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 microbialinoculants and fertilizers on nutrient uptake and yield of sugarcane short crop. The experiment was laidout in randomized block design with ten treatments and replicated thrice. The treatments consist of 75%,100% and 125% RDF in combination of solid and liquid microbial inoculants (Gluconacetobacter, PSB andKSB). Data on N, P, K and S uptake by plant at different stages and yield were recorded. Results revealedthat application of 100% RDF along with sett treatment with liquid Gluconacetobacter @ 1 lit ha-1, PSB @ 1 litha-1 and KSB @ 1 lit ha-1 resulted significantly the highest N, P, K and S uptake by plant and seed cane yieldfollowed by 100% RDF + sett treatment with solid Gluconacetobacter @ 10 kg ha-1, PSB @ 1.25 kg ha-1 and KSB@ 1.25 kg ha-1.
