Abstract: A field experiment was conducted during rabi season of 2015-16 on clayey soil at Instructional farm, JAU, Junagadh to study the response of chickpea (Cicer arietinum L.) to plant growth regulators in randomised block design with three replications.The results revealed that higher values of growth parameters viz., plant height, number of branches per plant and yield attributes viz., number of pods per plant along with seed and stover yields were recorded under GA₃ 100 ppm at flowering stage, kinetin 10 ppm at flowering stage, GA₃ 50 ppm at flowering stage and kinetin 5 ppm at flowering stage over control. The highest net return of ₹ 74381 ha^-1 was realized with kinetin 10 ppm at flowering stage followed by the treatments T₅ (GA₃ 100 ppm at flowering stage), T₃ (GA₃ 50 ppm at flowering stage) and T₇ (kinetin 5 ppm at flowering stage) by recording net return of 73113, 70355 and 68004 ha^-1 respectively. However, maximum BCR of 3.51 and 3.31 was obtained with the treatment T₉ kinetin 10 ppm at flowering stage. It could be concluded that spraying of plant growth regulators kinetin or GA₃ at the time of flowering stage gave higher yield net return of chickpea under South Saurashtra Agro-climatic conditions.
