Evaluation on Performance and Superiority of Tuberose (Polianthes tuberosa L.) Cultivars for Growth and Flowering under North Indian Plain

摘要

A field experiment was carried out to evaluate tuberose (Polianthes tuberosa L.) cultivars for growth and flowering under north Indian plain. The experiment was laid out in randomized block design comprising thirteen cultivars viz. Local, Mexican Single, Hyderabad Double, Sikkim Selection, Phule Rajani Single, Phule Rajani Double, Suvasani, Prajwal, Shringar, Pearl Double, Hyderabad Single, Calcutta Double and Vaibhav as treatment with three replications. The crop was planted on 6th May 2014 following standard cultivation practices. The experimental result showed that there was significant difference among cultivars for differtent characters studied. Days to sprouting was recorded minimum in cv Local (5.00 days). Length of leaves was recorded maximum in cv Prajwal (38.81 cm). Maximum plant spread was recorded in cv Suvasani (45.06 cm). Maximum dry weight was attained by cv Calcutta Double (2.84 g) followed by cv Prajwal (2.78 g) which were at par. Maximum dry matter of leaves was attained by cv Calcutta Double (14.30%) and minimum in cv Local (11.51%). Minimum days to spike emergence was recorded in cv Local (57.88 days) followed by cv Suvasani (63.66days) which were at par. Minimum days to full bloom was recorded in cv Local (95.66 days) follolowed cv Shringar (100.33 days). Flower life in field was recorded maximum in cv Suvasani (23.66 days) followed by cv Pearl Double (22.22 days) which were at par. Maximum length of spike was recorded in cv Sikkim Selection (101.56 cm). Maximum number of florets per spike was recorded in cv Pearl Double (43.43) followed by cv Phule Rajani Single (42.10) which were at par. From these findings we can conclude that cv Prajwal, cv Suvasani and cv Local can be recommended for commercial cultivation in northern plain of India under Varanasi Agro-climatic zone.
