Abstract

A field trial was conducted to gauge the impact of value added NPK fertilizer,Zarkhez Plus, (N:08%;P:23%; K;18%) and biologically activated Zinc coated Urea (BAZU) maize.Treatments consisted; Control (T1), Straight Fertilizers (DAP, MoP, Urea) (T2), Zarkhez Plus + BAZUas 1/3rd replacement of Urea (T3), Zarkhez Plus + BAZU as 2/3rd replacement of Urea (T4), andZarkhez Plus + BAZU as 1/3rd replacement of Urea (T5). Results suggested that plant height, stemgirth, rows cob-1, grains row-1, grains cob-1, thousand seed weight were significantly improved by theapplication of Zarkhez Plus and BAZU. Grain yield was increased upto 30% with the application ofZarkhez Plus and BAZU compared to straight fertilizers. Application of BAZU beyond 1/3rd of thetotal N requirement did not increase the grain yield significantly but improved grain quality withhigher Zn and K contents. Maize grain yield can be significantly increased with the application ofZerkhez Plus and replacing 1/3rd in-season N requirement with BAZU.
