“…The interception of solar radiation by weeds, preventing the passage of light into the crop, depends on the composition, density, and distribution of these plants (Pitelli, 2014). Marcolini et al (2010) verified that the beet crop was very sensitive to the interference imposed by A. viridis plants, showing a significant reduction in leaf area, number of leaves, dry mass of leaves, mean root diameter, and fresh mass of roots even at low densities of weed populations.…”

“…Amaranthus is one of the major genera of weeds infesting peppers in Mexico and Canada (Amador-Ramirez, 2002;Robinson et al, 2008). It is also one of the most important weeds for various bean cropping areas (Barroso et al, 2012) and vegetable cultivation sites (Marcolini et al, 2010). Barroso et al (2012), in studies of inter-specific competition between beans and A. viridis, reported that the presence of weed decreased yield by 26%, negatively affecting the crop.…”

“…Knowledge of weed interference on crops is important in management decision making. The degree of weed interference on crops can be influenced by factors related to the weed community and the crop itself, such as the species present, the distribution, and the density (Barroso et al, 2012;Marcolini et al, 2010).…”

Competition interferes with the growth and development of plants, whether of the same species or not. The aim of this work is to evaluate the intra-specific interference of slender amaranth plants (Amaranthus viridis) at different densities and distances, and in an inter-specific interaction with red pepper (Capsicum baccatum var. pendulum). The experiment was conducted in four replications and in a randomized complete block design using a factorial scheme of 2x4 + 2 controls, which represent two distances (5 and 10 cm) between the weeds and pepper (transplanted in the center of the box) and 4 densities of slender amaranth (3, 6, 9, and 12 plants m-2). Cement-asbestos boxes with a capacity of 90 L were filled with clayey soils (Red Dark Latosol). The pepper seedlings were transferred to the boxes after having three fully expanded leaves, whereas the slender amaranth seedlings were transplanted when they were 5 cm in height. Growth and yield characteristics of the crop and weeds were evaluated. As a result, it was observed that as the density increased, both species suffered more damage; the red pepper showed etiolation and reduced production, and the weeds showed a reduction in growth parameters. The distance between the plants did not interfere with their intra-and inter-specific coexistence.

“…A beterraba (Beta vulgaris L.), importante hortaliça cultivada no Brasil, teve sua produção aumentada nos últimos anos principalmente em função da comercialização de seus produtos minimamente processados. Dentre seus vários componentes de interesse nutricional pode-se destacar a presença de vitaminas A, B1, B2, B5 e C além de minerais como cálcio, ferro, potássio, sódio e zinco (MARCOLINI et al, 2010). Dentre as regiões produtoras de beterraba do Brasil, Revista Brasileira de Tecnologia Agroindustrial destacam-se os Estados de São Paulo, Minas Gerais e Rio Grande do Sul, que juntos somam 42 % da produção nacional desta hortaliça tuberosa.…”

Resumo No processamento da cenoura e beterraba as folhas são descartadas, ainda que tenham boas propriedades nutricionais. O farelo de trigo é um subproduto gerado na moagem do trigo e apresenta altos teores de fibras e proteínas. Dentro deste contexto, o objetivo deste trabalho foi desenvolver biscoitos do tipo cookie utilizando farelo de trigo (FT) e farinha das folhas de cenoura (FFC) e de folhas de beterraba (FFB) em diferentes proporções, avaliando-se a aceitação e intenção de compra dos biscoitos. Fez-se um planejamento experimental de mistura do tipo Simplex Centróide resultando em sete diferentes formulações. Os biscoitos possuíam uma formulação base variando os teores de FT, FFC e FFB. Uma análise sensorial dos biscoitos foi realizada com 60 provadores não treinados considerando-se os parâmetros sabor, textura, avaliação global e intenção de compra. Os resultados foram satisfatórios para todas as formulações. Análises físicoquímicas das duas amostras com maior aceitabilidade revelou biscoitos com altos teores de fibras (22,39 e 11,34 g 100 g-1) e fonte de proteínas (8,22 e 9,10g 100 g-1). Visto que os biscoitos apresentam propriedades nutricionais desejadas e índices de intenção de compra (73,33 e 50,00 %) a possibilidade do desenvolvimento de biscoitos do tipo cookie utilizando os subprodutos agroindustriais foi confirmada. Palavras-chave: folha de cenoura; folha de beterraba; farelo de trigo. 1 Introdução Nos últimos anos, devido à ampliação das áreas agrícolas bem como dos avanços da biotecnologia, houve importante aumento das práticas agroindustriais aumentando o número de produtos do setor (CONAB, 2012; CARRER et al., 2010). Dados do IBGE (2011) mostram que o crescimento da agricultura brasileira chegou a 4,7 % em 2010 e, como consequência, na mesma proporção cresceu a produção de subprodutos agroindustriais, com estimativas de cerca de 250 milhões de toneladas ao ano. Além da crescente produção agrícola, produtos que antes eram comercializados in natura estão sendo transformados, intensificando a geração de resíduos (PELIZER et al., 2007).

Salinity is one of the major obstacles of modern agriculture, especially in the semi-arid regions, since these have high rates of evaporation and water sources with high salt terrors. Thus, the present study aimed to investigate the attenuating effects of bovine biofertilizer and biological fertilizer under irrigation with saline waters on the morphological behavior of beetroots (Beta vulgaris L.). The design was randomized blocks in a factorial scheme 4 × 2 + 1, referring to the electrical conductivity of the irrigation water (ECw: 0.5, 1.5, 3.0 and 6.0 dS m ). No effects of the factors evaluated on the gas exchange of beetroots were observed. However, the increase of ECw has negative effects on phytomass and growth of this crop, as the application of bio fertilizer favors some soil chemical characteristics.
