Response of INM and plant growth retardants on flowering and yield of golden rod (Solidago canadensis L.) cv. Local

Abstract

The present experiment entitled under “Response of INM and plant growth retardants on flowering and yield parameters (Solidago canadensis L.) cv. Local” in Saurashtra region” was conducted at, Floriculture farm, Jambuvadi, College of Horticulture J.A.U., Junagadh, Gujarat, during two consecutive years 2023-24 and 2024-25. The experiment was assigned a Randomized Design with factorial concept with 18 treatment combinations arising from six levels of INM (with three replications). Results reveal While in case of flowering parameter minimum number of days for panicle iniation (72.22 days, 82.22 days and 77.22 days), maximum length of panicle (54.78 cm, 57.33 and 56.06 cm), maximum diameter of main flower stalk (6.42 mm, 6.47 mm and 6.44 mm) and maximum number of inflorescences per panicle (36.89, 36.11 and 36.50) was found in I4 treatment during both the years as well as pooled. Whereas in yield parameter number of panicles per plant (2.60, 2.59 and 2.60) and number of panicles per hectare (2.88 lakh, 2.89 lakh and 2.86 lakh) was found in I4 treatment during both the years as well as pooled.
