A field experiment was conducted at Zonal Agricultural Research Station, University of Agricultural Sciences, GKVK, Bengaluru to study the influence of different forms of fertilizers through different approaches on maize yield, uptake and nutrient balance on soils of Kandic Paleustalf. The results revealed that application of soluble fertilizers through STCR (90q ha-1) with 3 splits and 3 sprays of 19:19:19 recorded higher grain (98.22 q ha-1) and stover yield (130.96 q ha-1). Similarly, significantly higher nutrient uptake was observed where soluble fertilizers were applied as compared to conventional fertilizers applied either through RDF (Recommended Dose of Fertilizer) or STCR approach. These results clearly indicate that application of soluble fertilizers through STCR approach would help to get higher yield and higher nutrient uptake in maize crop.
