Relación del crecimiento y rendimiento de la variedad INCA LP-5 sometida a los principios básicos del sistema intensivo del cultivo del arroz (SICA)
Main Article Content
Abstract
Rice Research Station, Pinar del Rio, where the variety
INCA LP-5 was planted on a Ferruginous Nodular Gley
Hydromorphic soil in May, 2003, with the aim of analyzing its
growth and yield, following the basic principles of the Intensive
Rice Cultivation System (SICA) under two different soil fertility
conditions. A randomized block design with two treatments
and four replicates was used, at a plant spacing of 0.30 x 0.30 m,
by placing a single plant per site 13 days after rice germination.
Growth variables were evaluated 50 days after transplanting
and seven samplings were performed at different intervals of
50 to 113. Results indicate that the variables studied affected
crop yield under these conditions, the most associated one
being leaf area length (DAF) and the Maximum Growth Rate
Point of Dry Weight (PMVC); therefore, a deeper study is
recommended to attain more information to improve this variety
management with such a new production approach in those
areas devoted to obtain seed and popularization.
