Influence of Chemicals, Botanicals and Growth Regulator Treatments on Plant Growth and Yield Attributing Traits of Lentil (Lens culinaris L.) Variety: K-75

The experiment was conducted in post graduate Seed Testing Laboratory and Field Department of Genetics and Plant Breeding, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj (U.P) during Rabi season 2020-2021, in order to standardize the suitable pre-sowing seed treatment for Lentil (K-75). Different pre-sowing seed treatments viz.,T0-Control (untreated), T1- KCL @1%, T2- KCL @ 3%, T3- KNO3 @ 1%, T4- KNO3 @ 3%, T5- Panchagavya @ 2%, T6 – GA3 @ 20ppm, T7 – Panchagavya @ 4%, T8 – GA3 @ 10ppm,T9 – Panchagavya @ 6%,T10 – Tulasi Leaf Extract @ 2%, T11 – Tulasi Leaf Extract @ 4%,T12 – Tulasi Leaf Extract @ 6% were evaluated by screening of 12 hour. It was found that all the pre-sowing seed treatments recorded the significant difference with that of control. In field condition highest field emergence percentage,yield and yielding attributes was found in T7 -Panchagavya @ 4%. Pre-sowing seed treatment with Panchagavya @ 4% followed by GA3 @ 10 ppm, Panchagavya @ 2%, KCL @ 1% significantly increased the germination and yielding attributes of Lentil. Pre-sowing seed treatments with Panchagavya (4%) and GA3 (10ppm) resulted in maximum increase in field emergence, vigour of Lentil seeds and found to be lowest in control seeds. Pre-sowing seed treatment that leads to a physiological condition that allows the seed to germinate more effectively and no costly equipment and chemical requirements could be used. Hence it is a simple method for overcoming weak germination and seedling establishment and helps to preserve agriculture and economical, non-toxic, eco-friendly sources.
