Abstract

Plant-derived bio-stimulants such as Moringa leaves extract are known for increasing the growth and yield of horticultural produce besides having no toxic effects as compared to synthetic fertilizers. Keeping in view its importance a field experiment entitled “Exogenous application of Moringa leaves extract influences growth, flowering and vase life of snapdragon cultivars” was carried out at Malakander Horticulture Research Farm, University of Agriculture Peshawar, Pakistan during winter, 2019. The experiment was laid out in Randomized Complete Block Design with a factorial arrangement having two factors i.e. Cultivars (Potomac and Rocket) and Moringa leaf Extract (MLE) concentrations (0%, 10%, 20%, 30%) replicated three times. Cultivars and MLE concentrations significantly affected the studied parameters. Statistical analysis showed that Rocket cultivar produced maximum numbers of leaves plant-1 (126.50), stem diameter (11mm), plant height (100cm), number of florets spike-1 (34), flowering duration (39days) and vase life (6days) as compared to Potomac cultivar. Similarly, most number of leaves plant-1 (114), stem diameter (11mm), plant height (99cm), number of florets spike-1 (35), flowering duration (44 days), and vase life (8days) was recorded in plants treated with 30% MLE extract. It is concluded that 30% MLE for exogenous application and Rocket cultivar for commercial production is recommended in agro-climatic conditions of Peshawar valley.
