Effect of Different Bio-stimulantss on Growth, Flowering, Yield and Post-harvest Quality of Dahlia (Dahlia Variabilis L.) Under Western Uttar Pradesh Conditions

Abstract

The present investigation was conducted to assess the “Effect of different biostimulants on growth, flowering, yield, and post-harvest quality of Dahlia (Dahlia variabilis L.) under western Uttar Pradesh conditions”, at Horticultural Research Centre (HRC) of Sardar Vallabhbhai Patel University of Agriculture and Technology, Modipuram, Meerut – 250110. Among the treatments applied in the study, maximum plant height, plant spread, leaf width, number of branches/plant, days to first flower opening, days to 50% flowering, number of flowers per plant, stalk length (cm), yield of flower per plant in (g), yield of flowers per plot (kg) yield of flowers per hectare (tonnes), and longevity of flowers were recorded with the application of treatment T9 (50% RDF+ 5% Sea weed extract + 3% Humic Acid + 3% Panchgavya foliar spray) whereas the application of T3 (25% RDF+ 7% Panchgavya foliar spray) was least effective in improving the growth, and yield of dahlia whereas, the most effective treatment in enhancing the tuber quality and produce was (75% RDF + 3% Humic Acid foliar spray) which also was most effective in inducing earliest flowering. Based on the results obtained from the present study, it may be concluded that, among all the treatments of biostimulants, application of T9 (75% recommended dose of 50% RDF+ 5% Sea weed extract + 3% Humic Acid + 3% Panchgavya foliar spray) was found to be most effective in improving the growth and flower yield of Dahlia whereas, the most effective treatment for tuber yield and quality was 75% RDF + 3% Humic Acid (foliar spray) under the climatic conditions of Western Uttar Pradesh
