Abstract:

Studies on Soil Test Crop Response based Integrated Plant Nutrition System (STCR - IPNS) were conducted adopting the Inductive cum Targeted yield model, on Alfisols of GKVK, Bengaluru, during 2008–2012 in order to develop fertilizer prescriptions through IPNS for the desired yield targets of finger millet crop. For calculating the four important basic parameters viz., nutrient requirement (NR), contribution of nutrients from soil (%CS), fertilizer (%CF) and organic matter (%C-OM) were computed using the field experimental data. Making use of these basic parameters, the fertilizer prescription equations were developed under NPK alone and under IPNS for the desired yield targets of finger millet for a range of soil test values. The magnitude of response was higher under IPNS approach as compared to inorganics alone. The per cent reduction in NPK fertilizers under IPNS also increased with increasing soil fertility levels with reference to NPK. This could be achieved by integrated use of FYM with NPK fertilizers. Thus the Inductive cum Targeted yield model used to develop fertilizer prescription equations provides a strong basis for soil fertility maintenance consistent with high productivity and efficient nutrient management in “Precision Farming” for sustainable and enduring Agriculture.
