Study the Effect of Adding Chemical Fertilizer and Spraying with Growth Regulator (Atonik) on the Growth, Production and Quality of the Okra Plant (Abelmoschus esculentus L.)

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 ۲۰۲۳-۲۰۲۴ 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: ۰, ۷۰, ۱۴۰ g/l) and Atonik (T: ۰, ۵, ۱۰ 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 ≤ ۰.۰۵. Chemical fertilizer (D) significantly increased plant height (۱۵۸.۲۲ cm), leaf number (۱۳۹.۶۶), yield (۱۱.۳۲۸ g/plant), pod count (۵.۷۴۰), carbohydrates (۰.۲۶۴%), and phosphorus (P%). Atonik (T) enhanced fruit weight (۳.۱۵۴ g), nitrogen (N%, ۱.۰۹۳), and potassium (K%, ۱.۸۶۷). The interaction (T×D) showed D۲T۰ improved height, pod count, and N%; D۲T۱ boosted fruit weight and yield; D۱T۱ increased K%; and D۲T۲ elevated P%. Combining chemical fertilizer (۱۴۰ g/l) and Atonik (۵–۱۰ mg/l) optimized okra growth, yield, and nutrient content, demonstrating their synergistic potential in enhancing okra production.
