  1. Genetics and genomics of African Rice (Oryza glaberrima Steud) domestication por Wambugu, P.W., Ndjiondjop, M.N., Henry, R.

    Publicado 2021
    “…African rice (Oryza glaberrima Steud) is one of the two independently domesticated rice species, the other one being Asian rice (Oryza sativa L.). Despite major progress being made in understanding the evolutionary and domestication history of African rice, key outstanding issues remain controversial. …”

  2. Seed Germination Rate and Associated Characters in Rice por Krishnasamy, V., Seshu, D.V.

    Publicado 1989
    “…Rapid seed germination will facilitate quick plant stand establishment in direct sown rice (Oryza sativa L.) culture. Sixty‐eight rice cultivars were grown in the field and in the phytotron, and the harvested seed evaluated for germination rate. …”

  3. Seedling Stage Drought Response in Rice por O'Toole, J.C., Aquino, R.S., Alluri, K.

    Publicado 1978
    “…Drought‐related problems of crop establishment occur in many of the world's rainfed rice (Oryza sativa L.) growing areas. Little effort has been made to breed improved cultivars for these chronically drought‐prone areas. …”

  4. Automatic Feedback Control to Maintain Constant Soil Moisture Tension in the Study of Drought Tolerance in Rice por Alvarez, E.I., De Datta, S.K.

    Publicado 1977
    “…Response to the sensors' demand for water is rapid.We have successfully used this setup to compare relative drought tolerance of rice (Oryza sativa L.) varieties and breeding lines. Another use of this setup might be to measure evapotranspiration (ET) almost instantaneously; the technique might be useful in some soil‐plant‐atmosphere‐water relationship studies.…”

  7. Breakdown of plant residues with contrasting chemical compositions under humid tropical conditions: effects of earthworms and millipedes por Tian, G., Brussaard, Lijbert, Kang, B.T.

    Publicado 1995
    “…The effects of tropical earthworms (Eudrilus eugeniae) and millipedes (Spirostreptidae) on the breakdown of plant residues [Acioa (presently, Dactyladenia) barteri, Gliricidia sepium and Leucaena leucocephala prunings, maize (Zea mays) stover and rice (Oryza sativa) straw], with contrating chemical compositions, were studied in the field under humid tropical circumstances. …”

  8. Mulching effect of plant residues of chemically contrasting compositions on soil organic matter content and cation exchange capacity por Tian, G., Brussaard, Lijbert

    Publicado 1997
    “…Effects of five types of plant residues [Acioa, presently Dactyladenia barteri, Gliricidia sepium, and Leucaena lecocephala prunings, maize (Zea mays) stover and rice (Oryza sativa) straw] applied as mulch on soil organic matter (SOM) content and effective cation exchange capacity (ECEC) were studied on an Alfisol in the humid tropics. …”
