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. | Seed priming with nano boron nitride increases the performance of sunflower Helianthus annuus L. seedlings
