Abstract
An experiment was conducted to study the effect of seed invigoration with inorganic nanoparticles on plant growth and seed yield of chilli. Seed invigoration with nano particles of ZnO and TiO2 was found to be beneficial in improving yield and yield attributes. Seed treatment with nano ZnO @ 1300 mg kg-1 of seed and nano TiO2 @ 900 mg kg-1 exhibited increased plant height, fruits per plant, fruit length, fruit yield, number of seeds per fruit and seed yield.
Highlights
The production of high-quality seeds is one of the most strategic resources for higher yield

Summary
The production of high-quality seeds is one of the most strategic resources for higher yield. Seed treatments can be generally defined as, all operations that are executed on seeds after taking them from mother plant. These practices aim to improve yields by protecting from insects, diseases and ensuring uniform crop stand across a variety of environmental conditions and soil types. Since the treatments are applied to seeds, the land area which is exposed to active ingredients is reduced. The positive effects of nanoparticles include enhanced germination per cent, length of root and shoot and vegetative biomass of seedlings in many crop plants (Agarwal & Rathore, 2014). Use of metal based nanoparticles like Gold, Titanium, Copper and Zinc are increasing exponentially because of their enhanced biological activities and physiochemical properties
