RUIZ, M et al. Comportamiento de la variedad de arroz (Oryza sativa L.) INCA LP-4 sembrada en diferentes épocas del año. cultrop [online]. 2009, vol.30, n.1, pp.00-00. ISSN 0258-5936.

In 2005, the monthly behavior of the mid-cycle rice variety INCA LP-4 was studied on a Hydromorphic Nodular Gley Petropheric soil with a randomized block design at “Los Palacios” Rice Research Station. Thus, agricultural yield and other characters were evaluated, in order to know varietal response seeded at different times; the information recorded was processed by means of a Two-way Classification Variance analysis whereas differences between means were docimated according to Duncan´s Multiple Range test for p£0.05. The best behavior was observed in January and February sowings, when plants reached the characteristic height of a mid-cycle variety; agricultural yield and its components were the best as well as industrial quality, which is recommended to be seeded during these months.
