A field experiment was conducted at Zonal Agricultural Research Station, UAS, GKVK, Bengaluru, Karnataka to study the influence of different approaches of fertilizer application using soluble and conventional fertilizers on yield, nutrient requirement and economics of cabbage under drip fertigation. The results revealed that significant higher marketable cabbage yield of 62.55 t ha^-1 was recorded in LMH approach followed by STCR inorganic approach (62.03 t ha^-1) using soluble fertilizers and STCR integrated plant nutrition approach (61.31 t ha^-1)  using soluble fertilizers. Similarly higher nutrient uptake (N, P₂O₅ and K₂O kg ha^-1) was recorded in LMH approach followed by STCR inorganic approach using soluble fertilizers and STCR integrated plant nutrition approach using soluble fertilizers. However, nutrient requirement (NR) of N, P₂O₅ and K₂O was highest in absolute control followed by LMH approach. Value cost ratio (VCR) worked out was found to be higher (13.37) in STCR inorganic approach using conventional fertilizers followed by STCR integrated approach using conventional fertilizers.
