Investigation was conducted during kharif season of 2016 at Instructional cum Research Farm, S.G. College of Agriculture and research station, Jagdalpur (C.G.). The soil of experimental field was sandy clay loam in texture and available N was low and, P and K were medium. The experiment was laid out in split plot design with two factors namely tillage practices and different conservation farming with three replications. The treatment consisted of three tillage practices viz. T1- Conventional tillage, T2 –Minimum tillage and T3 – Summer ploughing and five conservation farming viz. C1-Opening conservation, C2-Intercropping with redgram, C3-Mulching, C4-Herbicide application, C5-Combination of all treatments (C1+C2+C3+C4). Two crops were taken as a taste crop viz. finger millet cv “GPU 28” and redgram cv “Rajeevlochan”. The result revealed that summer plouging showed significantly highest available nitrogen and phosphorus but available potassium, pH, organic carbon and EC were recorded non-significant effect. Minimum tillage recorded significantly higher soil moisture and bulk density. N uptake and content recorded significantly highest in summer ploughing and P uptake and content recorded higher in minimum tillage but K uptake was not found significant due to tillage system in grain. In straw, N uptake was significantly higher in summer ploughing but N content was higher in conventional tillage whereas, P and K were found non-significant effect in tillage practices.
