Título:  Carbon dioxide emissions in agricultural systems in the Brazilian savanna.

Conteúdo:  The objectives of this work were to evaluate the CO2 emission potential of an Oxisol under integrated crop-livestock and no-tillage systems in the Brasilian Savanna; and to analyze the impact of soil temperature and soil moisture as factors that regulate the seasonality and the emission of C-CO2 in these systems. Field-scale study was carried out at Fazenda Brejinho, in Pedro Afonso-TO, under Oxisol. The production systems studied were integrated crop-livestock and no-tillage under cropped with soybean and corn. The amount of carbon (C) released from the soil in the form of CO2 (C-CO2) was evaluated using cylindrical chambers installed in the field with a vial containing sodium hydroxide to collect CO2 released from the soil (soil emission) in an interval of 15 hours. Five evaluations were conducted over crops growing season, started in 01/26 through 06/16/2015. Data were tested to analysis of variance and the means were compared with Duncan test at 5%. The emission of C-CO2 differed between treatments in all evaluation periods. On average, the temperature ranged from 26.5 to 27.7 °C, the soil moisture ranged from 12.2 to 15.7% and the C-CO2 emission ranged from 87.4 to 119.9 mg m-2 h-1. Temperature, soil moisture and the production systems contributed to the emission and seasonality of carbon dioxide emissions. The integrated crop-livestock cropped with soybean/corn rotation was the system that had the lowest carbon dioxide emission.

Título:  Quality of platanes grown in consortium with tree species.

Conteúdo:  Abstract: The objective of this work was to evaluate the quality of plantain fruits, D'Angola, produced in consortium with tree species and in different planting densities. For this, the experiment was designed in strips with four silvibane arrangements, namely: plane tree (Musa spp. L.) with eucalyptus Urocam VM01 (Eucalyptus urophyla S.T. Blake x E. camaldulensis Dehnh.); plantain with casuarina (Casuarina equisetifolia L.); sycamore with white taxi (Tachigali vulgaris L.F. Gomes da Silva & H.C. Lima) and sycamore with acacia (Acacia mangium Willd.). In each strip, three plane tree planting densities were randomly distributed, being: 1,250, 833 and 625 plants hectare, constituting the secondary treatment. The single planting (monoculture) of sycamore cv. D'Angola, was used as a control at a spacing of 4.5 m x 2.0 m x 1.6 m (1,923 plants/hectare). The following physical and physicochemical aspects of the fruits were evaluated: bouquet mass, fruit mass, pulp mass, fruit length, fruit diameter, pulp diameter, pulp/peel ratio, pulp yield, pulp firmness, shell thickness, total soluble solids, total titratable acidity and TSS/TTA (ratio). It was concluded that the plantain produced in the silvibananeiro system has lower fruit mass and length when compared to the single crop. On the other hand, the fruits met the quality standard for commercialization, regardless of the tree species used in the system. The planting density had no effect on the quality of banana cv. D'Angola. | Re... Mostrar Tudo
