  1. Long-term effects of urea and green manure on rice yields and nitrogen balance por Ladha, J.K., Dawe, D., Ventura, T.S., Singh, U., Ventura, W., Watanabe, I.

    Publicado 2000
    “…Data from a 14‐yr double‐crop rice (Oryza sativa L.) experiment allowed comparison of the long‐term effects of N fertilizer from different sources (urea and in situ grown azolla [Azolla microphylla Kaulf.] and sesbania [Sesbania rostrata Bremek. and Oberm.]) on N balances, soil N pools (both total and available), and yields. …”

    Publicado 2000
    “…In transplanted flooded rice (Oryza sativa L.) culture in Asia, N fertilizer recovery efficiency (RE) estimates are usually greater with the difference method than with the 15N method. …”

  4. Influence of Deep Root Density on Root Pulling Resistance in Rice por Ekanayake, I.J., Garrity, D.P., O'Toole, J.C.

    Publicado 1986
    “…Rooting patterns play an important role in determining the degree of resistance of rice (Oryza sativa L.) cultivars to water stress. Root pulling resistance (RPR) has been suggested as a technique to evaluate genotypic differences in root growth in rice. …”

  6. Rice cycles between drought and well-watered-adapted phenotypes by changing lateral root formation por Bochmann, Helena, Klein, Marie, Henry, Amelia, Faßbender, Heike, De Ocampo, Marjorie, Kant, Josefine, Watt, Michelle

    Publicado 2025
    “…This study investigates the genetic variation in root-to-shoot growth in response to a wet–drought–wet cycle and aims to identify rice (Oryza sativa) lines differing in drought recovery, focusing on detailed root trait investigations. …”

  7. Enhancing farming system water productivity through alternative land use and water management in vertisol areas of Ethiopian BlueNile Basin (Abay) por Erkossa, Teklu, Haileslassie, Amare, MacAlister, C.

    Publicado 2014
    “…Early planting of wheat (Triticum spp.) on BBF instead of the traditional late planting on flat beds in drainable areas and rice (Oryza sativa) cultivation instead of the traditional extensive grazing or growing grass-pea (Lathyrus sativus) on the flat areas provide viable alternative cropping options. …”
