A study was undertaken at the Botanical Garden, TNAU Coimbatore during the year 2009–10 to study the influence of precision technologies on growth and yield of Jasminum sambac cv. Ramanathapuram Gundumalli. The crop was grown under precision method of cultivation and this was compared with conventional method of cultivation (control). Observations were recorded on the growth parameters and flowering parameters during peak flowering stage and yield of flower buds throughout year. The results indicated that drip fertigation with 125% recommended dose of fertilizer in combination with foliar spray of humic acid (0.4%) and panchagavya (3%) recorded the highest plant height, plant spread, dry matter production, minimum number of days taken for first flower bud emergence, highest number of cymes plant-1, bud length, bud diameter and yield of flower buds. This was closely followed by the treatment with 100% recommended dose of fertilizer in combination with humic acid (0.4%) and panchagavya (3%) spray. However, this treatment showed its superiority by registering highest BCR over other treatments.
