A field study was conducted at Debre Zeit Agricultural Research center station under rain fed condition with the objectives to determine the effect of seed priming for improving chickpea variety productivity and to determine the effectiveness of seed priming treatment and variety on stand establishment. The experimental factors were laid out in RCBD with three replications. The study indicated that all the phenological and growth traits significantly differed as a result of priming treatment and variety. With respect to yield and yield related traits, only seed yield kgha -1 , harvest index (%), seeds plant -1 and seeds pod -1 were significantly affected by the main effect. While, the rest of yield related traits responded differently due to variety alone. However, all variables studied in the field were not significantly affected by the interactions of the main effects. Improvement made due to main effect hydro and osmopriming was statistically similar for all phenological traits; seeds plant -1 and seeds pod -1 was considerably improved as a result of osmopriming than hydropriming. However, plant height, stand count at emergence and at harvest, seed yield kg ha -1 were substantially increased by 7, 10, 12 and 15%, respectively as a result of water priming over the control. Therefore, from present study, it can be concluded that hydropriming can step-up economical benefit of chickpea growing farmers.
The experiment was conducted in September 2016 at Ethiopian Biodiversity Institute genebank, germination laboratory, Ethiopia to investigate the effect of temperature on the three accessions of sesame indicum L. viz., 9015, 9026 and 241335 and (25 o c, 30 o c, 35 o c, 40 o c) were used as the constant temperature gradient. The experiment was comprised of two factors, accession and temperature. And it was designed in factorial CRD with four replications. Analysis of variance showed that the main effects and the interaction effect were highly significant (P<0.001) for standard germination percentage. The result showed that, the highest germination (94%) was recorded at a temperature of 35 o c though it was at par with the germination percentage obtained at a temperature of 30 o c. However, at 40 o c germination percentage decreased (86%). Whereas the lowest germination percentage (53%) was recorded at room temperature (25 o c).This means that, higher temperatures are more suitable for germination of sesame accessions. Among the three sesame accessions considered for the study, the highest and the lowest germination percentage was obtained by (9015) and the (241335) respectively. This indicated that there is variation among the sesame accession.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
