Produtividade e aspectos agronômicos de tomateiros conduzidos em sistema orgânico e convencional
Abstract
The objective of this work was to compare the agronomic aspects and production
costs of two Italian tomato production systems cv BS II 0011 staked in a greenhouse,
one in the Organic Production System (SMO) and one under the Conventional
Management System (SMC) in winter cultivation in the Municipality Guaiçara / SP.
The SMC and SMO of the different crops were characterized, addressing the
agronomic and economic aspects, (soil preparation, planting, management, cultural
treatments, pest control, diseases, spontaneous plants, productivity and height, and
production costs). The agronomic variables analyzed were: plant height, weekly
production and accumulated tomato production. The three variables showed
significant results, according to the Tukey test, all favorable to SMC, in the same way
as to the results of production costs and financial return. The survey of production
costs showed similar values for both systems. Thus, to result in the same net profit,
the sale value of organic tomatoes should increase proportionally to the reduction in
production, that is, 50% higher. However, the experiment is in the first year of
organic, indicating a tendency to reduce input costs, due to working in a balanced
system, reducing production costs.
