Abstract

Okra (Abelmoschus esculentus L.) has antidiabetic, antioxidant, anti-inflammatory, and hypolipidemic effects. Its polysaccharides and flavonoids lower blood glucose, while antioxidants reduce oxidative stress. It aids digestion, protects the liver and stomach, and has antimicrobial properties against pathogens like S. aureus and E. coli. This study investigated the effects of chemical fertilizer and Atonik growth regulator on okra growth, yield, and quality during the 2023-2024 season. The study aimed to evaluate how different fertilizer levels and Atonik concentrations influence okra's agronomic and biochemical traits. The experiment was conducted in an open field at Samarra University, Iraq, using a randomized complete block design (RCBD) with two factors: chemical fertilizer (D: 0, 70, 140 g/l) and Atonik (T: 0, 5, 10 mg/l). Data on plant height, leaf count, yield, pod number, and nutrient content were analyzed using GenStat, with means compared via LSD at p ≤ 0.05. Chemical fertilizer (D) significantly increased plant height (158.22 cm), leaf number (139.66), yield (11.328 g/plant), pod count (5.740), carbohydrates (0.264%), and phosphorus (P%). Atonik (T) enhanced fruit weight (3.154 g), nitrogen (N%, 1.093), and potassium (K%, 1.867). The interaction (T×D) showed D2T0 improved height, pod count, and N%; D2T1 boosted fruit weight and yield; D1T1 increased K%; and D2T2 elevated P%. Combining chemical fertilizer (140 g/l) and Atonik (5–10 mg/l) optimized okra growth, yield, and nutrient content, demonstrating their synergistic potential in enhancing okra production.
