Optimization of irrigation (ETc) and nitrogen levels under drip fertigation in okra [Abelmoschus esculentus L.) using response surface methodology (RSM

[...]the application of response surface methodology facilitated the identification of the impact of each factor on individual responses, as well as the determination of optimal conditions that simultaneously maximize multiple desirable outcomes. Okra is extremely sensitive to soil moisture levels. Since both water stress and excess water impede plant development and fruit production, controlled irrigation is essential for high yield (Al-Harbi et al., 2008). [...]optimum irrigation plays an important role in crop yield, and accurate assessment of plant water status becomes crucial. In the pursuit of optimisation, several statistical methods such as response surface methodology, central composite design (CCD), and Box-Behnken design (BBD) have been developed to achieve improved outcomes within reduced timeframes. [...]they serve as a comprehensive and versatile tool for constructing empirical models and analysing the effects of many components, as well as examining the interactions among variables and assessing their statistical significance (Chen et al., 2022).
