ABSTRACT

An investigation was carried on “Impact of conjunctive use of organic and inorganic fertilizers on nutrient availability in soil, yield and yield attributes of maize (Zea mays L.)” during kharif 2024 at wet land farm of S.V. Agricultural College, Tirupati. The experiment was carried out in randomized block design with three replications consisting of ten treatments with 75% and 100% RDF along with poultry manure, FYM and microbial inoculum (Azospirillum, PSB and KSB). Data indicated that application of 100% RDF + Soil application of liquid biofertilizers viz., Azospirillum, PSB and KSB @ 1.25 litres ha-1 each (T₅) resulted in the highest grain yield and stover yield. Yeild attributes like cob length, number of kernels per row, number of kernel rows per cob were found to be highest with application of 100% RDF + soil application of liquid biofertilizers viz., Azospirillum, PSB and KSB @ 1.25 litres ha-1 each (T₅). The highest available nutrients viz., N, P, K were noticed with application of 100% RDF + Soil application of liquid biofertilizers viz., Azospirillum, PSB and KSB @ 1.25 litres each (T₅).

KEYWORDS: Liquid Biofertilizers, kernel, yield, growth.
