Abstract: An experiment was conducted to determine the effect of seed priming on the germination and seedling growth of cardamom. The experiment consisted of two factors, namely; five priming solutions (distilled water, KNO3 (0.2%), GA3 (200 ppm), cow urine (10%), and tap water), and two soaking durations (6 hrs. and 9 hrs.). The factorial combination of these factors was arranged in a randomized complete block design and replicated four times. Different parameters were measured, including seed germination percentage, germination index, shoot and root length, fresh and dry weight of shoots and roots, as well as root volume. Notably, the main effect of the priming solution had a significant (P<0.05) effect on the aforesaid germination and seedling growth attributes. However, the main effect of soaking duration and their interaction with priming solutions did not exhibit a significant effect (P>0.05). Among the priming solutions, the application of cow urine at a 10% concentration exhibited a significant effect on the seed germination and subsequent growth of the cardamom seedlings. Advantageous results of seedling vigor indexes I and II were observed from cardamom seeds primed with the same solution. Accordingly, the growers and seedling producers in the study area are advised to apply a 10% cow urine priming solution before sowing cardamom seeds for enhanced germination and seedling growth.

Abstract: Knowledge of genetic variability is necessary to develop a suitable breeding method for crop improvement. Thus, further information on the existence of variability in sesame accessions is needed to set appropriate breeding strategies and improve sesame in terms of yield and desired quality traits. Based on this concern, this research was conducted to estimate the phenotypic and genotypic variability, heritability, and genetic advance among sesame accessions. A total of sixty-four sesame (Sesamum indicum L.) Accessions were evaluated in an 8*8 lattice design with two replications in 2021 at the Werer Agricultural Research Center. The results of the analysis of variance showed that, except for the 50% days to emergence and the number of seeds per pod, there were statistically significant differences between the accessions for all traits. A relatively high (>20%) phenotypic and genotypic coefficient of variation was estimated for the number of pods per plant, number of secondary branches per plant, seed yield, and biomass yield. High heritability coupled with high genetic advance as a percentage of the mean (GAM) was recorded for thousand seed weight, number of primary branches per plant, number of pods per plant, biomass yield, and seed yield. The information and genetic variability obtained in the present study could be used to plant appropriate breeding procedures and develop genotypes with high productivity in future sesame improvement programs.
