Year: 2019
Type: article
Abstract: The present investigation was carried out in the Department of Horticulture, Faculty of Agriculture, Annamalai University, Annamalai nagar during 2013-2015 in Randomized Block Design with eleven treatments and three replications.The eleven treatment combinations were formed by foliar application of zinc and boron viz., Zinc sulphate (0.25, 0.50 and 0.75%) and Borax (0.25, 0.50 and 0.75%) on 30, 60 and 90 DAP, individually and incombination with 25 tha -1 FYM and recommended dose of 200:200:200 kg ha -1 NPK.The control was maintained with water spray.Various biometric observations on growth, yield and quality of tuberose were observed for all the treatments.Among the treatments, the biometric observations like plant height (47.25 cm), number of side shoots per plant (8.89), number of leaves per plant (36.19), plant spread (24.50 cm 2 ), leaf area (42.50 cm 2 ), chlorophyll content (0.918 mgg -1 ) and dry matter production (23.15 g plant -1 ) and yield attributes, viz., days to fifty per cent flowering (90.47 days), number of spikes per plant (4.55), spike length (95.42 cm), rachis length (28.89 cm), number of flowers per spike (41.52), flower length (6.66 cm), flower diameter (4.03 cm), hundred flowers weight (94.73 g), flower yield per plant (128.65 g plant -1 ), flower yield per plot (1.54 kg plot -1 ), flower yield per hectare (14.28tha -1 ), number of bulbs and bulblets (18.23) and weight of bulbs and bulblets (236.52 g plant -1 ) and the quality characters such as shelf life (12.76days) and visual scoring (9.10) were recorded the maximum with the treatment combination of T 10 (25t ha -1 FYM+Recommended dose of 200:200:200 kg ha -1 NPK+Zinc [email protected]%[email protected]%on 30, 60 and 90 DAP), followed by T 9 .
