A field experiment was conducted at College of Horticulture, Mudigere during 2019-20. The experiment was laid out in Randomized complete block design (RCBD) with eleven treatments replicated thrice. Treatments comprised of different levels of bio-stimulants and micronutrients, sprayed at three different stages such as vegetative, flowering and fruit set. Results of the experiment revealed that, Sea Weed Extract - Biovita at 0.5 % exhibited superior performance than the other treatments with respect to morphological parameters viz., plant height (1.97 m), stem girth (6.30 cm), plant spread (1.59 m in N-S and 1.51 m in E-W), canopy volume (6.23 m3), number of new shoots per plant (44.26), length of newly emerged shoots (20.50 cm) and leaf area (11.33 cm2), followed by Citrus special at 0.5 % and the lowest was recorded with control. Flowering parameters like days taken for first flower emergence (28.67 days), days taken for 50 per cent flowering (34.00 days), number of flowers per cluster (6.03), number of flower clusters per plant (56.33), flowering intensity (33.69) were maximum with biovita at 0.5 per cent and minimum was recorded with control.
