Effect of hybrid varieties and seaweed extracts (SoliGro Gr) with nitrogen management on yield and economics of maize (Zea mays L.)

Abstract

A field experiment was conducted at the Student’s Instructional Farm of Chandra Shekhar Azad University of Agriculture and Technology, Kanpur during the kharif season of 2018 and 2019 to evaluate the effect of different hybrid varieties and seaweed extract (SoliGro Gr) with nitrogen management on yield and economics of maize. The experiment was laid out in Factorial Randomized Block Design with two factors, one having three levels and the other having six levels, replicated thrice making eighteen treatment combinations assigned to 54 plots. The hybrid variety DKC-7074 produced significantly highest grain yield (36.31q/ha) including significantly higher gross return (Rs. 66644.25/ha), net return (Rs. 33147.75/ha) and benefit cost ratio (1.98). The application of SoliGro Gr with 125% N used in two split doses as basal and top dressing produced significantly highest grain yield (36.05 q/ ha) including significantly higher gross return (Rs. 66274.83/ ha), net return (Rs. 31964.83/ha) and benefit cost ratio (1.93). Therefore, in the case of interaction effect of the treatment combination DKC-7074 X SoliGro Gr with 125% N (basal + top dressing), significantly better grain yield, higher gross return, net return and benefit cost ratio was noted.
