Influence of spacing and fertilizer levels on growth, flowering, yield and quality of crape jasmine (Tabernaemontana divaricata (L.) R. Br. ex Roem. & Schult.)

A field experiment was conducted during the year of 2023-24 at the Floriculture block, MHREC (Main Horticultural research and extension center), College of Horticulture, University of Horticultural Sciences, Bagalkot. The experiment was laid out in a factorial RCBD with three replications, comprising three levels of fertilizer and three different spacings, resulting in 09 treatment combinations. The highest fertilizer level F₃, recorded maximum growth, flowering, yield and quality parameters. Among various spacing levels, the maximum growth, flowering, yield and quality parameters were observed at optimum spacing S₂, with the exception of plant height (137.41 cm), internodal length (5.19 cm), which were reported at closer spacing S₁. In terms of different treatment combinations, the growth, flowering, yield and quality attributes were maximum in the treatment combination of S₂F₃, except for plant height (140.35 cm), internodal length (5.50 cm), which was recorded in the S₁F₃ treatment combination.
