Irrigation of rice using groundwater is considered one of the main contributors
to north-west India's declining water level. The present study hypothesizes that
zero-till direct seeding of rice (ZTDSR) with the optimum irrigation schedule
may reduce irrigation compared to puddled transplanted rice (PTR). Crop
growth stage-dependent predefined soil matric potential (SMP), that is, 15,

30 and 45 kPa based irrigation schedules either during the entire growing
period or their combinations during the vegetative phase in ZTDSR, were com pared with PTR for two consecutive seasons. The results showed that irrigation
in ZTDSR at lower SMP at any growth stage caused adverse effects on yield.
Irrigation at 15 kPa during the entire crop season with straw mulch was
found to be the best schedule for ZTDSR. ZTDSR with 15 kPa irrigation,
however, saved 36.2 cm of water and recorded higher water productivity but
produced 20% less grain yield over the prevailing PTR. A higher groundwater
system loss (GWSL) was found in the PTR (29.2 cm) than in the best ZTDSR
(23.6 cm) schedule, which indicates better groundwater management in the
ZTDSR than in the PTR. Hence, the ZTDSR has the potential to save irrigation,
achieve higher water productivity and manage the depletion of groundwater
resources in rice–wheat dominant north-west India.
