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.Keywords

A field experiment was conducted at Zonal Agricultural Research Station, University of Agricultural Sciences, GKVK, Bangalore to study the influence of soil and foliar application of different forms of fertilizers through different approaches on growth, yield and economics of hybrid maize in eastern dry zone of Karnataka. The experiment was laid out in RCBD with ten treatments and replicated thrice. The results revealed that soil test crop response (STCR) dose through soluble fertilizer with 3 splits and 3 sprays recorded higher growth and yield parameters like plant height (246.07 cm), number of leaves per plant (14.93), test weight (34.7 gm), cob length (19.23 cm) and yield parameters like grain yield (98.22 q ha-1) and stover yield (130.96 q ha-1). However, higher benefit : cost (B:C) was observed in recommended dose of fertilizer (RDF) through conventional fertilizer (4.20) followed by STCR dose through conventional fertilizers (3.62) and lower B:C recorded in treatment receiving soluble fertilizers irrespective of the forms and approaches of fertilizer application was mainly due to higher cost for soluble fertilizers compared to conventional fertilizers.Keywords
