tailieunhanh - Physiological growth parameters of Rabi rice (Oryza sativa L.) under alternate wetting and drying irrigation with varied nitrogen levels

A field experiment was conducted during rabi 2016-17 and 2017-18 at Agricultural Research Institute Main Farm, Rajendranagar, Hyderabad, on a clay loam soil to study the effect of alternate wetting and drying irrigation on rabi rice under varied nitrogen levels. The experiment consisted of three irrigation regimes (recommended submergence of 2 to 5 cm water level as per crop growth stage, AWD irrigation of 5 cm when water level drops to 3cm in water tube, AWD irrigation of 5cm when water level drops to 5 cm in water tube) as main plot treatments and three nitrogen levels (120, 160 and 200 kg N ha-1 ) as sub plot treatments laid out in split plot design with three replications. Significant improvement in the physiological growth parameters was observed with recommended submergence of 2 to 5 cm water level as per crop growth stage which was on par with AWD irrigation of 5 cm when water level drops to 3cm in water tube. Among nitrogen levels, application of 200 kg N ha-1 resulted in higher physiological growth parameters of Rabi Rice which was on par with application of 160 kg N ha. | Physiological growth parameters of Rabi rice (Oryza sativa L.) under alternate wetting and drying irrigation with varied nitrogen levels
