Dormancy Breaking in Okra: Implication on Agricultural Productivity.

Abstract:Okra (Abelmoschus spp) is a widely cultivated vegetable known for its nutritional benefits and adaptability. However, optimising its growth and yield can be challenging due to its hard seed coat. Dormancy in okra poses a significant challenge to agricultural productivity by delaying germination and reducing yield. The study was conducted in the seed testing laboratory of the National Centre for Genetic Resources and Biotechnology (NACGRAB), Apata, Ibadan. The objective was to evaluate the effectiveness of hot water treatments as a technique to overcome dormancy in five accessions of okra and to enhance agricultural productivity. The experiment was arranged in 5 × 8 factorial laid in a completely randomized block design with three replications. The factors were five accessions of okra (NGB00496, NGB00303, NGB00302, NGB00469, NGB00323) and eight hot water treatments (30°C, 40°C, 50°C, 60°C, 70°C, 80°C, 90°C, 100°C) for 15 seconds. Data collected on germination rates, seedling vigour, and yield were compared with untreated seeds (control).
