Com o objetivo de avaliar o efeito de arranjos de plantas e da presenca de ervas daninhas na epoca de colheita e em outras caracteristicas agronomicas associadas a colheita do girassol cv. Contisol 711, conduziu-se este trabalho na regiao fisiografica da Depressa Central do Rio Grande do Sul, Rs, no ano agricola de 1987/88. O tratamento constaram de tres densidades de plantas (30, 50 e 70 mil plantas/ha), tres espacamentos entre linhas (0,4; 0,7 e 1,0 m), e de presenca e ausencia de ervas daninhas. Com o aumento de densidade de plantas e com a presenca de ervas daninhas houve a reducao da umidade de graos e de receptaculo de capitulo, assim como aceleracao da senescencia foliar, avaliada pelo indice de area foliar. Esses resultados evidenciaram que a elevacao da densidade de plantas dentro dos limites estudados, pode constituir metodo eficiente para antecipar a colheita do girassol sem reflexos negativos sobre outras caracteristicas a ela associadas. |

Forests function as carbon reservoirs since they act in its sequestration and storage, playing a fundamental role in global climate change mitigation. Payments for this kind of environmental service have emerged as an important means for combating deforestation. This study evaluated the potential of a Sedimentary Basin Humid Forest refuge in a Semiarid Brazilian region (Chapada do Araripe, southern Ceará state) to receive payments for environmental services (PES) for carbon (C) assimilation and storage. The biomass quantification was performed by the non-destructive method and the determination of the C content was carried out using a LECO carbon analyzer to correlate carbon production in different litter components with climate variables. The carbon, carbon increment and stored carbon values were obtained by information collected from a continuous forest inventory. The average carbon content of each litter component and the volume of wood stored in the forest indicated that the fragment has 27.78?t?ha?1 of carbon stored in its living biomass and an annual increment of 1.26?t?ha?1 year. The carbon sequestered annually totaled 3.99?t?ha?1 [carbon incorporated in the litter (2.73?t?ha?1) + average annual increment of carbon in the commercial volume (1.26 t ha?1)] indicating that the area sequesters an average of 102.02?t?ha?1 CO2e. Of the three studied compartments, only the leaves component showed a significant correlation with any climatic variable (rainfall). Based on amounts paid per ton of carbon sequestered, it is estimated that the area can earn ? 2583.79.ha?1 should it participate in a program of PES for carbon sequestration and storage. This value serves as an incentive for the conservation of biodiversity, promoting environmental benefits and financial advantages compared to other forms of land use.
