Abstract

An experiment was carried out at research farm of Division of Agronomy, SKUAST-K, Wadura, Jammu and Kashmir, during the kharif seasons of the year 2021 and 2022 to appraise marked effect of different rice establishment methods and irrigations regimes. The experiment included rice establishment methods as main plot treatments (SRI: System of rice intensification; DSR: Direct seeded rice; TPR: Transplanted Rice) and different irrigation regimes as sub plot treatments (I1: Continuous submergence (flooding) upto 3cm depth; I2: Application of irrigation (24 litres m-2) 4 days after disappearance of ponded water throughout crop growth; I3: Application of irrigation (24 litres m-2) 4 days after disappearance of ponded water upto panicle initiation and then submergence upto dough stage; I4: Application of irrigation (24 litres m-2) 4 days after disappearance of ponded water upto flowering and then submergence upto dough stage; I5: Saturation throughout (1cm of standing water). Over TPR and DSR establishment methods, SRI showed significantly higher periodic Leaf Area Index, SPAD and PAR values. Amid different irrigation regimes, I1 showed significantly higher values for periodic LAI, SPAD and PAR in contrast to I2 and I4, nevertheless, was at par with I3 and I5. Lowest values for periodic LAI, SPAD and PAR were found under I2.
