A pilot project was undertaken during kharif at Belaguthi village of Honnali taluk in Davanagere district, Karnataka state, India to study the spatial variability of nutrient in maize fields and to recommend nutrients for maize crop based on STCR approach. Georeferenced one hundred and forty two soil samples were drawn from fields of 88 farmers. Results of soil analysis revealed that the soils were acidic to neutral in reaction (), majority of soil samples (98 per cent) were low in available nitrogen, low to high (low: 13%, medium: 40%, high: 46% area) with respect to phosphorus and medium to high (medium: 75%, high: 23% area) in potassium status. Nutrient recommendation generated by adopting STCR approach revealedthat an addition of 15 kg ofNPK ha-1 is required to match the crop need to achieve the target yield of 50 q/ha over state recommendation for maize crop ( kg NPK ha-1). Maize fields receiving fertilizers in accordance with the site specificity have achieved largest yield ( q/ha) followed by application of recommended fertilizers ( q/ha).
