Produtividade e qualidade da cultura do centeio (secale cere-ale l.) sob quatro sistemas de produção: "BDOKC" biodinâmico, orgânico, convencional agroquímico e controle (testemunha)

Abstract

Agricultural Science and technology constantly evolves in search for more productive alternatives with less environmental impacts. The present research work sought to verify the yeld and quality of the rye crop under different production systems of treat-ments. The production systems evaluated were Biodynamic, Conventional and Or-ganic, with a Control treatment and an additional Nil-Control. Biodynamic treatment stimulates the connection between the farmer and the land, using biodynamic prepa-rations. Conventional Agrochemical treatment is currently the best-known form of management, using large amounts of external inputs to achieve high yields. The Or-ganic treatment seeks better yields and quality of food without the use of agrochemi-cals. The experiment was designed with 6 blocks of replicates, for each treatment system. Three samples for Destructive Growth Analyses were taken, the first during the tillering period, the second during flowering and the last one during the ripening period, to obtain Fresh and Dry Weights and Dry Matter Percentage of plants and ears. Significant differences were found in the two first . However, we emphasize the productivity analysis performed after harvesting the same, seeking information about which treatment would bring better development to the crop in relation to grain pro-duction, but the production had no significant differences between the samples but from the analysis of the hectoliter weight of the samples, it was found that such results showed great similarity, this may have been caused due to not having adequate experimental harvesting equipment.
