Abstract:
The field experiments were conducted on a Typic ustropept soils of Puducherry by adopting the inductive cum targeted yield model, and fertiliser requirements were quantified for bhendi based on soil test and yield target. The basic parameters viz. nutrient requirement (NR), contribution of nutrients from soil (Cs), fertilizer (Cf) and farmyard manure (Cfym) were computed from field experimental data. Using these basic parameters, the fertiliser prescription equations were developed under integrated plant nutrition system (IPNS) and nomograms were formulated for the desired yield target of bhendi for a range of soil test values. The quantity of fertilizers that could be contributed by FYM @ 12.5 t ha-1 for bhendi were evaluated as 50, 28 and 43 kg fertilizer N, P2O5 and K2O respectively, when applied along with the NPK fertilizers as per soil test and desired yield target.
