Soyben seed peoduction and consitioning at coamo - Santo Antonio unity, Mangueirinha -PR

O presente estudo tem como objetivo analisar a efici??ncia da produ????o e do beneficiamento de semente de soja na COAMO, unidade do Santo Ant??nio, munic??pio de Mangueirinha Paran??, no per??odo que compreende as safras 2003/2004 a 2007/2008, Para isso, foram analisadas as s??ries hist??ricas e informa????es referentes ?? ??rea inscrita, ??rea aprovada, previs??o de recebimento, recebimento, beneficiamento de sementes recebidas, sementes analisadas pelo laborat??rio, a porcentagem de sementes reprovadas em fun????o dos fatores de reprova????o: germina????o, pureza f??sica e pureza varietal, sementes de soja aprovadas conforme cinco intervalos de germina????o em porcentagem, a porcentagem de participa????o das cultivares utilizada por safra quanto ao grupo de matura????o, e a porcentagem de participa????o das empresas obtentoras por safra de produ????o de sementes. Os resultados mostram alta efici??ncia na porcentagem de aprova????o da ??rea inscrita, com m??dia do per??odo de 97,9% de ??rea aprovada. A efici??ncia do recebimento expressa em porcentagem recebida, obteve resultado m??dio de 100,4%, no beneficiamento o ??ndice de rendimento m??dio do per??odo foi de 75,9%. Em rela????o as sementes analisadas pelo laborat??rio o ??ndice de aprova????o foi de 90,5%, a porcentagem de sementes reprovadas em fun????o dos fatores de reprova????o apontou que 7,1% da semente produzida e analisada pelo laborat??rio ?? reprovada por germina????o e 2,4% por pureza varietal. Em rela????o as sementes de soja aprovadas, quanto aos intervalos de germina????o tem-se que 33,6% da semente produzida ?? aprovada com porcentagem de germina????o acima de 90%, 37,8% est??o entre 89 e 85 % , apenas 21,5% entre 84 e 80%, e abaixo de 80% est??o 7,1%, os quais comp??em os fatores de reprova????o. Em rela????o ??s cultivares utilizadas para multiplica????o de sementes quanto ao grupo de matura????o, observa-se um aumento por materiais de ciclo precoce no per??odo estudado. Em rela????o a porcentagem de participa????o das empresas obtentoras tem-se diminui????o de participa????o das empresas Coodetec e Embrapa, e um aumento da Syngenta bem como o aparecimento de outras no cen??rio.The objective of the present study was to analyze the efficiency of soybean seed production and conditioning at the COAMO, unit of the Santo Antonio, city of Mangueirinha Paran?? state, Brazil during a period of five years (2003/2004 to 2007/2008). The efficiency of the company was detached in all phases of the process of soybean seed production. The historical series and referring information to the enrolled area was analyzed according to: approved area, forecast of receiving, act of receiving, improvement of received seeds, seeds analyzed by the laboratory, the percentage of seeds refused in function of the reprobation factors: germination, physical purity and varietal purity, seeds approved as five intervals of germination percentage, the percentage of participation by group of maturation, and the percentage of participation of the obtainors companies. The results show high efficiency in the percentage of approval of the enrolled area, with average of 97,9 % of approval in the period. The efficiency of the receiving act in percentage resulted in an average of 100,4%; the improvement of conditioning in the period was 75,9%; in relation to seeds analyzed by the laboratory the approval index was of 90,5%; the percentage of seeds disapproved in function of the reprobation factors pointed out that 7.1% of the seed produced and analyzed by the laboratory are disapproved by germination and 2.4% are for varietal purity; in relation to germination 33.6% of the produced seed were approved with percentage of germination above 90%, 37.8% were between 89 and 85% of germination, only 21.5% were between 84 and 80% of germination and below 80% of germination were 7.1%, which compose the reprobation factors. It was observed an increase for materials of precocious cycle in the studied period, In relation to the percentage of participation of the obtainors companies, there was a reduction of participation of companies Coodetec and Embrapa and an increase of the Syngenta and appearance of others in the scene
