ABSTRACT

Soil test based fertilizer prescription equations under Integrated Plant Nutrition System (STCRIPNS)
were developed for potato on Ultisols. Making use of these equations, nomograms were
formulated for a range of soil test values and desired yield targets of potato. These equations
were validated on farmers’ fields and it was found that the per cent achievement of the targets
aimed was more than 90 and STCR - IPNS for 40 t ha-1 recorded relatively higher response ratio
(38.05 kg kg-1) and benefit - cost ratio (15.3) over other treatments indicating the validity of the
equations for prescribing fertilizer doses for potato.
