Abstract: A pot culture experiment was demonstrated at Rajmohini Devi College of Agriculture research station, Ambikapur during Kharif season, 2018 in order study about limiting plant nutrients based on the crop response through nutrient omission technique in one of the major soil type of Surajpur district of Chhattisgarh. The main objective of this experiment was to identify yield limiting plant nutrient with the help of test crop i.e. rice (Oryza Sativa) variety MTU-1010 and then to demonstrate the identified limiting nutrient in farmer’s field with the help of wheat crop for the comparison of yield different in farmer’s filed and site specific nutrient management field. There were total 11 treatments of rice variety in which CRD (Completely randomized design) was used with include 3 replication. It was recorded that there was significant reduction in grain and straw yield of rice with the omission of N, P and S in soil when compared with the treatment that received all the nutrients i.e. SSNM. The reduction in yield was found to be more than 40.69% percent in case of N, 33.87% in case of P and 12.44 % in case of S in Inceptisol. The test was conducted to check limiting nutrients on farmer field where bulk soil sample was collected for pot culture study. The limited nutrient found was corrected by applying optimum dose of SSNM N-120, P2O5-80, K2O-50 and S-30 kg/ha. The percentage yield increase due to application of SSNM applied dose over farmer’s practice dose were 33.03-40%. This result conclude that application of N, P and S in Ineptisol and should be applied as per the recommended dose in order to attain maximum crop production.
