Role of Elicitors on Growth Attributes of Sacred Basil (Ocimum sanctum L.)

Abstract

The present experiment was conducted during 2021 and 2022 at College of Horticulture, SKLTGHU, Rajendranagar. The experiment was laid out in a factorial randomized block design (RBD) comprising 14 treatments with three replications. The results conferred that during both the years and pooled, the growth parameters viz., maximum plant height (cm) (123.60, 123.28 and 123.44), number of primary branches per plant (49.10, 48.88 and 48.99), number of secondary branches per plant (117.87, 115.59 and 116.73), and plant spread (E-W) (cm) (71.39, 72.34 and 71.87) were recorded in T5 (V1E5) - CIM- Ayu + Salicylic acid @ 0.5 mM, Whereas maximum plant spread (N-S) (cm) (71.19, 73.30 and 72.25) was recorded in T5 (V1E5) - CIM- Ayu + Salicylic acid @ 0.5 mM which was at par with T12 (V2E5) - CIM- Angana + Salicylic acid @ 0.5 mM (70.33, 72.44 and 71.38) respectively at 75 DAT. The treatment T5 (V1E5) - CIM- Ayu + Salicylic acid @ 0.5 mM recorded maximum leaf area (cm2/plant) (6481.40, 6925.57 and 6703.49), leaf area index (4.05, 4.33 and 4.19), fresh weight of plant (g/plant) (695.25, 697.25 and 696.25) and dry weight of plant (g/plant) (224.67, 234.97 and 229.82) during both the years and pooled, respectively. There was no significant difference observed among the interaction effects with respect to harvest index during both years.
