A field experiment was conducted to work out the water productivity, economics and energetics of basmati rice ( Oryza sativa L.)wheat [ Triticum aestivum (L.) emend. Fiori & Paol] sequence under different methods of crop es- tablishment during 2005-06 and 2006-07. The treatments included combinations of two crop establishment meth- ods of basmati rice (direct seeded and transplanted) and three seeding techniques of succeeding wheat (conven- tional, bed planting and zero tillage). Productivity of basmati rice-wheat sequence was significantly higher with transplanted basmati rice (TPBR) than direct seeded basmati rice (DSBR) irrespective of seeding technique of succeeding wheat. However, crop establishment methods of wheat did not show any significant impact on total productivity of basmati rice-wheat sequence during both the years. Total water use was 9.5 and 8.2 per cent higher in TPBR-wheat sequence than DSBR-wheat sequence during 2005-06 and 2006-07, respectively. In this sequence the highest net return was obtained from TPBR-zero till sown wheat sequence, which was closely fol- lowed by TPBR-conventionally sown wheat sequence but both gave more net returns than DSBR-zero till sown wheat sequence. The highest energy output was recorded in TPBR-conventionally sown wheat, while energy use efficiency was maximum in TPBR-zero till sown wheat, during both the years because of lowest energy input in zero till sown wheat than conventional and bed planting.References
