“…The weed control through vegetation coverage can occur both through physical effect, preventing the luminous incidence, as through allelopathy effects (Theisen et al, 2000;Favero et al, 2001;Monquero et al, 2009;Favarato et al, 2017).…”

It was evaluated the effects of different types of mulching of soil in the cultivation of crisphead lettuce (Lactuca sativa L.), cultivar “Lucy Brown”, in the spring period, on weed control, soil temperature and productivity. The experiment was arranged in a randomized block design with four treatments and five replications in plots of 14.0m2. The following coverages were studied: Pennisetum glaucum L., Avena strigosa, Brachiaria ruziziensis, plus the control treatment (soil without mulching). The use of mulching of soil, P. glaucum and B. ruziziensis, proved to be a beneficial practice, reducing the soil temperature by up to 5ºC. There was a lower incidence of weeds with the use of the P. glaucum and A. strigosa coverages. The use of mulch did not provide a significant gain in productivity, however, there was a gain regarding the quality of the product, since the coverage with P. glaucum provided an increase in the size of the head (fresh mass of the commercial head).

“…É comum agricultores que adotam a agricultura orgânica manterem policultivos, por potencializar as interações ecológicas benéficas para as plantas cultivadas, incluindo a regulação de populações de insetos danosos aos cultivos (GOMES et al, 2012). Além disso, a manutenção da cobertura morta é uma prática comum na agricultura orgânica quando comparada com a agricultura convencional (FAVARATO et al, 2017). É possível que a maior temperatura do ar ao nível do solo observada nas áreas com cultivo convencional esteja relacionada com a estrutura da vegetação e da cobertura morta, pois um solo menos sombreado e com pouca cobertura morta pode apresentar uma maior temperatura (OLIVEIRA et al, 2005;COELHO et al, 2013).…”

“…Caracterizada pela ausência de organismos geneticamente modificados e a não utilização de agrotóxicos, a agricultura orgânica também não emprega radiações ionizantes e adubos sintéticos que sejam danosos ao meio ambiente e à saúde humana, buscando ainda benefícios sociais e econômicos (SILVA et al, 2010). Além disso, entre as características da agricultura orgânica se destacam os cuidados com o uso do solo, preservando suas características estruturais e mantendo a cobertura morta (FAVARATO et al, 2017). Outro ponto importante é o maior número de plantas cultivadas em relação às áreas de cultivo convencional (KAMIYAMA et al, 2011;SANTOS, 2016).…”

Este trabalho teve como objetivo avaliar a riqueza, a diversidade, a abundância e a composição da fauna de formigas em oito propriedades rurais com cultivo orgânico e oito com cultivo convencional, no município de Paraíba do Sul (RJ). Instalaramse em cada área cultivada 15 armadilhas tipo pitfall para a coleta das formigas. Amostraram-se 48 espécies de formigas no total, pertencentes a sete subfamílias e 23 gêneros. A riqueza nos cultivos convencionais foi de 29, e nos cultivos orgânicos, 38. Os valores médios de riqueza e diversidade de espécies e a abundância média foram maiores nas áreas com cultivo orgânico do que nos cultivos convencionais. O número de espécies cultivadas, a profundidade de cobertura vegetal morta e a temperatura estiveram entre as variáveis que mais afetaram a mirmecofauna. A composição de espécies de formigas variou significativamente entre áreas com cultivo convencional e orgânico (ANOSIM, R = 0,6099, p < 0,01). Os resultados corroboram a realidade de que a prática da agricultura orgânica constitui uma alternativa relevante aos cultivos convencionais, por promover a manutenção da biodiversidade local.

“…Although it is considered a rustic crop, cowpea responds well to improvements in cultivation methods, and for this reason cropping practices designed to raise productivity and promote sustainable development must be tested. Among these technologies, dead soil cover has been used to maintain and/or improve soil fertility, prevent erosion, reduce heat and water loss, and also to suppress weed species (Favarato, de Souza, & Guarçoni, 2017).…”

Dead Cover and Agronomic Characteristics of Cowpea

Dead cover, or mulch, consisting of plant residues, plays an important role for the success of diverse agricultural crops, working as an insulating layer protecting the soil from daytime temperature variations and maintaining the soil moist and rich in organic matter. Cowpea is a source of proteins, carbohydrates, vitamins and minerals. Its importance in the North, Northeast and Midwest regions of the country is associated with economic and social aspects, since it is an important food for low-income populations, supplying their nutritional needs. This study was carried out under greenhouse conditions in Manaus, state of Amazonas, with the purpose of assessing the effect of different dead covers on the agronomic characteristics of cowpea cultivars. It consisted of a completely randomized design in a 4 × 4 factorial arrangement. The treatments comprised four cowpea cultivars (BRS Caldeirão, BRS Tumucumaque, BRS Guariba and BRS Tracuateua) and three species of cover plants (Brachiaria decumbens, Brachiaria ruziziensis and Mucuna pruriens) and one control treatment, without soil cover, in a total of 16 treatments, with four replications and two plants per experimental unit. Analysis of variance was applied to the data, and the means were compared by the Scott-Knott’s test at 5% probability level. The following characteristics were examined: number of pods per plant, pod length, number of seeds per pod, weight of shoot dry matter, and grain yield. Mulching provided better results for all characteristics assessed in the four cultivars when compared to the control. BRS Caldeirão is the recommended cultivar for the state of Amazonas and the other regions with similar edaphoclimatic characteristics (high air temperature, rainfall, air humidity, and low-fertility tropical soils) because it exhibited the greatest number of pods per plant, number of seeds per pod, shoot dry matter, and the highest average grain yield (Freire Filho et al., 2011; Souza et al., 2016).
