Abstract:
The present investigation entitled ‘Response of Bio-enhancers on Growth and yield of Marigold (Tagetes erecta L.) cv. Punjab Gainda No.1 was carried out during winter season of 2020-21 at IFTM University, Moradabad. (U.P.) The experiment was laid out in Randomized Block Design along with three replications and eight different treatment combinations of Bio-enhancers viz. (T₁) Panchagavya 4%, (T₂) Jivamrita 30%, (T₃) Vermiwash 10% (T₄) Panchagavya 4% +Jivamrita 30%, (T₅) Panchagavya 4% + Vermiwash 10%, (T₆) Jivamrita 30%+Vermiwash 10%, (T₇) RDF: (90:90:75:N:P:K), (T₈) control. Amongst all treatment combination, T₅ (Panchagavya 4% + Vermiwash 10%) was found with the higher values of different vegetative growth and yield parameters, such as Plant height (31.47cm), Number of primary branches (8.27) and Secondary branches (25.67), Plant spread (18.63cm), Days to first flower bud initiation (27.60), Days of first flower bud opening (41.80), as well as flower yield parameters like Number of flowers (46.33), Flower yield (25.33). Thus, use of bio-enhancers resulted in excellent vegetative growth and flower yield attributes in African marigold Cv. Punjab Gainda No.1.
