Resíduos agrícolas e argila expandida no cultivo da orquídea Oncidium baueri Lindl.

For orchid cultivation in containers is essential to select the right substrate, since this will influence the quality of the final product, it serve as a support for the root system of the plants. This study aimed to evaluate different agricultural residues and expanded clay in Oncidium baueri Lindl. orchid cultivation. The plants were subjected to treatments: pinus husk + carbonized rice husk, pinus husk + coffee husk, pinus husk + fibered coconut, pecan nut husk, expanded clay, fibered coconut, coffee husk, carbonized rice husk, pinus husk. After eleven months of the experiment, the following variables were evaluated: plant height; largest pseudo-bulb diameter; number of buds; shoot fresh dry matter; the longest root length; number of roots; root fresh matter; root dry matter; and electric conductivity; pH and water retention capacity of the substrates. Except the expanded clay, the other substrates showed satisfactory results in one or more traits. Standing out among these substrates pinus husk + coffee husk and pine bark + fibered coconut, which favored the most vegetative and root characteristic of the orchid. The mixture of pinus husk + coffee husk and pinus husk + fibered coconut, provided the best results in vegetative and root growth of the orchid Oncidium baueri and the expanded clay did not show favorable results in the cultivation of this species.

Desempenho produtivo e econômico do consórcio de cafeeiro arábica e nogueira-macadâmia

The objective of this work was to evaluate the productive and economic performance of Arabica coffee and macadamia nut intercropping, under rainfed and drip-irrigation conditions, as well as the financial viability of treatments in three coffee price scenarios. A completely randomized design was used, with six treatments (rainfed sole coffee, irrigated sole coffee, rainfed coffee-macadamia nut intercropping, irrigated coffee-macadamia nut intercropping, rainfed sole macadamia nut, and irrigated sole macadamia nut) and ten replicates. The productivity, the area equivalency index, and the economic outcomes of the treatments were evaluated in three coffee price scenarios. Drip irrigation and intercropping increased coffee and macadamia nut yields, in comparison to rainfed monocultures, and generally promoted the same productivity as the coffee irrigated monocultures, as well as higher productivity than the macadamia nut irrigated monocultures. The combined use of intercropping and drip irrigation promotes land-use efficiency 5-fold greater than the averages of rainfed monocultures. Irrigated intercropping promotes higher profitability and faster return on investment, making it a viable alternative, especially in periods of lower coffee prices.

Efeito da fermentação fúngica no teor de compostos fenólicos em casca de café robusta

Coffee husk is an abundant by-product generated by the coffee industry and it can be used for the production of-value-added phenolic compounds. Currently, this residue has no commercial use due to the presence of anti-nutritional compounds and it is returned to the soil or burned. The aim of this study was to evaluate the content of phenolic compounds in Robusta coffee husk, the adequacy of this residue as substrate for fermentation processes, as well as evaluating the influence of fungal solid state fermentation to obtain phenolic compounds from this residue. In the present study, the use of different solvents for the extraction of polyphenols was evaluated and the content was found to be in the range of 96.9-159.5 mg of galic acid (GA).g(-1) substrate, depending on the solvent used. The best solvent was acetone, therefore it was selected for extraction. Studies were carried out to evaluate the effect of solid-state fermentation in the release of phenolic compounds, using the filamentous fungi Penicillium purpurogenum. The total phenolic content increased from 159.5 up to 243.2 mg GA.g(-1) substrate as a result the solid-state fermentation.

Growth and reproduction of earthworm in organic waste mixtures and effects on chemical and microbial properties of vermicompost

There is a large demand for organic fertilizers in organic agriculture, but few options for different wastes have been studied. The aim of the present work was to evaluate the biological responses of earthworms Eisenia andrei Bouche in wastes composed of cattle manure, peanut husk and spent coffee grounds, as well as to analyze the effect of earthworms on the microbial density and chemical properties of the vermicompost. Four treatments were employed, H1: cattle manure (100%), H2: cattle manure (75%) + peanut husk (25%), H3: cattle manure (75%) + spent coffee grounds (25%), H4: cattle manure (50%) + spent coffee ground (25%) + peanut husk (25%), with six replicates in a completely randomized design. The addition of spent coffee grounds to the manure increased the total biomass and indicated a rising trend in the production of cocoons, while the peanut husk apparently did not affect these variables. The CFU of bacteria and fungi were affected by the treatments at the beginning and end of the experiment and by the earthworms during the waste transformation. The evaluated organic waste mixtures differently affected the growth and reproduction of earthworms and chemical and biological properties of humus.

Prevalência, distribuição espacial e fatores de risco para cisticercose bovina no estado de São Paulo

This study aimed to determine the prevalence and geographical distribution as well as the factors and areas of risk associated with bovine cysticercosis in the State of Sao Paulo. 34.443 cattle, males and females with ages from 18 to 60 months were inspected. The animals were from 97 cities in the state of Sao Paulo and identified and slaughtered in the period October 2010 to August 2011, in a refrigerator located in Ipua - SP, under the supervision of SIF 1387. The state of Sao Paulo was divided into regional centers, and the data of the municipalities belonging to its core, were grouped according to the Department of Agriculture and Food Supply of Sao Paulo, totaling 13 cores studied. Based on these results, we can conclude that of the 97 cities analyzed, cattle were found positive for the disease in 86. The average prevalence of bovine cysticercosis in the state of Sao Paulo was 4.80 %, while the core inflation Franca and Barretos were the ones with the highest number of cases illness during the analysis period. Moreover, the largest number of cases in these core coincided with the lowest human development index covering education, with the largest acreage of coffee (core Franca) and also as the largest area of cane sugar grown (core Barretos) in these locations, which in turn may indicate that the presence of labor, temporary labor in rural areas, combined with socioeconomic/cultural factors might contribute to the spread and establishment of bovine cysticercosis in these areas.
