Effect of different levels of phosphorus and biofertilizers (PSB and VAM) on growth and yield of hybrid maize (Zea mays L.)

The field experiment was conducted during kharif season of 2015 at Crop Research Farm SHUATS, Allahabad. The experiment was carried out to find the performance of different Levels of phosphorus and biofertilizers (PSB and VAM) on Growth and Yield of Hybrid Maize, which laid out in Randomized Block Design (RBD) & replicated thrice. The experiment finding revealed that the treatment T9 (80 kg ha-1 P + PSB+VAM) significantly performed better than all other treatments viz; Plant height (187.08 cm), Number of leaves (10.58), while treatment T6 (60 kg ha-1 P + PSB+VAM) performed better than all other treatments viz; Dry weight (51.72 g), Cob length (18.94 cm), Cob weight (241.08 g), Grain yield (4.95 t ha–1), Straw yield (7.45 t ha–1), Test weight (28.10 g) and Harvest index (39.98%). While the same treatment T6 (60 kg ha-1 P + PSB+VAM) recorded highest gross return (65653.75 Rs ha–1), net return (38416.75 Rs ha–1) and B: C ratio (1.41), however treatment T3 (40 kg ha-1 P + PSB+VAM) was found statistically at par with treatment T6 (60 kg ha-1 P + PSB+VAM).
