Background: As a result of its influence on nurses’ knowledge and practice, evidence-based practice (EBP) has gained prominence in the nursing profession. Therefore, evidence-based practice (EBP) is increasingly acknowledged as a critical component of improving the quality of healthcare and nursing care services, as well as achieving patient care excellence. Aim: One of the primary objectives of this review is to consolidate the existing research on nurses’ understanding of evidence-based practice, attitudes toward it, and practices related to it. Methods: The following databases from 2012 to 2021 have been searched such as: Cochrane Collaboration, MEDLINE, AVOID, CINAHL, EMBASE, Science Direct, ASSIA, Web of Science, Scopus, PubMed and JSTOR. Only cohort, case-control and randomized controlled trials studies with full text in English were eligible. Results: Only eight articles were found to meet the inclusion criteria out of 2155 total articles after the exclusion criteria were applied. The majority of these eight researches discovered a favourable attitude about EBP as well as a low level of expertise. Conclusion: The majority of nurses have a good attitude toward their job, but most are uninformed of the significance of EBP in their profession. In order to recognize and compare the components that may impact knowledge, attitude, and practices of EBP throughout the world in order to discover similarities that may assist global strategies for the transfer of research results to nursing, additional research on this topic is required to recognize and compare the components that may impact knowledge, attitude, and practices of EBP throughout the world in order to discover similarities that may assist global strategies for the transfer of research results to nursing.

In total 36 superior clones of Dalbergia sissoo Roxb., screened from 300 selections conducted in natural and growing range of India and Nepal, were multiplied using single nodal cuttings and estab- lished to evaluate genotypexenvironmental interactions for adaptability and stability at the age of 30 months in three geographical locations in the state of Punjab, India. Clone 124 had maximum adaptability and stability （bi = 1.04） to perform exceedingly well over the locations. Clones 36 and 1 were stable with mean regression coefficient of 0.84 and 1.22, respectively. Nonetheless, clone 4 1 performed exceedingly well for all the characters to attain maximum population mean, and the perform- ance varied substantially across the locations. Therefore, clone 41 was considered as productive but non-adaptive clone. Though some of the clones were sensitive to sites, 14 clones for height, 16 for collar diameter, 12 for DBH and 7 for volume were relatively un-sensitive with higher regression coefficient. Nonetheless, clone 124 was the most Stable with average bi value of 1.04 and productive, which could play an important role in future breeding and commercial deployment of stable and produc- tive planting stock of Dalbergia sissoo.
