A field experiment was carried out to study the response of irrigation scheduling and split application of nitrogen on yield, grain quality parameters and soil microbial activities of direct–seeded rice (DSR) during the kharif season 2015 at New Delhi. The experiment was laid out in split plot design with 12 treatments combination of irrigation scheduling viz; 0 kPa, 10 kPa, 20 kPa and 40 kPa irrigation scheduling threshold was maintained between tillering to flowering stages in main plot and application of N @ 120 kg/ha as control (N0), half recommended dose of nitrogen (RDN) as basal + one-fourth RDN at week 2 + one-fourth RDN at week 5, and one-fourth RDN as basal + one-fourth RDN at week 2 + one-fourth RDN at week 5 + one-fourth RDN at week 9 after sowing in sub plot with three replications. The results bring to light that irrigation scheduling at 0 kPa recorded the highest yield, grain quality parameters and soil microbial activities. As regards of N application the yield, grain quality parameters and soil microbial activities were significantly influenced by split application of N. With increase in the number of splits application along with basal application found more effective over control.
