Abstract:

A field experiment was conducted on sandy clay soil at Agricultural College farm, PJTSAU, Rajendranagar, Hyderabad during kharif, 2016 in a split plot design with three replications. The treatments comprised of three irrigation regimes (irrigation of 5 cm when water level falls below 5 cm from soil surface in field water tube, irrigation of 5 cm, at one day after disappearance of water on the surface of the soil and recommended submergence of 2-5 cm water level as per crop stage) as main treatments and four rice varieties (Telangana sona, Kunnaram sannalu, Bathukamma and Sheethal) as sub plots treatments. The data recorded indicated that recommended submergence of 2-5 cm water level as per crop stage recorded higher dry matter and N, P and K uptake over AWDI of 5 cm when water falls below 5 cm from soil surface in field water tube and was on par with AWDI of 5 cm at one DADSW. Bathukamma produced higher dry matter and N P K uptake compared to Kunaram Sannalu, Sheethal and Telangana Sona. Based on the results it can be concluded that Bathukamma recorded higher dry matter and N, P and K uptake under recommended submergence of 2-5 cm water level as per crop stage.
