The intensive rice growth system reduces seed amount for sowing, increases plant yields and saves irrigation water
Main Article Content
Abstract
Research Station for three years and later at small-scale
producers´ areas belonging to a non-specialized system
(popular rice) as an agricultural extension. The study consisted
of determining the effect of seedling age, plant spacing and
seedling number per site on agricultural yield. Results showed
a seed amount reduction in the nursery, to the value of 5 kg.ha-1.year-1,
which represent between 35 and 40 % of that used in the
traditional transplanting system. In addition, agricultural yields
increased up to 2.0 t.ha-1; there was a greater tillering and root
system development per plant compared to the check control.
On the other hand, when crop irrigation was discontinued for
21 days, 3 300 m³.ha-1.year-1 of water were saved.
