Exploring Polybag Size, Nursery Mixtures and Rootstocks for Optimizing Lasoda (Cordia myxa L.) Nursery Techniques

Background: Lasoda (Cordia myxa L.) is lesser utilized fruit plant species suitable for growing in large parts of arid and semi-arid regions of India. Besides the economic importance of its fruits in the vegetable and pickle industry, this species is also known for ethnomedicinal properties in different plant parts. In order to utilize it to its fullest potential, standardization of nursery technology for mass multiplication by vegetative propagation method is a necessary step. With the above background in the view, an experiment was conducted to see the effect of polybag size, nursery mixture and rootstock on seed germination, growth of seedlings after germination, budding success and growth of budded plants. Methods: The study was conducted during June-September, 2020. The treatment comprised of two polybag sizes, six nursery media compositions and two kinds of rootstocks. The observations were recorded on seed germination, seedling growth, days to bud sprout after budding, budding success and shoot length and diameter after 30 days of budding. Result: The main effects of nursery mixture revealed that plant height, stem diameter, number of leaves, shoot length and shoot diameter after budding were significantly affected by nursery mixture composition. The highest plant height (29.53 cm) recorded in the M4 mixture was significantly higher over M1, M2 and M3 but the differences were non-significant when compared with M5 and M6. A similar trend was also recorded in the case of stem diameter and number of leaves which showed significantly higher values in M4, M5 and M6 as compared to M1, M2 and M3. The highest shoot length (8.34 cm) and shoot diameter (3.40 mm) were recorded in M5 and M4 which were significantly higher than most of other media levels.
