Effect of crop establishment and tillage management (CETM) (A) and P-fertilization practices (B) on NDVI, SPAD at flowering stage of maize and wheat under MWCS. The vertical bars represent LSD0.05 values. M1, flat bed–conventional tillage (FBCT) both in maize and wheat; M2, raised bed–CT (RBCT) in maize and RB–zero tillage (RBZT) in wheat; M3, FBZT both in maize and wheat; M4, permanent raised bed–ZT (PRBZT) both in maize and wheat. S1-P100, 100% P as basal; S2-P50 + 2FSP, 50% P as basal (P50) + 2 foliar sprays of phosphorus (2FSP) as DAP (2%) at knee-high stage (KHS) and pre-tasseling stage (PTS) in maize and at tillering stage (TS) and pre-flowering stage (PFS) in wheat; S3-P50 + PSB + AM-fungi (AMF); S4-P50 + PSB + AMF + 2 FSP at KHS and PTS in maize and at TS and PFS in wheat; S5-P0, 100% N and K with no-P (P0) as control.
