Abstract

The present study was carried out at Field experimentation, Sam Higginbottom University of Agriculture Technology and Science, Prayagraj, Uttar Pradesh during rabi season of 2020-2021, in order to standardize the suitable pre - sowing seed treatment of Radish. To investigate the Study on the Effect of various organic, growth regulators and chemicals treatments on growth, yield and yield attributing traits in Radish (Raphanus sativus). Experiment was laid out in Randomized Block Design (RBD) with Thirteen treatments and three replications. Different pre- sowing treatment with T0 un treated (control), T1- FYM, T2-FYM, T3- (Gibberellic acid @ 50ppm for 12hrs), T4 -(Gibberellic acid @ 100ppm for 12hrs), T5- (KNo3 @ 3% for 12hrs), T6 - (KNo3 @ 5% for 12hrs), T7- (Naphthalene acetic acid @ 50ppm for 12hrs), T8- (Naphthalene acetic acid @ 100ppm for 12hrs), T9- (Potassium chloride @ 3% for 12hrs), T10-(Potassium chloride @ 5% for 12hrs), T11- (ZnSo4 @ 3% for 12hrs), T12- (ZnSo4 @ 5% for 12hrs). It was found that pre- sowing treatment with T7 (Naphthalene acetic acid @ 50ppm for 12hrs) and T6 - (KNo3 @ 5% for 12hrs), significantly increased the emergence percent, Plant height, Days to 50percent flowering, Number of pods per plant, Seed yield per plant, Seed yield per plant, biological yield, Harvest index.
