Abstract

Boro rice

Direct seeding

Salinity

Transplanting

Boro rice (irrigated rice) cultivation in the saline area of the coastal region of Bangladesh is limited because of increased soil and water salinity, lack of freshwater for irrigation and proper agronomic practices. An on-farm field trial was conducted in the farmer’s field at Dacope upazila in Khulna district of Bangladesh during the dry season (Boro) in 2022-23 to evaluate the growth and yield of Boro rice with different establishment methods and soil salinity dynamics with each type of establishment. The tested establishment methods were: (i) conventional tillage wet direct seeding (CTWDS), (ii) no-tillage wet direct seeding (NTWDS), (iii) conventional tillage transplanting rice (CTTP) and (iv) conventional tillage dry direct seeding (CTDDS). Grain yield was significantly higher (13-63%) in CTTP treatment than the other treatments. The direct seeding methods saved irrigation water but had a lower panicle-bearing tiller and grain per panicle which was related to lower yield. The direct seeding methods had also higher soil salinity. In conclusion, Boro rice cultivation with conventional transplanting (CTTP) method in the saline area maintained a higher yield and lower soil salinity than the direct seeding method.
