Quality and yield of hybrid rice (Oryza sativa L.) as affected by foliar application of growth regulators

A field experiment was conducted on hybrid rice crop during Kharif seasons of 2015 and 2016 comprising of treatments such as Control, GA₃ 20 ppm, GA₃ 40 ppm, IAA 25 ppm, IAA 50 ppm, NAA 10 ppm, NAA 20 ppm, Triacontanol 5 ppm, Triacontanol 10 ppm, Cycocel 3000 and Cycocel 4000 ppm, with two foliar sprays (first spray at tillering and second at flowering stages). The observations were recorded at harvest stage of crop growth except canopy temperature depression (⁰C) which was recorded at flowering stage. The results showed that IAA 50 ppm gave significant response for maximum traits in comparison to control.
