Effect of levels of fertigation and foliar spray of micronutrients on growth, flower quality and flower yield in G.I tagged Jasminum sambac cv. “Mysuru Mallige”

Abstract

An experiment was conducted to known the fertigation levels along with foliar spray of micronutrients on Jasminum sambac cv. Mysuru Mallige in the farmer field near College of Horticulture, Mysuru during 2017-2018. The experiment was laid out in RCBD design with 9 treatments and 3 replications. The plant nourished with 100 per cent recommended dose of fertilizer along with foliar spray of micronutrients resulted in increased plant height (53.30, 60.75, 66.58, 72.70, 76.33 and 80.73 cm at 30, 60, 90, 120, 150 and 180 days after planting respectively), Highest individual leaf area and chlorophyll content of the leaf (28.50 cm2 and 57.45 SCMR value), Maximum flowers bud diameter (3.13 cm) bud length (1.62 cm) corolla length (1.16 cm), flower diameter (4.39 cm), Highest score for freshness (4.91), fragrance (4.91), minimum loses of physiological weight (8.50 %) more shelf life of the flowers (34.10 hours) and flower yield (725.80 g/ plant) was also recorded.
