Controlled agricultural trial demonstrates improved yield and water-use efficiency in potato crops with auxin and weed management, suggesting optimized agronomic protocols.
The application of Indole-3-Acetic Acid in potato production can improve potato growth and development. Experimentation is needed to fully understand the optimal conditions and dosage for Indole-3-Acetic Acid application across different potato varieties. This study assessed the effects of the application of Indole-3-Acetic Acid and Metribuzin on potato (Solanum tuberosum L.) in Kerman, Iran. The experimental factors consisted of: 1) potato cultivars Milva and Sante, 2) application of Indole-3-Acetic Acid at doses of 0, 200, and 400 mg l−1, and 3) pre-emergence and two-step split application of Metribuzin, hand weeding, and no-weed control. Both IAA application and weed control significantly increased tuber-specific gravity, yield, shoot biomass, starch content, protein content, and water-use efficiency (p < .05). The 400 mg l−1 IAA treatment, combined with split-application Metribuzin or hand-weeding, delivered the highest tuber yield of 38,055 kg ha−1, which was ~96% higher compared to the lowest yield of 18,825 kg ha−1 observed in the untreated control. Foliar application of IAA at 400 mg l−1, when integrated with effective weed management, enhanced growth and yield in Milva and Sante potatoes (no significant differences were observed between the cultivars), supporting optimized agronomic practices for improved production.
