Abstract: An pot experiment was conducted at experimental research station Rajmohani Devi College of Agriculture and Research Station, Ambikapur during Kharif season, 2018 to study Site-specific nutrient management using nutrient omission technique in two major soil types of Koriya district of Chhattisgarh’’. The objectives of the experiment were to identify the yield-limiting nutrients using the missing element technique with rice as a test crop and to demonstrate the identified limiting nutrients on farmer’s field with the wheat crop to observe the yield difference with those of farmer’s practice. A total of 11 treatments were tested with rice (MTU-1010) as a test crop, laid out in CRD with three replications. Grain and straw yields of rice were significantly reduced with the omission of N, P, and S in Inceptisol soil comparison to the treatment receiving all the nutrients (SSNM).The yield reduction is found to be more than 54% in the case of N, 33% in the case of P, and 15.39% in S case of Inceptisols during Kharif in rice crop. These limiting nutrients were tested on farmer's fields with wheat crop during Rabi season, 2018-19 where bulk soil samples were collected for pot culture study. The limiting nutrients were corrected with optimum doses (SSNM) as N -120, P2O5-80, K2O-50 and S-30 kg/ha along with Zn @ 5 kg/ha. Wheat grain yields recorded with SSNM dose were 34% higher than that with FPD.
