A COMPARATIVE STUDY ON IMPACTS OF WATER STRESS INTURMERIC VARIETIES ACC 48 AND ACC 79S. Kedarini and Singisala Nageswara RaoAbstract Water stress created in turmeric varieties Acc 48 and Acc 79 by irrigating them in different intervals. Waterstress influence on morpho-logical features, physio-logical and yield features of both the varieties wasinvestigated. In this study irrigation treatments divided into three groups. Group A control receives waterweekly once. For every two weeks once group B was irrigated and for every three weeks once group C wasirrigated. Plants which are under heavy water stress showed gradual reduction in morphological,physiological and in yield parameters, i.e. âplant height, number of leaves, width of the leaf, fresh and dryweight of rhizome, Relative Growth Rate, Net Assimilation Rateâ. Acc 48 & Acc 79 morphological- parameters,physiological and yield parameters was slightly affected in moderate stress compared to control. Amongthe two Acc 48 resisted water stress in moderate stress condition than Acc 79. In heavy water stress condition,the two varieties severely affected compared to control and moderate stress. Among the two varieties Acc48 was less affected. In all the treatments Acc 48 was less affected in all aspects except in thin and tuberousroots number. To cope up with water stress length of thin and tuberous roots of both the varieties wereincreased in heavy and moderate water stress condition. Irrigating turmeric two weeks once showed minorimpact on plants than irrigating them three weeks once. In heavy water stress, plants was affected in allmorphological, physiological and yield aspects. |
