Performance of maize hybrids with high and medium yield potential

By Carlos Eduardo Weber dos SANTOS

Abstract

O presente estudo analisou o posicionamento dos h??bridos de milho da empresa de sementes Biomatrix sendo analisados os caracteres agron??micos, ou seja, respectivamente sua capacidade produtiva. Foram analisadas as seguintes cidades: Carazinho, RS, Coxilha, RS, Ponta Grossa, PR e Xanxer??, SC. Os dados obtidos foram submetidos ?? an??lise de vari??ncia (ANAVA) utilizando-se os n??veis de signific??ncia de 5% para o teste F. Empregou-se o teste de compara????o m??ltipla de Tukey, para avaliar as diferen??as entre as m??dias dos tratamentos, quando o valor de F fosse significativo. As an??lises estat??sticas foram realizadas com o pacote estat??stico CoStat. Os resultados obtidos n??o diferiram estatisticamente, pois o clima se portou de forma heterogenia no per??odo de execu????o do trabalho, contudo os h??bridos BMX828 e BMX817 do alto e m??dio potencial produtivo respectivamente expressaram relativo rendimento maior a testemunha, permanecendo sempre no grupo superior em produtividade.This study analyzed the positioning of hybrid corn seed company Biomatrix being analyzed for agronomic characteristics, ie its production capacity respectively. We analyzed the following cities: Carazinho, RS, Coxilha, RS, Ponta Grossa, PR and Xanxer??, SC. Data were subjected to analysis of variance (ANAVA) using the significance levels of 5% for the test F. We used the multiple comparison test of Tukey, to assess differences between treatment means when the F value was significant. Statistical analyzes were performed using the statistical package CoStat. The results were not statistically different, because the weather behaved so heterogeneous in the duration of the work, however hybrids and BMX828 BMX817 of high and medium potential yield respectively, expressed relative yield greater witness, remaining always in the top group in productivity
