Pre-sowing Seed Treatment of Chemicals, Botanicals, Plant Growth Regulators on Growth, Yield and Yield Attributing Traits of Linseed (Linum usitatissimum L.) under Late Sowing Conditions var. Uma

Abstract

The experiment was conducted at Field Experimentation and Farm Research Centre, Department of Genetics and Plant Breeding, (Rabi season, 2020-21) Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj (U.P.). The experimental material for present experiment comprised of thirteen priming treatments on linseed seed. The experiment was conducted in Randomized Block Design (RBD) with three replications. Linseed seeds of variety Uma was subjected to various pre sowing treatments like MnSO4,FeSO4 Pongamia leaf powder, Arappu leaf powder, Notchi leaf powder, Kinetin at various concentrations along with distilled water control. The study revealed that linseed seeds treated with Pongamia leaf powder T6 (5%) showed maximum field emergence (97.48%), plant height 60 days (77.46cm) and 90 days (92.69cm) no of primary branches per plant (5.97),no of seeds per capsule (8.95),no of capsules per plant (25.91), test weight (9.43), seed yield per plant (4.78g), seed yield per plot (128.4g), biological yield (8.26), harvest index (79.53) and reduced days to 50% flowering (65.89), days to maturity (115.89), followed by kinetin T12 50(ppm), in comparison to control T0.
