Growth and yield of hybrid maize (Zea mays L.) an influenced by levels of phosphorus with PSB+VAM seed inoculation

Abstract

A Field experiment was conducted in Kharif season 2015 at crop Research Farm, Department of Agronomy, Naini Agricultural Institute, SHUATS, Allahabad (U.P) to study the effect of levels of phosphorus with VAM and PSB on growth and yield of hybrid maize (Zea mays L.). The treatments comprised of nine treatments, consisting of three phosphorus levels (40, 60 and 80 kg ha-1) and seed inoculation with which was laid out in Randomized Block Design with three replications, in a plot size of 4 x 3 m with a spacing of 60 cm x 30 cm. The result revealed that the treatment T6 (60 kg ha-1of phosphorus + RSB + VAM) produced significantly higher plant dry weight (51.72 g), grain yield (4955.67 kg ha-1), harvest index (40%) and B:C Ratio (1.41) in hybrid maize cultivation.
