Notes.

Crop planting techniques i.e., CE1-Conventional puddled transplanted rice (CT- TPR), CE2- Wide bed Transplanted rice (W Bed-TPR); Fertilizer management strategies i.e., N1- Control, N2- 100% RDF + ZnSO 4 25 kg ha−1, N3- 125% RDN + ZnSO 4 25 kg ha−1, N4- STCR based NPK application + ZnSO4 25 kg ha−1, N5- N2+ FYM (5 t ha−1), N6- N2+ FYM (5 t ha−1) + PSB (5 kg ha−1)+ Azotobactor 20 kg ha−1, N7- 75% RDN + FYM (5 t ha−1) + ZnSO4 25 kg ha−1, N8-75% RDN + FYM (5 t ha−1) + PSB (5 kg ha −1) + Azotobactor 20 kg ha−1 + ZnSO4 25 kg ha−1, N9- Organics Practices @ FYM (30 t ha−1)+PSB (5 kg ha−1) + Azotobactor 20 kg ha−1 + ZnSO4 25 kg ha−1, *NS- Non-significant, PERC_V = Percolation water volume, TWU_V= Total water use volume, WPIRRI= productivity of water in applied irrigation.

WPTCW, productivity of water needed in crop total water and WPETC = productivity of water in as evapo-transpiration only.
