Abstract
The present investigation was carried to study the efficacy of nutrients and biostimulants on flowering and yield attributes in tuberose cv. Bidhan Rajini-1. The experiment consisted of four biostimulants viz., Humic acid, Fulvic acid, Potassium humate, Arka Microbial Consortium in combination with nutrients. Further regarding the flower yield contributing parameters, the application of 75% RDF along with Humic acid-12% (3ml/l) resulted in maximum number of spikes per clump (3.30), number of florets per spike (66.0), weight of individual florets (2.56gm) and 100 flowers weight (256.6gm), loose flower yield plot-1 (17.67kgs) and flower yield ha-1(44 t) followed by 100% RDF (200kg each of NPK).
