Abstract
The present investigation entitled “Evaluation of growth performance of woody perennial saplings raised in organic wastes” was carried out at Landscape nursery, Department of Floriculture and Landscaping, Punjab Agricultural University, Ludhiana during year 2021-22 with an objective to evaluate the growth performance of tree and shrub saplings in different organic wastes and standardize the organic waste-based growing media for raising healthy and disease-free saplings. Five different tree and shrub species were planted in six different organic waste-based growing media. The xperiment was laid out in completely randomized design and the data for different growth attributes were statistically analysed. The seedling and root growth parameters were found maximum in T5 i.e., press mud media. Among the trees, the highest seedlings were observed in P. roxburghii (31.27 cm) while among shrubs in L. indica (32.19 cm) and L. camara (22.24 cm). The root collar diameter among trees was found maximum in P. roxburghii (4.53 mm) while among shrubs in L. camara (4.07 mm) and L. indica (5.37 mm). However, most number of primary branches per plant in terms of tree species was recorded in K. paniculata (2.77) and among shrubs in T. divaricata (4.52) and L. indica (3.31). The shoot dry weight for both trees and shrub species was also found to be maximum in pressmud media which was highest in P. roxburghii (4.26 g) among trees and L. camara (4.09 g) and L. indica (4.89 g) among shrub species. The survival percentage among different treatments was found to be maximum in B. variegata (94.81%) among trees and among shrubs in T. divaricata (94.07%) and T. peruviana (93.33%) grown in press mud media (T5). As for root growth characteristics, the primary root length was found maximum in K. paniculata (26.62 cm) among trees while in shrub species in L. camara (23.20 cm) and T. peruviana (21.56 cm). The primary root diameter was found to be best in P. roxburghii (3.57 mm) among trees while in shrub species in L. camara (3.29 mm) and T. peruviana (3.66 mm). While root dry weight among tress species was found to be maximum in K. paniculata (4.95 g) whereas among shrub species B. sempervensis (3.64g) and T. peruviana (3.30 g) grown in press mud media (T5). The chemical and physical properties were also found to be best in press mud based treatment T5. Based on the study, it can be concluded that the press mud based organic waste media can be used for raising the trees and shrubs nursery successfully.
