A study on different tillages to find a sustainable rice production
Main Article Content
Abstract
development, causes salinization and declines yields after three
consecutive harvests. Thus, holding back such effects is
strategic; the special agronomic rice management inexorably
damages its agronomic qualities. Outlining a possible solution
to the problem, the present paper summarizes the main results
of a sustainable management in the rice-growing areas from
�??Los Palacios�?� Rice Experimental Station, where 31 alternatives
were tested in seven crop rotation systems, besides a survey
performed in Caribe farm from �??Los Palacios�?� agro-industrial
rice complex. It was proved that rice monoculture impoverishes
soil physical and chemical fertility whereas crop rotation allows
recovering lost fertility and achieving stable and sustainable
productions. Also, the work shows it is possible to establish a
sustainable rice-growing area.
