Abstract:
A field experiment was conducted on medium black calcareous soil at the Instructional Farm, College of Agriculture, Junagadh Agricultural University, Junagadh (Gujarat) during the summer season of 2019 to study the effect of plant growth regulators on nutrient content, uptake and quality of summer sesame in randomized block design with three replications, comprised with 10 treatments of three plant growth regulators spray at single stage as well as double stage. Foliar application of plant growth regulators improvement in nutrient content (N, P and K) and their uptake by seed and stover of sesame were noticed with foliar application of 100 ppm IAA at flowering and capsule formation stage followed by 100 ppm IAA at flowering stage as compared to control. This foliar spray of 100 ppm IAA at both stages gave higher values of quality parameters like chlorophyll content and oil content over rest of the treatments including Control.
