ABSTRACT

A field experiment was conducted at Agricultural Research Station, Perumallapalle, Tirupati, Acharya N.G. Ranga Agricultural University, Andhra Pradesh, India during 2021-22 to study the effect of fertilizers and microbial inoculants on growth and yield of sugarcane short crop. The experiment was laid out in randomized block design with ten treatments and replicated thrice. The treatments consists of 75%, 100% and 125% RDF in combination of solid and liquid microbial inoculants (Gluconacetobacter, PSB and KSB). Data on dry matter production, yield characters and yield parameters were recorded. Results revealed that 100% RDF along with sett treatment with liquid Gluconacetobacter @ 1 L ha-1, PSB @ 1.25 L ha-1 and KSB @

1.25 L ha-1 resulted significantly the highest dry matter production (6684, 29821, 37530 kg ha-1 at tillering, grand growth and harvest stages, respectively). It also enhanced tillering (119364 ha-1), stalk population (93465 ha-1), cane length (248 cm) and cane yield (97 t ha-1).
