This study evaluated the quality of Schinus terebinthifolia (Brazilian peppertree) fruits at different maturation stages to determine the best stage to harvest and sell the fruits. Fruits of the BAAr-05 genotype were analyzed at five maturation stages: green fruit; pinkish-green fruit; pinkish fruit; ?mature? red fruit; and ?overripe,? intense
red fruit. Physical (weight, size) and chemical (chemical components of the essential oil, assessed using HS-GSMS, and essential oil yield) characteristics of each stage were analyzed. The experimental design was completely randomized with three repetitions. Chromatography data were submitted to a multivariate analysis (chemometrics). The principal component analysis (PCA) showed distinct chemical profiles referring to each maturation stage and the following main molecules: α-pinene; β-myrcene; α-phellandrene; limonene; and δ-3-carene. For the BAAr-05 genotype, the uniform maturation stages clustered together, and the intermediary stages were further apart, demonstrating a transition characteristic of the fruits at stages pinkish-green fruit and pinkish fruit. The yield of each oil extracted from its fruiting stages was obtained by hydrodistillation in a Clevenger apparatus. The red fruits produced the highest yield of extracted essential oil (3.76%), suggesting that this is the best stage to harvest the fruits. The data from HS-GC-MS chromatography were adequate for the chemometric analyses of the principal components of the maturation stages. Thus, our findings can contribute with information to optimize the harvest time of aroeira fruits, suggesting that the fruits harvested in the maturation stage red fruit (fully mature, red fruits) are the best for essential oil yield.

Currently, one of the biggest challenges faced by organic no-tillage farming is weed control. Thus, the use of cropping practices that help in the control of weeds is extremely important. The objective of this study was to evaluate population density and level of weed infestation in an organic no-tillage corn cropping system under different soil covers. The experiment was conducted in a randomized block design with six repetitions and five treatments, consisting of three soil covers in an organic no-tillage system, and an organic and a conventional system, both without soil cover. The treatments with soil cover used a grass species represented by the black oat, a leguminous species represented by the white lupine, and intercropping between both species. Corn was sown with spacing of 1.0 m between rows and 0.20 m between plants, using the commercial hybrid AG 1051. Infestation in corn was evaluated at stages V5 and V10, and weed density was evaluated at stage V5. The use of black oat straw alone or intercropped with white lupine, in the organic no-tillage corn cropping system, reduced the percentage of weed infestation and absolute weed density. Management-intensive systems and systems without soil cover showed higher relative densities for species Oxalis spp., Galinsoga quadriradiata and Stachys arvensis. The species Cyperus rotundus showed the highest relative density on organic no-tillage corn cropping systems. Black oat straw in the organic no-tillage cropping system limited the productive potential of corn.
Atualmente, um dos maiores entraves do sistema plantio direto orgânico é o controle de plantas daninhas. Desse modo, o uso de práticas culturais que auxiliem no controle dessas plantas torna-se de extrema relevância. Objetivou-se avaliar a densidade populacional e o nível de infestação de plantas daninhas no plantio direto orgânico de milho-verde sob diferentes coberturas de solo. O experimento foi conduzido no delineamento de blocos casualizados, com seis repetições e cinco tratamentos, constituídos por três coberturas de solo no sistema plantio direto orgânico e dois sistemas sem cobertura, sendo um orgânico e um convencional. Para os tratamentos com cobertura de solo foi utilizada uma espécie gramínea representada pela aveia-preta e uma espécie leguminosa representada pelo tremoço-branco, bem como o consórcio com as ambas espécies. A semeadura do milho para produção de espigas verdes foi feita no espaçamento de 1,0 m entre linhas e 0,20 m entre plantas, utilizando o híbrido comercial AG 1051. Foram realizadas avaliações de infestação nos estádios V5 e V10 do milho e de densidade de plantas daninhas no estádio V5. O uso de palha de aveia-preta solteira ou em consórcio com tremoço-branco, no sistema plantio direto orgânico de milho-verde, proporcionou redução do percentual de infestação e densidade absoluta de plantas daninhas. Os sistemas com manejo intensivo e sem cobertura de solo apresentaram maior densidade relativa das espécies Oxalis spp., Galinsoga quadriradiata e Stachys arvensis.
