Continuous cereal based cropping system and use of in-organic nitrogen (N) degrades soil fertility and productivity. The present study was designed with the objective in mind to sought out proper combination of both tillage practices (shallow, medium and deep plough) and nitrogen (With and without 120 kg N ha^-1) applications in different crop sequences (CS). Yield and yield components of wheat were studied in the field for two consecutive years. All the studied parameters of wheat crop were significantly (p<0.05) affected by tillage practices, crop sequence with and without added N and year as source of variation. When averaged across crop sequence with and without added N, shallow tillage practice was comparatively superior to medium and deep tillage. Likewise, by averaged across different tillage practices, cropping sequence having sesbania as summer legume with added N (CS6) was better in performance when compared with other cropping sequences with no additional in-organic N. Similarly, significant differences (p<0.05) were found in 2016-17 for almost all the studied parameters of wheat crop compared to 2015-16. Therefore, inclusion of summer legumes (Sesbania) in cereal based cropping system under shallow tillage practices and optimum N addition could be the best management strategy for sustainability in term of soil fertility and crop productivity.
