A field experiment was conducted at Pandit Jawaharlal Nehru College of Agriculture and Research Institute, Karaikal to study the effect of plant growth regulators on growth and yield of sesame (Sesamum indicum L.) during summer 2021. The field experiment with thirteen treatments was conducted on loamy sand soil in a randomized block design (RBD) replicated thrice. The treatments included four plant growth regulators at various concentrations (NAA 50 ppm, NAA 100 ppm, CCC 100 ppm, BA 5 ppm and HA 500 ppm) and water spray at two levels of application (one spray – at flowering stage and two sprays – at flowering and capsule formation stages) and an unsprayed control. The results revealed that spraying NAA 100 ppm twice recorded the highest values for plant height, leaf area index, dry matter production and number of branches per plant followed by single spray of humic acid 500 ppm at flowering stage. The highest number of capsules per plant was recorded with application of NAA 100 ppm twice at flowering and capsule formation stages. Application of NAA 100 ppm twice recorded significantly higher seed (633 kg ha-1) and haulm (1296 kg ha-1) yields as compared to other growth regulators.
