Abstract

This research was conducted to overcome the problem of slow and erratic emergence in okra and to find out the effect of plant extracts on germination, growth and yield in okra at Research Field of Lovely Professional University (LPU), Phagwara, Punjab, India (March-June, 2022). Punjab Suhawani variety was used for experiment. The experiment was laid out in Randomized Block Design (RBD) with 8 treatments and 3 replications, i.e. T1 (Amla leaf extract@ 3%), T2 (Tulsi leaf extract@ 3%), T3 (Reetha leaf extract@ 3%), T4 (Bael leaf extract@ 3%), T5 (Arjuna leaf extract@ 3%), T6 (Neem leaf extract@ 3%), T7 (Baheda leaf extract@ 3%) and T0 (Control). Field experiment results showed that seed treatments with different plant botanicals proved effective in improving germination percent, improving the growth parameters (seedling shoot length, seedling root length, seedling length, fresh weight of seedlings, dry weight of seedlings, seedling vigour index-I, seedling vigour index-II, plant height, number of leaves and yield contributing characters like number of pods per plant, length of pods, width of pods, individual pod weight, pod yield per plant (g), pod yield (kg/plot) and pod yield (tonnes/ha) as compared to control (un-treated seeds). The highest and lowest germination percentages were found in T5 (Arjuna leaf extract@ 3%) and T0 (Control) respectively while better growth performance in T5 (Arjuna leaf extract@ 3%) and T7 (Baheda leaf extract@ 3%). Similarly, T5 (Arjuna leaf extract@ 3%) and T7 (Baheda leaf extract@ 3%) resulted in higher yield. Hence, it is suggested that seed treatments with different plant botanicals is important to improve the overall germination, growth performance and yield in okra.
