The investigation was carried out for evaluate effect of humic acid and NAA on oil content of linseed at the experimental farm of Agricultural Botany Section, College of Agriculture, Nagpur during year 2015-16. Experiment treatment included different concentrations of humic acid (300, 350, 400, 450 and 500 ppm) and NAA (25 and 50 ppm) individually and in combinations were tested with two times foliar spraying method (35 and 55 DAS). The obtained results revealed that 350 ppm HA through VCW + 50 ppm NAA followed by 300 ppm HA through VCW + 50 ppm NAA had significant promotive effect on oil content in seed, number of capsules plant-1 , number of seeds capsules-1 , 1000 seed weight, seed yield plant-1 , plot-1 , ha-1 when compared with the control treatment.
