Abstract

  Marigold (Tagetes patula) is one of the popular annual, herbaceous, attractive flowers. Salicylic acid (SA) is a phenolic phytohormone and is found in plants with roles in plant growth and development, photosynthesis, transpiration, ion uptake and transport. This research was conducted to assess the effects of foliar application of salicylic acid on growth and yield of marigold from July 2019 to November 2019. The research was conducted in the horticulture field of IAAS, Lamjung Campus, Nepal under Randomized Complete Block Design with three replications and six treatments viz. (0, 100, 200, 300, 400, 500) ppm of salicylic acid. The marigold flowers were harvested when the outer petals unfold nearly perpendicular to the stem. Parameters like plant height, plant width, days to flowering, number of flower diameter and total yield were observed and analyzed using SPSS. Greater plant height was found on treatment 500 ppm which is statistically on par with 400 ppm and 300 ppm and lowest at 0 ppm. Similarly, plant width is grater in 500 ppm while the lowest in 0ppm. Days to flowering were lower in 500 ppm which is statistically similar with 400 ppm, 300 ppm and 200 ppm and higher in 0 ppm. Best results were found in 500 ppm with the number of flowers, the diameter of the flower, and flower yield. Thus, results revealed that increasing the concentration of salicylic acid increases the production of marigold.
