Levantamento da produção de sementes de soja e trigo no estado do Paraná

Abstract

The production of seeds of soybean and wheat in the State of Paraná is well significant in the national context. The accompaniment of the State seed production at crop seasons 93/94 to 02/03 was carried by the Division of the Production of Seeds and Seedlings of the Department of Fiscalization of State Office of Agriculture and Supplying - Secretaria de Estado da Agricultura e do Abastecimento – SEAB, the state certification and fiscalization entity. The objective of this work was to supply informations to the productive sector of seeds analyzing the behavior, evolution and trends in important phases of the process of production of seeds of these two important crops cultivated in Paraná. In this work, were used the referring historical data of enrolled area, approved area, gross production received, approved production and commercialized production of the crop seasons of 93/94 to 02/03. The data were divided in two categories: certification, that encloses the classes registered, certified and fiscalized. Due the relevance of the soybeans, the maturation cycle also was object of study of this work. The analysis of the data and the interpretation of the results allowed to conclude that: the program of certification trend to grow and the fiscalized seed to fall, for wheat and soybean; about maturation cycles precocius and semiprecocius in the soybean trend up its demand of seeds in the program; the fields approval is bigger in the certification in relation to fiscalized class and bigger in soybean in relation to wheat; the productivity of certification is bigger than the fiscalized class in soybean and wheat, and both are less than the grain productivity in soybean; the losses in the conditioning and quality control are around 40% in soybean; and high levels of seed surplus indicate lack of interaction between planning, production and commercialization sector.
