CRISTO, Elizabeth; DIAZ, Sandra H; SHIRAISHI, M y DHANAPALA, M. P. Comparación entre LAS características de crecimiento de LAS variedades de arroz CON diferente origen. cultrop [online]. 2009, vol.30, n.3, pp. 23-27. ISSN 0258-5936.
At Tsukuba International Center (TBIC), belonging to Japan International Cooperation Agency (JICA), located at Ibaraki Prefecture, some growth and development parameters were studied, from March to September 2006, in four rice varieties: J-104, Bluebonnet-50, Suweon-294 and Nipponbare. During crop development since May 5, the following growth development parameters: stalk number, leaf number, plant height, fertilized tillers, agricultural yield (t.ha-1) and its components, as well as green color intensity were weekly evaluated and some differences were observed. J-104 variety showed the best behavior for green color intensity of leaves, panicle grain number, 100-grain weight and agricultural yield, whereas the best results were obtained by the Japanese variety, Nipponbare, for the other growth and development parameters.
