Abstract

A field experiment was conducted for two consecutive years during 2019-20 and 2020-21 starting with kharif rice in the Instructional farm of OUAT, Bhubaneswar. The experiment was carried out in a Randomized Block design having 3 treatment combinations and 18 replications. Treatments consists of rice establishment method such as Direct Seeded Rice (DSR), Non puddled Transplanted Rice (NPTR) and Puddled Transplanted Rice (PTR). The soil was sandy loam in texture and slightly acidic in reaction with pH 5.43, low in organic carbon (3.75 g kg-1), low in available N (183 kg ha-1), medium in available P2O5 (14.17 kg ha-1) and high in K2O content (297.2 kg ha-1). In case of rice, higher yield was obtained under PTR method (5006 kg/ha) followed by NPTR (4841 kg/ha) and DSR (4643 kg/ha) method. But economically DSR was superior with B-C ratio of 1.79

Conclusion

From the above study, it can be concluded that Puddled transplanted rice performed superiorly in terms of growth parameters, yield attributes and yield over Non puddled transplanting method and Direct seeded rice was recorded with the lowest value. However, higher B/C ratio was obtained under DSR method probably due to lower cost of production as compared to the other methods
