Polymer coated urea (PCU) was evaluated for its efficiency under two rice establishment methods [transplanting method (TP) and direct-seeded rice (DSR)] during two crop seasons (rabi, dry season and kharif, wet season). The results indicated that split application of PCU @ 75 and 100% recommended dose of nitrogen (RDN) were at par and resulted in significantly higher yields (46 and 49%) than normal urea in splits, respectively, during rabi 2015–2016 under transplanting method. During kharif-2016 under transplanting method, grain yield was maximum with 100% RDN from PCU single dose (5.13 t ha⁻¹) which was on par to 100% PCU in 3 splits (4.62 t ha⁻¹) and 75% PCU (4.80 t ha⁻¹) as a basal dose. In DSR, significantly higher grain yield was recorded in 100% RDN supplied through PCU as basal dose (6.16 t ha⁻¹). The maximum nitrogen use efficiency indices were observed in 75% PCU (split) followed by 100% PCU (Split) in rabi-2015–2016 but in the case of kharif-2016, basal application of 100% PCU found to be superior followed by 75% PCU. Thus, PCU proved its efficiency by saving 25% of N in transplanted rice in both wet and dry seasons and by considerable labour saving due to single basal application in case of transplanting as well as DSR in the wet season.

聚合物涂覆的尿素（PCU）的混合物在两个水稻建立的方法在两个作物季节（[移植方法（TP）和直接播种的水稻（DSR）]评价其效率拉比，旱季和秋收，雨季）。结果表明，在2015-2016 年移栽期间，分批施用 PCU @ 75 和 100% 推荐剂量的氮 (RDN) 处于同等水平，并且分批施用的产量分别显着高于正常尿素的产量（46% 和 49%）方法。在夏播下移栽方法-2016，谷粒产量是用100％的最大RDN从PCU单剂量（5.13吨公顷^-1），它是持平至100％PCU在3个分割（4.62吨公顷^-1）和75％PCU（ 4.80 吨公顷^-1 ) 作为基础剂量。在 DSR 中，通过 PCU 提供的 100% RDN 作为基础剂量（6.16 t ha ^-1）记录了显着更高的谷物产量。最大的氮利用效率指数在 75% PCU（分裂）和 100% PCU（分裂）的rabi -2015-2016中观察到，但在 kharif -2016的情况下，发现 100% PCU 的基础应用更好，其次是75% PCU。因此，PCU 通过在旱季和旱季移栽水稻中节省 25% 的 N 以及在移栽情况下单次基施以及在雨季 DSR 的情况下节省大量劳动力来证明其效率。
