A field experiment was conducted on a clay loam soil at Indian Institute of Rice Research (IIRR) formerly Directorate of Rice Research (DRR), Rajendranagar, Hyderabad, Telangana during the kharif seasons of 2015 and 2016 to study the “Assessment of production potential of rice with irrigation regimes and nitrogen management practices under different establishment methods”. The treatments consisted of three establishment methods Normal transplanting (NTP), Mechanized System of Rice Intensification (MSRI) and Drum seeding (DS) as main plot treatments, two irrigation regimes continuous flooding, Alternate wetting and drying at 5cm depletion as sub plot treatments and two nitrogen management practices (RDN - 100 % through inorganic and RDN - 75 % inorganic and 25 % organic) as sub-sub plot treatments summing upto 12 treatment combinations laid out in split-split plot design with three replications. Normal transplanting method required higher input energy. | Assessment of energetics of rice with irrigation and nitrogen management practices under different establishment methods
