Effect of nano ZnO on growth and yield of sweet corn under South Gujarat condition

Abstract

A field experiment was conducted at College Farm of Navsari Agricultural University, Navsari to study the impacts of ZnO nanoparticles on growth and yield of sweet corn. Total twelve treatment of bulk ZnO, ZnSO4 and ZnO nanoparticles (ZnO-NPs) were taken as seed treatment and foliar application during experimentation. Among different treatments, foliar application ZnO-NPs (M3) @ 500 ppm gave significantly higher growth attributes viz. plant height at 60 DAS (173.67 cm) and harvest (198.85 cm), and yield attributes viz. number of cob per plant (1.73), cob length (30.13 cm) and cob girth (19.66 cm) as well as cob yield (18.98 t/ha) and straw yield (7.12 t/ha) of sweet corn.
