abstract
A field experiment was conducted at Agricultural College Farm, Bapatla during 2020 and 2021. To study the “Effect of biofertilizers and inorganic fertilizers on growth, yield and quality of kharif maize” The experiment was laid out in randomized block design (RBD) with seven treatments and replicated thrice. The treatments consisted of T₁- Control; T₂- 100% RDF; T₃- 125% RDF; T₄ – 100% RDF + VAM; T₅- 100% RDF +VAM + Azospirilylum + PSB; T6- 75% RDF + VAM; T₇- 75% RDF + VAM + Azospirillum + PSB. The results revealed that plant height, drymatter production, grain and stover yield and quality parameters of maize were significantly higher with 100% RDF +VAM + Azospirillum + PSB (T₅) and it was on par with T₇ (75% RDF + VAM + Azospirillum + PSB), T₃ (125% RDF) and T4 (100% RDF + VAM). lowest plant height, drymatter production, grain and stover yield and quality parameters are recorded T₁(control) at all three stages of crop growth during both years of study. Present study highlights the need of use of biofertilizers along with inorganic fertilizers to enhance the increased plant height, growth and drymatter production, yield and quality of kharif maize. Biofertilizers play significant role in improve plant metabolic activities and increased yield.
