CARACTERÍSTICAS AGRONÔMICAS DE GENÓTIPOS DE GIRASSOL CULTIVADOS EM SÃO LUÍS - MA

Sunflower crop is a good option of income generation because of its grains commercialization and oil extration. The lack of knowledge about performance of genotypes at local conditions is one of the problems to the installation of this crop in the Maranhão State The objective of this work was to evaluate sunflower genotypes and to verify its productive potential in the Maranhão State. The aquenio yield, oil content, oil yield, initial flowering, physiological maturation and height of plants had been evaluated. It was observed that genotypes showed a low average aquenio yield (348 kg/ha), but their average oil content was sactisfatory. ACA 884, Helio 358 and Agrobel 962 had the best results for all of agronomical characteristics evaluated

SANIDADE DE SEMENTES DE GIRASSOL PROVENIENTES DE TRÊS MUNICÍPIOS DO ESTADO DO MARANHÃO

The increasing importance of sunflower leads to studies on seed pathogen, to guarantee crop sanity and to provide identification of pathogens in new areas. Genotypes seeds lots produced in Embrapa Soja assays carried out in tree cities of the State of Maranhão, Brazil (Balsas, São Luís and Timon) were analyzed, with the objective of evaluating sanitary quality of sunflower seeds. Sanitary analysis was performed by blotter test method and identification of fungi genera was based on morphological features. The occurrence of Fusarium sp., Alternaria spp., Curvularia sp., Dreschelera sp., Aspergillus sp., Penicillium sp., Phoma sp., Trichoderma sp., Botrytis sp., Rhizoctonia sp., Rhizopus sp., Colletotrichum sp., Chaetomium sp., Cladosporium sp. and Sclerotinia sclerotiorum was observed in seeds of sunflower, with variable incidences
