Abstract:

A field experiment to study the “Comparative efficiency of organics and biofertilizers on growth and yield of maize (Zea mays L.)” was conducted during Kharif 2011 at farmer field in Beluguli village, Chikkanayakanahalli taluk (Tumkur district). The maize cultivar Nithyashree (NAH 2049) was used in the study. The field experiment was laid out in Randomized Complete Block Design with fourteen treatments and three replications. Results of the treatment (T₁₃) having recommended dose of NPK + Azotobacter chroococcum + Bacillus megaterium + Pseudomonas fluorescence + enriched compost has showed highest plant height at 30, 60, 90 days after sowing and at harvest (120 days) (31.70, 180.93, 186.07 and 188.13 cm respectively). The highest total dry  matter production at harvest (375.80 g) and yield parameters like Weight of cob (207.63 g), Grain yield per  plant (158.93 g), Grain yield per ha (54.53 q) and Test weight of seeds (33.10 g) was also found highest in this treatment and available nutrient content in soil after crop harvest i.e., nitrogen (185.40 Kg  ha^-1), phosphorous (38.83 Kg ha^-1) and potassium (181.47 Kg ha^-1) was also found highest in the same treatment combination.
