Abstract:

A laboratory investigation was initiated to examine the effect of “Seed priming with nano boron nitride increases the performance of sunflower (Helianthus annuus L.) seedlings” at Department of Agronomy, University of Agricultural Sciences, GKVK, Bengaluru. The experiment was arranged in completely randomized design with five replications. Boron nitride (particle size 70 nm) is used as source of nano boron and Borax [sodium tetraborate (Na2B4O7•10H2O)] was used as a source of boron. The treatments consist of seed priming with borax at 0 %, 0.2%, 0.4%, 0.5% and 0.6 % borax and nano boron. Significantly higher seed germination (88.3%), root length (5.65 cm and 11.4 cm respectively), shoot length (7.35 cm and 18.14 cm respectively) and vigour index (1286 and 1773, respectively) at 8 and 15 days after sowing were recorded in seed treatment with nano boron at 0.2 % seed priming. Significantly lower seed germination (76.7 %), root length (0.58 cm and 1.28 cm respectively), shoot length (1.03 cm and 5.66 cm respectively) and vigour index (121 and 532 respectively) at 8 and 15 days after sowing were recorded in seed priming with 0.6% borax treatment.
