Influence of biostimulants on growth and yield of floribunda rose cv. Mirabel

Abstract

The present investigation was undertaken to study the effect of biostimulants on growth and yield of Floribunda rose cv. Mirabel. The biostimulants viz., Panchagavya, Jeevamrutha, Amruthpani, Cowurine, Humic acid and Biovita were sprayed at different concentration at monthly intervals (30, 60, 90, 120, 150 and 180 Days after planting respectively). Among different biostimulants, foliar application of T14 (50% RDF + Panchagavya @ 2% + Jeevamrutha @ 400 liter /ha + Humic acid @ 2% + Biovita @ 2% + Cowurine @ 20%) recorded significantly maximum plant height (82.25 cm), number of primary branches (6.03), number of secondary branches (22), plant spread in East-West direction (81.45 cm), plant spread in North-South direction (82.44 cm) stem girth (19.77 mm), leaf area (839.37 cm2) number of flowers per plant (58.60) and cumulative flower yield per plant (427.44 g) at 180 DAP as compared to control. This study indicated that foliar application of T14 exhibited superior for growth and yield parameters of Floribunda cv. Mirabel.
