Comparative Efficacy of Zn Supplement and Zinc Oxide Nanoparticles Over the Seed Germination of Lentil and Chick Pea

Abstract

The mineral nutrients are absorb from the soil by the roots, these are either macro or micro nutrients. Zinc is micro nutrients that help in several physiological process of plants and help in phyto hormone synthesis. The present Study includes the synthesis of ZnOPs by using Zinc oxalate decomposing method and these particles are characterized by UV-vis spectroscopy, and size was analyzed by Zeta analyzer. ZnOPs size was analyzed 65 nm. Seed germination was done by paper towel method. Soaking of seed was done in 100ppm, 500ppm and 1000ppm of ZnOPs and 100 ppm of ZnO supplement solution. After 5 day germination, germination percentage and seed vigor index (SVI) was calculated. It was observed that seed germination at 100 ppm is maximum in both the seed of Lentil (Lens esculentum Linn) and Chick pea (Cicer arietinum Linn). Seed vigor index was found increased at concentration of 100ppm. Presented study inferred that zinc provided as nanoparticle absorb more prominently than the traditional zinc supplement available in market at low concentration as the ZnOPs concentration increases the germination and seed vigor index retarded so it can be proposed that micronutrient in nano particles based formulation at lower concentration can provide better result in agriculture production.
