Abstract

An experiment was conducted in Research Field, Department of Horticulture, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj, during November, 2020 to March, 2021 to find out effect of pinching and Organic manures on growth, flowering and yield of Dahlia (Dahlia variabilis L.) cv. Red symphony. The seedlings were planted at a spacing of 60 cm × 80 cm from row to row and plant to plant to accommodate six plants per 1.8 meter square area. The experiment was laid out with thirteen treatments replicated thrice in Randomized Block Design. Based on the present investigation it is concluded that the treatment T10 Pinching 40 DAT + Poultry manure (3t/ha) followed byT6 Pinching 40 DAT + Vermicompost (5t/ha) and T2 Pinching 40 DAT + FYM (10t/ha). Found best in terms of plant growth parameters, flower and yield and tuber yield of Dahlia. However, while the experiment was conducted, it was observed that flower size reduced and failed to attain an expected large bloom
