- Abstract
To study the influence of the application of super absorbent polymer on the growth and yield of maize and better management of water deficit conditions, a field experiment was conducted in the summer season of 2021 at Qlyasan Agricultural Station-Sulaimani. The experiment was laid out as a split-plot design with three replications. The irrigation levels (I1100% Field capacity (FC), I2 50% FC, and I3 25% FC) were allocated in main plots, while polymer levels, (0, and 4Kg. ha-1 SAP) noted P0 and P1, were administered in addition to two maize hybrids (H1 and H2). According to these considerations they were distributed in subplots. Results of super absorbent polymer (SAP) significantly influenced criteria related to physiological growth of both maize hybrids displaying better development of leaf area, higher leaf relative water content (RWC) from vegetative growth stage while the maize plants were with five leaves (V5) up to the first stage of reproductive growth period (R1), as well as appropriate root fresh weight, and root dry weight. The reproductive criteria of yield and yield components, biological yield, and harvest index were improved in response to the impact of SAP. The application of SAP on yield and yield components mitigated the stress conditions created with water deficit levels of 50% FC, and 25% FC, so from the study outcomes can be concluded that there is an opportunity for growth the cultivation area of maize through utilizing of SAP in regions that suffer from water deficit situation.
