Abstract:
Field experiment was conducted at Soil and Water Management Research Institute, Kattuthottam, Thanjavur during kharif season (July - October) of 2018 to study the effect of crop establishment methods and irrigation scheduling on growth and yield of direct dry seeded rice. The experiment was laid out in split plot design with three replications. The treatments comprised of two different crop establishment methods viz., Raised bed with manual sowing (M1), Flat bed with manual sowing (M2) in main plots and six irrigation scheduling in sub plots viz., Irrigation on the day of disappearance of ponded water (I1), Irrigation at 1 day after disappearance of ponded water (I2), Irrigation on 3 days after disappearance of ponded water (I3), Irrigation on 5 days after disappearance of ponded water (I4), Irrigation on 7 days after disappearance of ponded water (I5), Irrigation on 9 days after disappearance of ponded water (I6).It was found that raised bed panting with manual sowing (M1) recorded significantly higher plant height, number of productive tillers m-2, number of grains panicle-1 than flat bed planting with manual sowing (M2). But, there was no significant yield (kg/ha) difference between the raised bed and flat bed planting methods. Among the different irrigation treatments, irrigation on the day of disappearance of ponded water recorded highest grain and straw yield.
