With a view to assess the extent of fertiliser requirement under Integrated Plant Nutrition System (IPNS) for rice-rice-residual pulse cropping sequence, field experiments were conducted in Typic Ustropept soils of Lower Bhavani Project area in Tamil Nadu. Making use of the data generated from the field experiments conducted on Inceptisol, targeted yield equations were developed for rice in kharif and rabi seasons. From these equations, the quantity of chemical fertilisers that could be adjusted to the levels and sources of organic manures was evaluated to be 38 kg N, 13 kg P:Os and 33 kg K20ha for fertilisers with GM: 10-12 kp P:Osha for temilisers with PB :40 kg N, 26 kg P:Os and 33 kg K0ha for fertilisers with GM plus PB.
