Abstract:
A field experiment conducted to assess the influence of nitrogen (N) management practices through neem coated urea (NCU) on phosphorus (P), potassium (K) uptake and distribution in different plant parts (leaf, stem and panicle), grain yield and soil chemical properties of transplanted rice. The results indicated that application of NCU at 125% recommended dose of N (RDN) with 50:25:25 split schedule at basal (B), active tillering (AT) and panicle initiation (PI) stages resulted in higher P, K uptake and distribution to leaf, stem and panicle at harvest than the application of prilled urea at 100% RDN with the same split schedule (existing practice). Further, the increment in grain yield was 10.95% higher than the existing practice. The significantly higher available soil nitrogen (226 kg ha-1) was recorded with of NCU at 125% recommended dose of N (RDN) with 33.3:33.3:33.3 split schedule at B, AT and PI stages.
