Abstract
Cauliflower (Brassica oleracea var. botrytis L.) is one of the most important winter vegetables among the Cole crops which belongs to the genus Brassica of the family Brassicaceae. The current research entitled, effect of titanium dioxide nanoparticles (TiO2-NPs) on soil physico-chemical characteristics in cauliflower (Brassica oleracea var. botrytis) at Prayagraj District of Eastern Uttar Pradesh was conducted during 2022-2023 on the Crop Research Farm of the Department of Soil Science and Agricultural Chemistry, Prayagraj (U.P). There were seven different treatments combinations included in the study comprising treatment T1 as control and treatment T2 to T7 contains 100% RDF through chemical fertilizers along with TiO2 application as seed treatment and foliar spray with concentration of 500, 1000 and 1500 ppm that were replicated three times in Randomized Block Design. The results demonstrated that available N, P & K were significantly affected and soil physical parameters (Bulk density, particle density and water holding capacity) were non-significantly affected by application of TiO2 nanoparticles applied as seed treatment or foliar spray.
