 cm), yield plant-1 (1.80 kg) and total yield (40.2 tons ha-1) were observed in plants treated with 270 mg L-1 acetyl salicylic acid. It was concluded that sowing at 5th April and acetyl salicylic acid @ 270 mg L-1 enhanced the growth and yield contributing attributes of cucumber in agro climatic condition of Peshawar valley.
