The effect of soil applied biochar with recommended dose of fertiliser and biofertiliser was investigated on maize in Alfisols of Thoothukudi District. The field experiment was laid out in a randomized block design with combination of two levels of fertiliser (75% & 100% Recommended Dose of Fertiliser) and biochar (5 t ha-1 & 7.5 t ha-1) with biofertiliser (Azophos 4 pockets ha-1) replicated as thrice. Application of biochar with recommended dose of N, P2O5 and K2O fertiliser increased the yield components of maize viz., hundred grain weight (38.9g), cob length (23.5cm), cob weight (310g), grain yield (8100 kg ha-1) and stover yield (12,150 kg ha-1) and also quality trait such as crude protein content. Higher yield and quality was obtained from the combination of 5 t ha-1 plus 100 per cent recommended dose of N, P2O5 and K2O plus biofertiliser on maize.
