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.
