Abstract

Tuberose is an economically important ornamental crop valued for its fragrant flowers used in the cut flower trade and perfume industry. The present study was conducted at the Horticulture Section, College of Agriculture, Nagpur, from May 2022 to March 2023. The experiment was laid out in a factorial randomized block design with four levels of vermiwash (0, 50, 100, and 150 ml/L) and four levels of potassium nitrate (0, 1.0, 1.5, and 2.0%), replicated thrice. Foliar application of vermiwash at 150 ml/L combined with potassium nitrate at 1.5% significantly enhanced plant height, number of leaves, and leaf area at 50% flowering. This treatment also induced early spike initiation, floret opening, and flowering, and recorded the highest spike and floret yield. Floret length and diameter were also significantly improved. The combined treatment V4P3 proved most effective for improving growth, yield, and quality of tuberose cv. Prajwal
