Description 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.
The microbial population in soil at harvest viz., bacteria, fungi,
actinomycetes and beneficial microorganisms like Azotobacter sp.,
Bacillus sp. and Pseudomonas sp. and available nutrient content in soil
after crop harvest i.e., nitrogen, phosphorous and potassium was also
found highest in the same treatment combination. The findings of this
study has clearly showed that combined application of biofertilizers with
recommended dose of NPK and enriched compost has resulted in
obtaining highest crop yields with a possible saving of 25% N and P
chemical fertilizers application.
