Abstract:
A study of the effect of bio-regulators along with organics on growth and yield of Gundumalli (
Jasminum sambac Ait) was conducted. The organic manures viz., Farmyard manure, Vermicompost along with bio regulators like Naphthalene acidic acid, Gibberellic acid and panchagavya was given as foliar application. Among the various treatments application of vermicompost @ 2.5 t ha
-1 along with foliar spray of panchagavya @ 3 percent was significantly increasing the plant growth characters of plant height (124.52 cm), Number of primary shoots (10.71), Number of secondary shoots (10.41), Number of leaves (260), leaf area (27.56 cm
2), Number of productive shoots (55.47) and chlorophyll content (2.64 CCI). Flowering parameters viz, commencement of flowering (50.97 days), length of flower bud (3.66 cm), flower bud diameter (3.58 cm), bud length without corolla (1.89 cm), Corolla tube length (1.63 cm), and flower yield characteristics viz, hundred bud weight (26.39 g), flower yield per plant (677.74 g), flower yield per plot (4066.44 g), flower yield per hectare (3.78 t/ha), and the quality characters like shelf life (34.39 hrs) was achieved in Gundumalli (
Jasminum sambac Ait). From the experiment application of treatment combination of vermicompost @ 2.5 t ha
-1 along with foliar spray panchagavya 3 percent, could adjudged as the best treatment in performance of Gundumalli under the open field condition.
