Abstract:

A field investigation was made during the late samba (September - January) season of 2019-20 at Tamil Nadu Agricultural University, Coimbatore to study the performance of puddled transplanted rice due to delayed basal and varied time of nitrogen and potassium application .The experiment was laid out in Randomized Complete Block Design with three replications. The treatment comprised of T1 - Control (Basal application of N and K before transplanting with three top dressings), T2 - N and K application on 3 Days After Transplanting (DAT) with 3 top dressings, T3 - N and K application on 7 DAT with  3 top dressings, T4 - N and K application on 10 DAT with 3 top dressings, T5 - N and K application on 15 DAT with 3 top dressings,T6 - N and K application on 7 DAT with  2 top dressings, T7 - N and K application on 10 DAT with 2 top dressings and T8 - N and K application on 15 DAT with 2 top dressings. The result showed that delayed basal application of N and K at 15 DAT with three top dressings (T5) recorded significantly higher plant height, LAI, drymatter production, panicle length, panicle weight, number of grains/panicle, filled grains /panicle led more grain (6346 kg/ha) and straw (8800 kg/ha) yields than others; but with delayed basal N and K application at 15 DAT with two top dressings, 10 DAT with three top dressings /two top dressings (T8, T4 and T7).
