A field trial was conducted during Rabi season, 2020-21 to assess the perfomance of plant growth regulators on yield, nutrient uptake and quality of single cut oat. There were 11 treatments (triacontanol @ 10 ppm, triacontanol @ 20 ppm, mepiquat chloride @ 200 ppm, mepiquat chloride @ 300 ppm, salicylic acid @100 ppm, salicylic acid @ 200 ppm, NAA @ 20 ppm, fenoxaprop-p-ethyl @ 4 g a.i./ha, gibberellic acid @ 200 ppm, gibberellic acid @ 400 ppm and control) which were tested in RBD with three replications. Result revealed that green forage and dry matter yield was greater with mepiquat chloride @ 300 ppm than other treatments. However, application of NAA @ 20 ppm resulted higher nitrogen and potassium uptake and crude protein content and yield. Economic analysis indicated NAA @ 20 ppm gave the highest net return and benefit:cost ratio.
Key words: Oat, mepiquat chloride, NAA, yield, quality, economics
