Jorge Acosta Presents Thesis Findings at First Workshop on the
System of Rice Intensification in Latin America SRI Workshop in Costa
Rica
Following completion
of his thesis at
the University of Cundinamarca in Colombia, Jorge Orlando Acosta Buitrago
(right), presented his findings at the First Workshop on the System
of Rice Intensification (SRI) in Latin America held October 30 -
November 1, 2011, at the EARTH University campus in Costa Rica. (See
PowerPoint presentation).Acosta's research for the ingenieria agrononica degree was undertaken at the Facultad de Ciencias Agropecuariasat of the University of Cundinamarca in Fusagasugá. His experiments, the first SRI research carried out in Colombia, were done in the municipality of Purification, Tolima, between July 2010 and August 2011. He evaluated the variety F733 under three types of management (organic SRI, and chemical SRI and mixed chemical/organic SRI) and compared them with the conventional direct seeding rice system. (See thesis for variables measured). The organic SRI treatment yielded 8 tons/ha, producing 15.8% more rice than the conventional system (6.91 tons/ha). SRI using chemical fertilizers and chemical/organic combination obtained a 5.99 and 6.97 ton/ha respectively. Despite 600% seed savings, returns for SRI treatments were negative with conventional rice pricing. However, returns were positive in the organic market. SRI assessments were recommended for a minimum of 2 years, as SRI yields often increase over time and are projected to produce postive returns in the second or third season in conventional markets.

SICA Trials Started in Colombia during 2009
Jorge Orlando Acosta
Buitrago, whose SRI research plot is shown at left, is studying at the
University of Cundinamarca in Colombia for a degree in agronomic engineering.
Acosta planted probably the first SICA field (2 hectares) in his country, and
is writing a thesis on his observations. The main difficulties that he has
encountered are in weed control. He is using a motorized weeder (right), and
this is giving only partial control. -
