Iris laevigata Fisch., is restricted geographically in Manipur, north eastern India. An experiment was planned with Factorial Randomized Block Design during 2018 to 2020 (3 seasons) in the study plots of ICAR Research Complex for NEH Region, Manipur Centre, Lamphelpat. The study encompasses on the growth and development of I. laevigata seedlings collected from Ipa Thoukok Complex: influenced by spacing, trimming and correlations amongst the growth parameters, so as to validate the most favourable conservation method for this endangered plant. Among the treatments, T6 = S2T3 (45 cm × trimming 40 DAT) was found the best treatment. T9 = S3T3 (60 cm × trimming 40 DAT) was second, T3 = S1T3 (30 cm × trimming 40 DAT) was the third and lowest was found in case of T1 = S1T1 (30 cm × 0 trimming, i.e., without trimming). Strong positive correlation between leaf surface area and plant height on the growth and development was found to be effective among other correlations.
