Water use efficiency and rice yield under different water managements

Abstract

Abstract: Subtle plot experiment was conducted to study the growth and water use status of rice cultivated on waterlogged soil and upland soil mulched with plastic film, semi decomposed wheat straw and nothing in Nanjing Agricultural University. The results showed that 349 to 473 mm of water were required by rice cultivated on upland soil mulched with film, straw or nothing, and 732.5 mm of water was required on waterlogged soil. The water productive efficiencies for rice grain and biomass were between0.899 to 1.273, and 1.655 to 2.321 g穔g^-1, respectively in upland cultivation, while 0.766 and 1.459 g穔g^-1 in waterlogged cultivation. Rice cultivated on upland soil mulched with semi decomposed straw achieved 90% or more economic yield on waterlogged soil.
