A field experiment was conducted at Agricultural Research Station, Bhavanisagar, Tamil Nadu, India during summer 2018 and 2019 to study the influence of moisture stress management practices on plant growth and yield of maize. Study revealed that, irrigation scheduling at IW/CPE 1.0 produced higher plant height (217.6 cm), leaf area index (3.77), dry matter production (16159 kg ha-1) and yield (6715 kg ha-1) and was comparable with IW/CPE ratio of 0.8. Among the moisture stress management practices foliar application of PPFM 1% at 25 and 45 DAS recorded significantly higher plant height (209.7 cm), leaf area index (3.62), dry matter production (15505 kg ha-1) and yield (6381 kg ha-1). Higher net return (55535 Rs. ha-1) and benefit cost ratio (2.71) was realized under IW/CPE 0.8. In moisture stress management practices foliar application of PPFM @ 1% recorded higher net return (51455 Rs. ha-1) and benefit cost ratio (2.56). Results from the study indicated that, irrigating at IW/CPE ratio of 0.8 was good enough to produce maximum yield and net return in normal water availability condition. While under water scarcity condition IW/CPE ratio of 0.6 coupled with foliar application of PPFM 1% at 25 and 45 DAS was more reliable for sustaining yield and net return.
