Effect of Spraying with Brassinolide on Yield and its Components of Sesame Cultivars

Abstract To investigate the impact of brassinolide spraying on sesame yield and its components, a field experiment was conducted in summer 2022 Karma region Anbar Governorate. Three independent replicates were using randomized complete block design (RCBD) with split-plot layout. The cultivars (Sumer, Rafidain, Wadea, Hadd) occupied sub-plots, while concentrations (0.0, 0.5, 1.0, 1.5 mg L −1 ) comprised main plots. results showed that Hadd cultivar best terms harvest index (22.9%), number capsules produced by each plant (390.2 plant-1), seeds capsule (96.42 ), total seed (2685.3 kg ha-1). Sumer only where average weight thousand greater than any other (3.86 g). Brassinolide at concentration resulted an 273.9 per plant, 95.50 capsule, 4.11 grams seeds, 2226.4 kilograms hectare (kg) output, 10.294 tons (t) biological production, 26.06%. had significant interaction production (3017.9 ha (13.707 index.
