Evaluation of seed priming and coating on germination and early seedling growth of sesame (Sesamum indicum L.) under laboratory condition at Gondar, Ethiopia

Abstract

The laboratory test was conducted in 2016 at Gondar seed laboratory with the objective of evaluating of seed priming, pesticide dressing and coating on germination of sesame (Sesamum indicum L.) on laboratory at Gondar, Ethiopia. Twelve treatments, untreated seed (T1), hydro-primed seed (T2), seed primed with CaCl2 (T3), seed treated with dynamic (T4), hydro-primed seed + treated with dynamic (T5), seed primed with CaCl2+ treated with dynamic (T6), seed treated with dynamic + disco (T7), hydro-primed seed + treated with dynamic + disco (T8), seed primed with CaCl2 + treated with dynamic + disco (T9), seed treated with dynamic + disco +genius coating(T10), hydro-primed seed + treated with dynamic +disco + genius coating(T11) and seed primed with CaCl2 + treated with dynamic + disco + genius coating (T12) were tested using completely randomized design (CRD) with four replications. Physiological quality data like germination percentage, root length, shoot length and vigor index were taken. Analysis of variance for all parameters was computed with SAS version 9.0 and mean separation was using the least significant difference test (LSD) at 5% and 1% level of significance. The study revealed that germination percentage, root length, shoot length and vigor index of sesame were significantly (p < 0.01) affected by seed priming and coating treatments. From this experiment, higher germination percentage (91.50%) was recorded by primed seeds with water. However, the root length (4.78 cm), shoot length (6.33 cm) and vigor index (928.48) of sesame was higher for seeds coated with dynamic + disco.
