A field experiment was conducted at Zonal Agricultural Research Station, UAS, GKVK, Bengaluru, Karnataka to study the effect of different approaches of fertilizer application on yield and nutrient use efficiency of finger millet crop under dry land condition. The results revealed that the soil test crop response (STCR)-targeted yield (30 q/ha) with integrated plant nutrient system (IPNS) approach resulted in significantly highest grain yield (41.42 q/ha) whereas highest stover yield was noticed with package of practices (PoP) approach (70.82 q/ha). Similarly significantly higher nutrient uptake was recorded in STCR-targeted yield with IPNS approach (30 q/ha) which was on par with PoP approach. However the highest nutrient requirement (NR) was recorded in STCR treatment either with inorganics or IPNS. Similarly the better profit was also recorded (VCR: 15.45) in STCR-targeted yield (20 q/ha) with inorganic approach.
